OVERVIEW

The Hevac ENDEAVOUR is a fully programmable microprocessor based Universal controller with 5 analogue & 4 digital inputs + 5 relay & 2 analogue (0-10vDC) outputs.

Run (start) operation can be triggered via an internal 365 day Time Switch, Run Timer & or external Auto/Off/Manual connected switches. Modbus capability also allows the controller (or controllers) to be connected to a local HMI color touch screen or (coming soon) to the Internet via a gateway module for remote monitoring & override. A 2nd independent time switch is also included for auxiliary independent time switch requirements.

This latest software update also features an additional independent 2nd I/O control loop capability, the expanded power of input X4 allows the Endeavour to now be used as a general purpose Universal Controller measuring & controlling some medium other & or temperature, making this version extremely powerful & flexible.

The controllers I/O are displayed via a scrolling backlit LCD screen giving plain English status together with 5 dedicated LED’s showing the relays on/off state (which can be labeled on the face plate with a marker). Typically used for Air Conditioning control applications where On/Off control of Heating & Cooling stages and /or modulating control of actuators / devices requiring a variable 0-10vdc control signal is required.

The Endeavour can also be set to “Time Switch only” mode with all other non timer capabilities disabled allowing this controller to be used as a 2 channel 365 day Time Switch only. The 4 programmable relays & the 2 analogue output “use” (modes) can be set as : Heat, Cool or Both (both means the output operates as both a heating and a cooling output) or can now alternatively be set to respond to an external rising or falling scalable universal input signal (0-10v or 4- 20mA) on terminal X4. The relays can also be tied to respond to either analogue output. The 5th relay is dedicated as a System

Run (Fan / Main Time Switch) relay which can be set to operate continuously whilst the controller is enabled or to cycle on & off with a heat or cool run call (typical for domestic A/C systems).

The 2 analogue outputs can be set to P or P+I mode (proportional+ integral action) and the minimum & maximum signal levels can be range limited, any minimum value setting is automatically overridden to zero when the system is off which is perfect for EC fan time switch control when a minimum speed requirement is needed when triggered to start.

Also new to this latest update, the main temperature setpoint can be shifted (reset) due to outside temperature & room humidity levels. O/A temperature particularly influences how we dress & together with room humidity affects our perception of environmental comfort, shifting the operating setpoint (following outside air temperature) also substantially saves energy operating costs.

OPTIONAL REMOTE INTERLOCKS & OVERRIDES

• Remote System AUTO / OFF & AHR operation can be easily added by simply connecting a normally open (N/O) switch anywhere convenient in parallel with the main (passive) thermistor temperature sensor wires X1 & M. Momentarily shorting X1 & M results in triggering a run timer function (typically as an after hours timer function) or / & constant shorting of X1 & M for more then 2 seconds results in a system OFF function. Manual override functions are also available at the controller terminals “D1,D2 & M” for Auto/Off/On & AHR operation. From version v2.26+ input D2 can be connected to a movement sensor to trigger the Endeavors adjustable run timer.

• For auxiliary control interlocks spare relays or analogue outputs can be controlled by an independent passive Hevac temperature sensor (-D type) or by any type of 0-10vDC or 4-20mA input (scalable) on terminal X4 with a programmable appropriate designator ie C, %, pa, ppm, CO2, Volt. Using both inputs X1 & X4 the Endeavour is now affectively 2 independent controllers in one, making the Endeavour a powerful dual loop Universal controller.

• The controller has Modbus communications capability for connection of up to 32 controllers to our color HMI wall (or switchboard door) display panel for zone status, individual setpoint adjustment & system Auto/Off/On override. Alternatively upto 247 controllers can be connected to a 3rd party BMS system for remote control & monitoring.
  A BMS can also monitor 2 dedicated digital inputs, “D3” is a A/C fault input & “D4” is a general purpose on/off status input that could be used for example to monitor & prove supply air fan running operation via a mechanical pressure switch. In the near future this controller can be monitored / overridden via a gateway module connected to the Internet.

• With an optional O/A sensor connected, the Economy cycle damper operation (Y1 output) for temperature control can be interlocked for free heating, cooling or both when the outside air temperature conditions are favorable. The use of outside air for temperature control can also be inhibited if the outside air temperature falls below an adjustable minimum O/A temperature (factory set at 12c for DX or FCU coil protection .This O/A temperature input can now also be used to automatically reset the controllers operating setpoint in relation to the outdoor temperature for energy saving & greater comfort control. Input X4 can also reset the controllers setpoint due to measured room or O/A humidity.

• With an optional CO2 sensor connected, economy cycle dampers can also be overriden & proportionally driven to the fresh air mode to reduce high CO2 levels. The maximum damper output signal for CO2 control can be restricted in extreme O/A temperatures so as not to lose temperature control, all settings are user adjustable. The CO2 input can now also control spare relays for on/off CO2 control.

• Remote Set Point devices (either passive or active) can be connected to the controller. If a passive adjuster is connected (default setting), the controller will automatically detect and hand over set point adjustment authority to the remote device (then ignoring the controllers UP & DOWN buttons). The remote set point adjustment can be built into a room temperature sensor (SRT-DSP or HSMO-DAT) or as a separate stand alone device giving remote setpoint control only (SPA-D). The range of the passive remote setpoint (0-10k) is fixed at 18 to 25 degrees or if an active remote setpoint is used (0 to 10v) the 0-10vDC is adjustable for a range of 0-100c.

As a service aid any remote setpoint device can be temporarily virtually disconnected by holding the UP & DOWN buttons together for 5 seconds which hands conventional setpoint control back to the controller to aid in commissioning & testing & will automatically return to remote control after 10 minutes or can be cancelled anytime by again pushing the UP & DOWN buttons together.

VIEW EVENT HISTORY (DATA LOGGER)

The ENDEAVOUR incorporates a basic event data logger that records the last 250 “ON” switching events.

example

1. RELAY 3 ON 15/10/2019 16:30
2. RELAY 2 ON 15/10/2019 16:50
3. NIGHT PURGE ON 16/10/2019 04:35

The history can be reset & cleared by pressing the UP button from the 1st event which prompts an “erase history message” question ..pressing ENTER clears the history.

SET START BY METHOD ( A/C STOP / START OPERATION )

To set the A/C system “START BY” method, press the fascia button labeled “ENTER” then press the DOWN arrow button until the LCD display displays

“ SET START BY METHOD ”
Press the ENTER button to open this menu & see the existing setting, use the UP & DOWN buttons to cycle through the 3 choices :

“TIME SWITCH”, “RUN TIMER” or “MANUAL”.
Select your choice by pressing the “ENTER” button.
The display will then return to this parent menu.
Exit to the normal running screens by pressing the “ESC” button or scroll to another main menu item to edit or check using the “UP” or “DOWN” arrow buttons.

1. TIME SWITCH (1) System enabled by the controllers internal main 7 day Time Switch, which can be programmed for a total of 18 possible switching events for individual or groups of days (allowing multiple on/off times per day).
2. RUN (for) TIMER System operation triggered by a momentary on/off pulse from a switch wired in parallel with the 2 (passive) sensor wires or across the controllers D2 & M terminals. Adjust the timer for the required time i.e. 8 hours. This feature can also be triggered from a movement sensor (turn toggle off setting to NO.)
3. MANUAL – System 24/7 ON or ON/OFF state set only by an external “System Switch” or external interlock wired in parallel with the 2 sensor wires connected to our passive temperature sensor or alternatively shorting the controllers D1 & M terminals which has the same affect resulting in a “System Off” mode with all relays and analogue outputs de-energized,

SET CLOCK (TIME & DATE SETTINGS)
To edit the controllers time and date settings, press the fascia button labeled “ENTER” and using the DOWN button scroll down the menu until.. “SET CLOCK” is displayed. Press the ENTER button to check and edit the controllers time, date and day light saving enable (or disable) settings. Daylight saving, if enabled, starts on the 1st Sunday in October (at 2am) and finishes on the 1st Sunday in April (3am)

SET MAIN TIME SWITCH (1)

The controller’s internal main time switch (1) (if enabled for use) can be easily programmed for any combination of ON/OFF switching times for any day of the week. The controller comes preset with factory default settings for operating the system: Monday to Friday from 08:00 (event 01) until 17:30 (event 02). To edit settings, press the fascia button labeled “ENTER” and scroll down through the menu tree until “SET MAIN TIME SWITCH (1) ” is displayed. Press the “ENTER” button to open this menu. The existing detail for switching event 01 is displayed. Unlike other time switches, this controller has very flexible unassigned switching events (instead of fixed sequential ON then OFF routines). Time switching events can be set to switch (change state) at any time & day/s, and set as a switching ON event or OFF event. Typically the switching events would be programmed in the order of ON events (with common days & time) followed by an OFF event with matching days and common OFF time, but any variation is easily programmed. As an example: switching events could be programmed such that switching event 1 (01) turns the system ON for Monday to Friday at 08:30, followed by event 2 (02) turning the system ON Saturday & Sunday at 09:00, then event 3 turning the system OFF Monday to Sunday at 17:30. With this programming approach, multiple & varied ON / OFF events can be set on individual or groups of days, plus there is no issue switching past midnight which most other time switches cant achieve. 18 switching events are available.

SET AUXiliary TIME SWITCH (2)

The controller’s independent Auxiliary Time Switch (2), if enabled for use, can be assigned to any spare relay not already used, and is assigned to a spare relay in the Relay Programming Menu. The Auxiliary Time Switch is basically intended as a simple auxiliary time switch for controlling other equipment not directly associated with temperature control ie : toilet exhaust fans etc, and is programmed using a more conventional time switch technique with programmable “ON” time events followed by “OFF” time events for the relevant days of the week. Note : This Auxiliary time switch has only two sets of ON & OFF settings (paired events) which would typically cover the separate on & off times for week days and weekends. To edit settings, press the fascia button labeled “ENTER” and scroll down through the menu tree until “SET AUX TIME SWITCH (2) “is displayed. Press the “ENTER” button to open this menu. If previously unused the 1st event (01) will display “UNUSED”. Press the ENTER button to start editing. Press the UP button to change this event to “ENABLED” which is the 1st fixed “ON” event. Press ENTER which will then display an LCD screen to ‘enable’ the required days , use the UP / DOWN & ENTER buttons to sequentially set “Y” to all days that are to be enabled for this 1st (same) “ON” time ( leave as “–” for disabled days) .After Sunday is entered the display will jump to the “ON” time setting screen – use the UP / DOWN buttons to set the “ON” time, then press ENTER. The controller will then ask should this Auxiliary Time Switch be overridden (to OFF) by the programmed holidays ? (as set in the controllers “HOLIDAY” assignment menu), set “YES” or “NO” using the controller’s UP / DOWN buttons and press ENTER. The display returns to this event screen (01). Press the DOWN arrow button to move to the next event screen (02) which is the 1st fixed “OFF” event setting screen, which is in respect to the previous “ON” setting -press ENTER. IF not already “ENABLED” press the DOWN arrow button to ENABLE this event, Press ENTER. Repeat the Y / — setting for each day of the week which should be set to match the previous “ON” settings, then set the common “OFF” time for these days, press ENTER. Press the ESC button to exit Time Switch 2 programming if only one common on/off times for the week is required or press the DOWN arrow button until event (03) is displayed which is a 2nd (fixed as) ‘ON’ setting ~ Repeat the procedure per events (01) & (02) to set the ON (03) & OFF (04) times & days for these events. The Auxiliary Time Switch is now programmed , press “ESC” a few times to exit out to the main running screen.

RUN / AHR TIMER

Whether the Run Timer is used as a short duration type “After Hours”(AHR) Run timer (if the system normally operates by the controllers internal time switch), or set for a longer period, typically as a “Run (For) Timer”, the procedure to set up the timer is the same. The timer trigger inputs “D2” or “X1” can be set such that new input pulses causes a toggle on/off or to restart the timer (which suits the use of movement sensors to trigger timer function).

LOAD HOLIDAYS (OFF OVERRIDE) SETUP

Individual or group of dates can be programmed as holiday time switch “OFF” overrides. To edit or set Holiday dates, Press the fascia button labeled “ENTER” to have the LCD display jump to the 1st menu item in the menu tree – “SET CLOCK” scroll down through the menu tree with the “DOWN” arrow button until “LOAD HOLIDAYS” is displayed. Pressing the “ENTER” button will then display either the 1st existing Holiday date or HOLIDAY DISABLED. If disabled, press the “DOWN” button to change to ENABLED. Once enabled, the 1st holiday default start date of 1st JAN (01) will be displayed, (01) means the 1st holiday. Using the “UP or DOWN” buttons scroll through calendar dates until the required 1st HOLIDAY START date is displayed, press “ENTER” to then also program the 1st HOLIDAY END date which can either be the same as the start date (if a single day holiday) or a future inclusive date for a group of days (i.e.: Easter or a school holiday term break). The controller asks after each holiday is set whether this holiday OFF override event should only execute once or repeat each year on the same date(/s), set as either ONCE or REPEAT using the “UP” or “DOWN” buttons, press “ENTER” to accept settings then the “DOWN” button to jump to the next holiday start date to program. Repeat this procedure until all holiday dates are set.

NIGHT PURGE SETUP

With this feature enabled it is possible to setup a low running cost building night time ventilation purge cycle, to vent built up heat from within the building with cooler outside air in order to reduce the cost of mechanical cooling during occupancy hours at startup. During the user programmable enable times, if the room temperature is above the main set point and the measured outdoor temperature is cooler by an adjustable amount to the room temperature, this software will cause the supply fan (connected to relay 5) to energies & the modulating motorized economy cycle dampers (connected to analog output Y1) to reposition to the full fresh air mode. These output states are maintained until the room temperature drops to a settable temperature difference in relation to the outside air temperature or / & the O/A temperature rises above the room temperature setpoint, or the enable time ends.

“On Temp Diff ” is the amount of temperature that the outside air has to be cooler then the room temperature before purge mode is allowed to trigger night time purge ventilation mode.
“Off Temp Diff ” is the temperature difference to the room temperature for purge cycle to turn off. This cycle can repeat during the programmed night purge period, But always subject to the room temperature being above the normal operating control setpoint.
The purge cycle ends regardless at the programmed end operating time.

SCREEN DISPLAY

The Endeavors information LCD screens will by default Auto Scroll displaying one information screen (page) after another relative to the I/O that has been programmed. Alternatively if auto scroll is not preferred the screen can be set to remain on any page and other screens than displayed by pressing the “ESC” button.
To change the default auto scroll setting , press the “ENTER” button and scroll down the menu until “SCREEN DISPLAY” is shown, press “ENTER” and toggle the choice
“[Y]” (YES) or “[N]” (NO) using the UP or down buttons.

CONTROLLER FUNCTION MAIN USE OF CONTROLLER

The Endeavour controller can be set to operate as a standard temperature controller for control of A/C & Fan Coil Units etc (default use) or set in a reduced control mode as Time Switch or X4 I/O only mode which if selected inhibits most other functions not relative to the reduced mode.
In Time Switch only mode functions enabled are Time Switch 1, Time Switch 2 , Run Timer & AUTO /OFF / ON system overrides modes, this mode responds to time settings under
“Time Switch 1” & outputs on relay 5 ( terminals 5 & 8 ).
NOTE : Y1 & Y2 can also be used in this mode & set to a minimum value to use as a time switch controlled fixed analogue output control ..ie to time switch control an EC fan but at a fixed speed.
In X4 only mode, only the secondary control loop using X4 as the sensor input is used driving programmed relays or analogue outputs as required as for example to control a modulating pressure controlled bypass valve using a differential pressure sensor connected to the X4 input.

PLEASE CYCLE THE POWER OFF & ON AFTER CHANGING TO THIS APPLICATION TO LOAD PROGRAM INTO MEMORY

PRE-SET PROGRAMS (USER SELECTABLE TO SUIT SITE A/C CONTROL REQUIREMENTS)

The Endeavour is pre-loaded with eleven preset programs to suit most typical control interlock requirements for reverse cycle air conditioners, fan coil units & AHU’s.
To select a preset program press the “ENTER” button to enter the menu system and scroll down the list until “PRESET PROGRAMS” is displayed, press ENTER to see the current selected program , using the UP or DOWN buttons scroll to the desired suitable program and press ENTER to load this new preset into the controllers memory, its a good idea after this action to cycle the controllers power to ensure the new program is loaded into the microprocessors operating system. The controller will also load these nominal defaults :

X1,2,3 & 4 SET TO PASSIVE IN SOFTWARE (ALSO SET TO PASSIVE BY DEFAULT IN HARDWARE BY JUMPERS ON BOTTOM PCB – see page 23)

R5 FAN CONTROL METHOD

The ENDEAVOUR has the ability to cycle the fan relay (R5) with heat / cool demand whilst the air conditioning system is enabled to run (whether that be “ON BY” : Time Switch, Run Timer or set to operate by Manual on/off switch) . R5 can be set to remain ON continuously (default) during the ON running period of the system or be set to cycle on & off when a relay programmed as a heating or cooling temperature control stage starts & stops. To set the fan control method of R5, press the fascia button labeled “ENTER” and scroll down through the menu tree until “ R5 FAN CONTROL METHOD ” is displayed. Press the “ENTER” button to open this menu. The existing method is displayed. The fan cycle method is a typical mode of fan operation in a domestic installation to save on power & noise but in commercial buildings typically regulations call for the fan to remain on continuously whilst the building is occupied to meet minimum building ventilation requirements, if however minimum ventilation is achieved by some other means, it may be preferable to have the fan cycle with the heating or cooling as required to reduce drafts & noise when the temperature is comfortable.

Y1 & Y2 ANALOGUE (OUTPUTS) EDITING

To set or edit the two analogue outputs (Y1 & Y2) for mode of operation and output characteristics, Press the fascia button labeled “ENTER” to have the LCD display jump to the 1st menu item in the menu tree – “SET CLOCK”. Scroll down through the menu tree with the “DOWN” button until “Y1 & Y2 ANALOGUE PROGRAMMING” is displayed. Press the “ENTER” button to open this menu. A summary screen is then displayed for Analogue output Y1, The other analogue output Y2 summary screen can be seen by simply scrolling down this sub menu using the “DOWN” arrow button. To edit the parameters for a particular analogue output, whilst at its summary screen press the “ENTER” button to display its 1st item to edit which is “MODE” of operation -: the analogue outputs can be set as a DISABLED, COOL ONLY, HEAT ONLY, “HEAT & COOL” , X4 RISING, X4 FALLING. “HEAT & COOL” (BOTH) means the analogue output will function as both a heating and a cooling output with its parameters mirrored to operate on either side of the controller’s setpoint: if for example the dead band is set to 1 degree, then the analogue output will start to produce a DC output voltage from 1 degree above and 1 degree below setpoint. If an analogue output is not needed it can be set to “DISABLED”. If both Y1 & Y2 are both disabled they will not appear in the scrolling running display screens. It is also possible to set each Y outputs min & max O/P values, but note the minimum value is overridden and set to 0v when the controller is in the OFF mode. The two Y analogue outputs can be interlocked to control a spare internal relay on either a rising or falling signal typically used to interlock a relay function with the modulating travel of an actuator to act as an axillary switch.
Y1 & Y2 can now also be directly controlled from X4 to function as an independent analogue control loop.

EXAMPLE OF ANALOGUE SUMMARY SCREEN

• Y = ANALOGUE O/P # (Y1 or Y2)
• M = MODE OF OPERATION (H,C or B)
• D_B = DEADBAND (0-25c)
• P_B = PROPOTIONAL BAND (1-25c)
• P+I = INTEGRAL TIME (1-60min or -P- only)

• MODE : Y output used as a Heating O/P, Cooling O/P or set to act as BOTH (mirrored Heating & Cooling O/P), or to directly respond to the X4 analogue input.
• DEADBAND : The temperature gap from the controller’s setpoint till the Y produces an O/P
• PROB(portional) BAND : The change of temperature over which the Y O/P would increase to 10volts
• INT(egral) TIME : Time in minutes that the integral action adds the P only output to itself over the integral time setting. Note P+I action starts as the output produced by proportional only O/P exceeds 10%.

Another possible alternative use for the Y1 & Y2 analogue outputs could be for use as an EC FAN time switch controlled run & speed setting module, the controller could be set to time switch only mode but with Y1 (as an example) set to a minimum output of 50% (which is still accessible even in time switch only mode). When the time switch 1 is ON, Y1 would produce 5v (EC fan ~ 50%) and when the time switch turns off the Y1 output would return to 0v output.

• CN1-2 :X2 REMOTE SETPOINT
• CN2-1 : X3 O/A SENSOR
• CN2-2 : X4 AUX. ANALOG INPUT
• CN3-1 : X5 MODBUS A
• CN3-2 : X6 MODBUS B
• CN3-3 : X7 CO2 SENSOR OR MODBUS SHIELD

TO USE ACTIVE SENSORS INSTEAD OF PASSIVE , MOVE JUMPERS AS INDICATED.
MODBUS ( TERMINALS X5 & X6) ARE FACTORY SET TO COMMS MODE “C” USING THE CN3-1 & 2 JUMPERS. ALSO
IF X7 ISNT BEING USED AS A CO2 SENSOR INPUT, MOVE CN3-3 TO THE C POSITION & USE X7 FOR CABLE SHIELD CONNECTION.
X1-X4 can now also be set to 4-20mA current inputs (CN mid 2 pins) as an alternative active input instead of 0-10vdc.

X1 TEMP. SENSOR CONFIGURATION (sensor type & span settings)
X1 is the main temperature sensor input that the operating setpoint relates to. The input can be set either as a Passive (Hevac type -D sensors) (default) or as an Active type (0-10vdc) in software but must also be selected as a passive or active type in hardware with a small jumper (CN1) on the bottom circuit board to match the software setting. Offset (cal) adjustment is settable for both passive & active types & for active sensors the maximum range is also adjustable ie: 10v = 20 ~ 100c

LAST STATE DISPLAYED

Note if active sensor type is selected, it is also necessary to reposition a physical input select jumper on the controller’s bottom pcb. Remove screws holding the lid to base and hinge lid to the right, locate the row of red jumpers located under the X1-X7 terminal strip. Reposition the very left jumper to short the top two pins (V position) for active sensor selection. The bottom two pins (T position) are used for passive resistance type sensors selection (factory default)…SEE PAGE 19. For active sensors also note 0v equates to 0c unless offset by the offset setting.

X2 REMOTE SET POINT CONFIGURATION

A Remote Set Point device (either passive or active) can be connected to the controller. If a passive adjuster is connected (default setting), the controller will automatically detect and hand over set point adjustment authority to the remote device (then ignoring the controllers UP & DOWN buttons for set point adjustment). A (passive) remote set point potentiometer can be built into a room temperature sensor – Hevac room sensor model SRT-DSP or supplied as a separate stand alone device model SPA-D. The range of the passive remote set point is fixed at 18 to 25 degrees over 0 to 10K. If an active remote set point is used the 0-10vDC signal is configurable from -5 to +5c for 0v & adjustable upto 100c for 10v.
Note when in active mode, input voltages below 0.5 disable remote setpoint.

Note if an active 0-10vdc remote setpoint input is selected, it is also necessary to reposition a physical input select jumper on the controller’s bottom pcb. Remove screws holding the lid to base and hinge lid to the right, locate the row of red jumpers located under the X1-X7 terminal strip. Reposition the 2nd jumper from the left to short the top two pins (V position) for active S/P selection. The bottom two pins (T position) are used for passive resistance 0-10K potentiometric type selection (factory default)…SEE PAGE 19.
For active remote setpoints also note 0v equates to 0c unless offset by the offset setting (+/- 5c), wheras 0 k ohm = 18c (which can also be offset by +/- 5c)

Note : as a service aid, any remote setpoint can be virtually temporarily disconnected and return setpoint control back to the Endeavour UP & DOWN buttons. Press & hold the UP & DOWN buttons for 5 seconds to trigger this mode. Setpoint control will automatically return to remote control after 10 minutes or can be reset by again pressing & holding the UP & DOWN buttons.

X3 O/AIR TEMPerature SENSOR CONFIG. (+ O/A INDUCED S/P SHIFT)

Economy cycle operation using analogue output Y1 can be interlocked with an outside air temperature sensor (either passive or active) connected to terminal X3, such that the use of a modulating motorised economy cycle damper set is inhibited for temperature control unless the outside air temperature is more favorable for temperature control then using recycled air from the controlled space. A low limit outside air temperature can also be set to inhibit Y1 economy cycle output if the O/A temperature is below an adjustable setting.

X3 Can now also be used for outdoor compensation (reset) of the controllers temperature setpoint so as to match temperature comfort perceptions relative to the outdoor temperature. Winter & summer start, range & authority settings are all adjustable in the menu.

To enable the outside air temperature input, Press the fascia button labeled “ENTER” to have the LCD display jump to the 1st item in the menu tree “SET CLOCK”, then scroll down the menu tree list with the “DOWN” arrow button until “X3 O/AIR TEMP.CONFIGURATION” is displayed. Press the “ENTER” button to open this menu and the existing status is displayed. If “DISABLED” is displayed press the “DOWN” arrow button to change the setting to ‘ENABLED” then press “ENTER”.
Use the screen legend on page 19 to enter & edit settings.

WHY USE OUTSIDE AIR TEMPERATURE & ROOM HUMIDITY TO RESET OPERATING SETPOINT
In summer & winter we typically dress & acclimatize to higher & lower temperatures which lends itself to increasing the controllers operating setpoint in summer and decreasing it in winter to track peoples temperature feeling of comfort. Humidity also plays a part in the perception of comfort ..on humid days even at 23, it can feel much warmer due to the bodies reduced ability to sweat, so dropping the setpoint aids in the feeling of comfort, and raising the setpoint on very dry days can also increase the perception of comfort due to very dry air evaporating the bodies sweat more quickly causing a body cooling affect. If these reset features are enabled, the controller will load pre-set appropriate settings that offer both energy savings and increased perception of comfort control, but all settings for the temperature & humidity reset effects on the controllers setpoint are adjustable.

X4 AUXILIARY INPUT CONFIG. (+ HUMIDITY INDUCED S/P SHIFT)

X4 is a universal auxiliary analogue monitoring & control input & can be used simply to measure & display another resistance (passive) temperature sensor (ie supply air temp.) or any active 0-10vdc input. The input can be used to control spare internal controller relays or “Y” analogue outputs for auxiliary control requirements, ie a relay output in response to a 0-10vDC output from humidity sensor connected to X4. This input value is available in the modbus output for zone display information to the Hevac HMI panel or to a 3rd party BMS system. If the input is 0-10v type it must be set both in software & hardware by a small jumper (CN2-2) on the bottom circuit board to match the software setting. Offset (or cal) adjustment is settable for both passive & active types, for active sensors the maximum range is also adjustable ie: max input of 10v = 500c, 100%, 200pa, 2000ppm or 10 volts. X4 can now also be used as a humidity input to reset (shift) the controllers operating setpoint for greater comfort control due to extreme humidity values. To set the input to active mode remove screws holding the lid to base and hinge lid to the right, locate the row of jumpers located under the X1-X7 terminal strip. Reposition the CN2-2 jumper (4th of 7 jumpers from left) to short the top two pins (V position) for active voltage sensor selection or mid “i” pins for current type. The bottom two pins (T position) are used for passive resistance type sensors selection (factory default). For X4 operating a “Y” output , the output can be set to P only or P+ I, .

X7 CO2 ECONOMY CYCLE OVERRIDE SETTINGS

Enable this Input if a CO2 sensor is connected to the controller for air quantity control to reduce CO2 build up, by either overriding the economy cycle damper operation connected to analogue output terminal Y1 (to increase fresh air intake) or / & to control an internal relay set for on/off CO2 control. Typical settings (factory default if enabled ) are to proportionally modulate open the economy cycle damper set to the fresh air mode as CO2 levels exceeds 700 ppm and cause full fresh air mode if levels reach 1000 ppm, or with this latest update can now alternatively just operate a relay for on/off CO2 control ..ie for energizing a fresh air fan.

To edit settings, press the fascia button labeled “ENTER” to have the LCD display jump to the 1st menu item in the menu tree “SET CLOCK”, using the DOWN arrow button scroll down the menu until “X7 CO2 SENSOR CONFIGURATION” is displayed. To then enable this feature, Press the “ENTER” button followed by the “DOWN” arrow button to change the “DISABLED” setting to ‘ENABLED”. Either except the default settings of (Y1 damper output) start at 700 and range over 300 ppm or edit the values with the “UP” or “DOWN” buttons, press “ENTER” to confirm settings. Note so as not to lose temperature control in extreme outside air temperatures, O/A temperature limits can be set to inhibit full fresh mode due to high CO2 levels when the outside air temperature is either to hot or too cold (adjustable). In this menu set the high and low outside air temperatures where fresh air mode output signal (due to CO2 control) should be restricted (factory settings are: below 10c and above 35c), the now restricted CO2 generated Y1 output signal is adjustable from 0 to 100% (factory setting is 50%). This CO2 input can also control spare internal relay/s for on/off CO2 interlocks (ie Hi/Low fan speed)..see relay programming.

MODBUS SETUP

Modbus connections X5 (A) & X6 (B) are factory hardware enabled by default using the bottom circuit board input pins CN3-1&2. Note If X7 isn’t used for CO2 measurement, X7 can be set as ground source as a modbus shield connection by setting input pin CN4 to the “C” position, otherwise the shield wire needs to be connected to a good earth. Ex factory software modbus settings are disabled , once enabled default address = 1 & Baud rate set to 38400. Address range is Selectable from 1 to 247 & Baud rate selectable as 2400, 9600, 19200, 38400, 57600 & 115200.

TIPS & TRICKS

1. Sometimes its desirable to have an electrically independent system RUNNING output same as the endeavors relay 5 (time switch /fan output) to drive a System Run Lamp or energize some auxiliary device when the A/C system is on (ie fan coil unit run interlock to open/close fresh air damper ). A trick to achieve this is to program relay 1 for “BOTH” (heat & cool mode), set the deadband setting to zero, the switching differential to 5.0 & the time delay to zero. This will have the affect of overloading the temperature On logic for this relay > locking this relay on when the system is in running operation (ie time switch on). Use relay 1’s terminals 1,2 & 3 as required for this electrically independent output.
2. A dedicated AHR (only) ON Lamp output (after hours or run timer on) can be achieved by also using the 2nd independent time switch. Set relay 1 as Auxiliary Time Switch 2 mode and set its on /off times to the opposite of the main time switch on/off time settings. Then connecting relays 1 & 5 as a series circuit (active in on 5, than 8 looped to 1, output to lamp from 3). The AHR lamp will illuminate only when the run timer is triggered as affectively both time switch circuits (wired in series) are now on.
3. A fixed DC output voltage as an on/off output can be set using a spare Y output (as an example a fixed speed setting to an EC fan). In programming set both the Y’s output min & max settings to the desired fixed value to produce a fixed output however this output will still drop to zero when the system is off. This Y output can also be interlocked with a spare relay reacting to an analogue inputs X1 or X4 as an on/off fixed dc output due to the analogue input valve.
4. For applications requiring two different setpoints a remote switch or using the controllers 2nd time switch could be used to switch in a fixed dc voltage from a spare Y output into terminal X2. When the feed into X2 is disconnected the controller will use its setpoint as set using the controllers up/down buttons, when the feed to X2 is made the controller will use this input as the setpoint value i.e 0-10v = 0-50c.
5. Virtual Actuator Auxiliary switch relative to one of the controllers Y outputs can be set using a spare relay
   (typically R1) that can be set to react to the output voltage of a Y output or alternatively for motors with a feedback output this output could be connected to X4 to control a spare relay ie to switch a fan on when a damper is 90% open.
