KNX 71320 Room Temperature Controller for Fan Coil A C

Specifications

Product Name: KNX eTR 102 FC
Product Type: Room Temperature Controller for Fan Coil A/C
Item Numbers: 71320 (white), 71322 (black)

Description

The KNX eTR 102 FC is a room temperature controller designed for use with fan coil air conditioning systems. It features touch-sensitive buttons for manual adjustment of room climate settings. The controller allows you to set the fan speed (1-3), the desired temperature (using the +/- buttons), and the mode of operation (automatic on/off, air conditioning on/off). The current settings are displayed using LEDs, and you can adjust the= brightness and switch-off behavior of the LEDs as well.
The unit includes a built-in temperature sensor for control purposes. Additionally, it can receive another measured value via the bus and combine it with its own value to obtain an overall temperature.
The automatic room climate control function utilizes a PI controller for both heating and cooling, with options for one- or two-stage systems. The control parameters are specifically tailored for air conditioning systems with fan coils.

Description

The room temperature controller for the KNX building bus system automatically con-trols air conditioning with fan coil units. It has touch-sensitive buttons with which the room climate settings can be manually readjusted. The fan speed (1-3), the setpoint temperature (value, touch buttons +/-) and the mode (automatic on/off, air conditioning on/off) can be set. LEDs show the current settings. The brightness and switch-off be-haviour of the LEDs can be adjusted.
A temperature sensor is integrated in the unit, which can be used for control. To obtain a mixed value, the unit can receive another measured value via the bus and process it with its own value to obtain an overall temperature.
The automatic room climate control includes a PI controller for a heating and a cooling (one- or two-stage). This control contains parameters specifically for air conditioning with fan coil systems (systems with fans).
Room Temperature Controller KNX eTR 102 FC • Version: 06.12.2023 • Technical changes and errors excepted.
The room temperature controller can also be used as an extension unit, i.e. it transmits the manual inputs to another control device in the KNX system, which then takes over the control.
Communication objects can be linked in integrated AND and OR logic gates.

Functions

Operating zone for setting 3 blower levels
Operating zone for temperature control with 2 areas (+ warmer, – cooler)
Operating zone for mode setting with 2 areas (automatic on/off, air-conditioning on/off)
The lighting behaviour of all LEDs is adjustable, so they can be used as ambient lighting, for example, or switched off as long as there is no input
Temperature measurements. Mixed value from own measured value and external values (proportion can be set by percentage), output of minimum and maximum values
PI-controller for heating (one or two-level) and cooling (one or two-level) according to temperature. Regulation according to separate setpoints or basic setpoint temperature. Parameters specifically for fan coil control for fan coil units
2 AND and 2 OR logic gates each with 4 inputs. 8 logic inputs (in the form of communications objects) can be used as inputs for the logic gates. The output from each gate can be configured optionally as 1-bit or 2 x 8-bit

Commissioning

Configuration is made using the KNX software as of ETS 5. The product file can be downloaded from the ETS online catalogue and the Elsner Elektronik website on www.elsner-elektronik.de.
After the bus voltage has been applied, the device will enter an initialisation phase last-ing approx. 5 seconds. During this phase no information can be received or sent via the bus.

Addressing the device

The device is delivered ex works with the bus address 15.15.255. You program a differ-ent address in the ETS by overwriting the address 15.15.255 or teach the device using the programming button.
The programming button is located at the bottom of the device and is recessed. Use a thin object to reach the button, e. g. a 1.5 mm² wire. When the button is pressed, the temperature display on the front flashes.

Display and operation at the device

Adjust room temperature
Depending on the setting of the “Temperature display” parameter in the device application, the Room Temperature Controller KNX eTR 102 FC displays the current room temperature value (or mixed value), the target value or the shift in relation to the basic setpoint. The display can be dimmed and switched off via the bus so that no value is displayed even when touched.

Option A: Display of actual temperature (room temperature)
The current room temperature is displayed. It is not possible to change the room temperature manually using the +/- buttons.

Option B: Display of target temperature or basic setpoint shift
Depending on the setting, the current target value or the shift relative to the base setpoint is displayed. The temperature can be changed by touching the +/- buttons.

Display of the basic setpoint shift (change compared to the basic setpoint of the control):

Tap +:
Increase room temperature (Basic setpoint shift direction PLUS)
Tap -:
Lower room temperature (Basic setpoint shift direction MINUS)

Option C: Display of actual temperature and target temperature/basic setpoint shift
During normal operation, the current room temperature is displayed. By touching the buttons, the display jumps to the target temperature or to the basic setpoint shift, depending on the presetting. Changes with + or – are visible. The display returns to the room temperature if no button is touched for 7 seconds.

Touch the + or – button briefly: The current target temperature (or the basic setpoint shift) is displayed.
Tap +: Increase room temperature (target temperature/basic setpoint shift is increased).
Tap -: Lower room temperature (target temperature/basic setpoint shift is lowered).

General
The step size for the change and the possible setting range are defined in the device application (ETS). There you can also define whether the manually changed values are retained after a mode change (e.g. Eco mode overnight) or reset to the stored values.

Setting the parameters

Behaviour on power failure/ restoration of power

Behaviour following a failure of the bus power supply:
The device sends nothing.
Behaviour on bus restoration of power and following programming or reset: The device sends all outputs according to their send behaviour set in the parameters. Delays established in the “General settings” parameter block are taken into account.

General settings

First set the send delays after reset/bus restoration here.
These delays should be coordinated with the entire KNX-system, i.e. in a KNX system with many participants, care should be taken that the bus is not overloaded after a KNX-bus reset. The messages of the individual participants should be sent offset.

Transmission delay after reset/bus restora- tion	5 s • … • 300 s

The bus load is limited with the aid of the maximum message rate. Many messages per second put a strain on the bus, but ensure faster data transmission.

Maximum message rate|

1 message per second
10 messages per second
50 messages per second

---|---

Temperature measured value

Select, whether a malfunction object is to be sent if the sensor is faulty.

Use malfunction object	No • Yes

When measuring temperature, the self-heating of the device is considered by the electronics. The heating is compensated for by the device.
Use Offsets to adjust the readings to be sent. Permanent measurement variations can be corrected in this way.

Offset in 0.1°C	-50…50; 0

The unit can calculate a mixed value from its own reading and an external value, e.g. in order to determine a room average. Set the mixed value calculation if desired. If an external portion is used, all of the following settings (threshold values, etc.) are related to the overall reading.

Use external measured value	No • Yes

The percentage of the external measured value share of the total value is set here.

Ext. Reading proportion of the total reading	5% • 10% • … • 50% • … • 100%

The internal measured value and the total measured value can be sent to the bus and further processed there by other participants.

The highest (max.) and the lowest (min.) temperature value since programming or a reset can be sent to the bus. The two values can be reset via object no. 27 “Tempera-ture sensor: measured value min./max. reset”.

Use minimum and maximum value	No • Yes

Temperature threshold values

The temperature threshold values are used to carry out certain actions in the KNX sys-tem when a temperature value is exceeded or not reached.

Use threshold value 1 / 2	Yes • No

Temperature threshold value 1 / 2

Threshold value

Decide when threshold values and delay times received are to be kept per object. The parameter is only taken into consideration if the setting by object is activated fur-ther down. Please note that the setting “After power restoration and programming” should not be used for the initial start-up, as the factory settings are always used until the first call (setting via objects is ignored).

Set the threshold values directly in the application program using parameters or define them via the bus using a communication object.

Threshold value setpoint using	Parameter • Communication objects

Threshold value setpoint using parameter
When the threshold value per parameter is specified, then the value is set.

Threshold value in 0.1°C	-300 … 800; 200

Threshold value setpoint using a communication object
During initial commissioning, a threshold value must be defined which will be valid un-til the first call with a new threshold value. For units which have already been taken into service, the last communicated threshold value can be used. Basically, a range is given in which the threshold value can be changed (object value limit).
A set threshold value will be retained until a new value or change is transferred. The current value is saved so that it is retained in the event of a power supply failure and will be available again once the supply voltage is restored.

Enter how the threshold value will be received from the bus beforehand. Basically, a new absolute value can be received, or simply a command to increase or decrease.

Type of threshold value change	Absolute value • Increase/decrease

Choose the step size.

Step size (upon increase/decrease change)| 0.1°C • 0.2°C • 0.3°C • 0.4°C • 0.5°C • 1°C • 2°C • 3°C • 4°C • 5°C
---|---

The switching distance (hysteresis) is important for the output of the value at the switching output.
The switching distance prevents the switching output of the threshold value from changing too often in the event of temperature fluctuations. When the temperature val-ue drops, the switching output does not react until the switching distance falls below the threshold value (options 1 and 2 in the first parameter of switching output). When the temperature value increases, the switching output does not react until the switch-ing distance exceeds the threshold value (options 3 and 4 in the first parameter of switching output).

Setting the switching distance	in % • absolute

Set the value of the switching distance.

Switching distance in 0.1°C	0…1100; 50
Switching distance in % of the threshold value	0 … 50; 20

Switching output
Here it is set which value the output transmits if the threshold value is exceeded or un-dercut.

When the following conditions apply, the|

TV above = 1 | TV – Hyst. below = 0

---|---
output is|

TV above = 0 | TV – Hyst. Below = 1

(TV = Threshold value)|

TV below = 1 | TV + Hyst. above = 0

|

Below TV = 1 | Above TV + Hyst. = 0

Here it is set whether switching delays can be set via objects.

Delays can be set via objects (in seconds)	No • Yes

Switching command delays ignore short-term temperature fluctuations around the threshold value or threshold value and switching distance for the switching output.

Switching delay from 0 to 1	none • 5 s … 2 h
Switching delay from 1 to 0	none • 5 s … 2 h

Here you set the cases in which the switching output is to be sent to the bus.

For an adequate regulation of the ambient temperature, comfort, standby, eco and building protection modes may be used.
Comfort when present, Standby during short absences, Eco as a night-time mode and Frost/heat protection (building protection) e. g. with the window open.
The settings for the temperature control include the setpoint temperatures for the in-dividual modes. Objects are used to determine which mode is to be selected. A change of mode may be triggered manually or automatically (e.g. by a timer, window contact).
The mode may be switched with two 8 bit objects of different priority. The objects are:„… HVAC mode (Prio 2)“ for switching in everyday operation and „. HVAC mode (Prio 1)“ for central switching with higher priority.

The objects are coded as follows

0 = Auto

= Comfort
= Standby
= Eco
= Building Protection

Alternatively, you can use three objects, with one object switching between eco and standby mode and the two others activating comfort mode and frost/heat protection mode respectively. The comfort object blocks the eco/standby object, and the frost/heat protection object has the highest priority.

The objects are

Mode (1: Eco, 0: Standby)“,
comfort activation mode” and
frost/heat protection activation mode”

Switch mode via|

The control can be deactivated and reactivated by an object from the bus. Configure which value of the on/off object should be used to switch the temperature control on or off.

Behaviour of the on/off object with value|

1 = On | 0 = Off
0 = On | 1 = Off

---|---

Set the value of the on/off object after a reset.

The device sends the current control variables of the control system to the bus. Set the cases in which transmission takes place. Periodic sending is safer, in case a mes-sage does not reach a recipient. You may also set up periodical monitoring by the ac-tuator with this setting.

Send control variable|

---|---

When sending on change, the control variables are sent to the bus as soon as they change by the percentage set here.

With sending periodically, the control variables are sent to the bus in a fixed cycle that can be set here.

Cycle

(if sent periodically)

| 5 s • … • 5 min • … • 2 h
---|---

The status of the control variable is defined as 0% = OFF and >0% = ON. This status is sent to the bus and may for example be used for visualisation, or to switch off the heating pump as soon as the heating is switched off.

Then define the type of control. Heating and/or cooling may be controlled in two lev-els.

Type of control|

Single level heating
Dual-level heating

---|---

General setpoint values
Determine if manually or via the bus modified the modified set point values should be kept after a mode change, or if they should reset to the standard specified here.

Keep modified set points after mode change	No • Yes

You may enter separate setpoint values for each mode or use the comfort setpoint as a basic value.
If you are using the control for both heating and cooling, you may also select the set-ting “separately with switching object”. Systems used for cooling in summer and for heating in winter can thus be switched from one to the other.
If no switching object is selected, the actual temperature determines whether heating or cooling takes place. If the actual value is between the heating and cooling setpoint values, the existing operating mode is retained. If heating was
previously used, the system remains in heating mode and continues to aim for this set point value. Only when the cooling setpoint is reached does the operating mode switch to cooling.
If cooling has been used so far, the system remains in cooling mode and continues to aim for this set point value. Only when the heating setpoint is reached does the oper-ating mode switch to heating.
If the actual temperature is above the cooling set point value, cooling takes place; if it is below the heating set point value, heating takes place. The difference between the heating set point value and the cooling set point value or the dead zone should be at least 1 °C. This prevents the control from switching too often between heating and cooling in the event of minor temperature fluctuations.
If you are using the basic value, only the deviation from the comfort setpoint value is listed for the other modes (e.g, 2°C less for standby mode).

| 0 • 1
---|---

If the set point values are set without a switching object, there is a status object. This sends information to the bus as to whether the heating or cooling setpoints are cur-rently being used.
Predefine the increment for the setpoint changes.

Increment for setpoint changes (in 0.1 °C)	1… 50; 10

The control may be reset to comfort mode from eco mode, which is used as night mode, via the comfort extension. This allows the user to maintain the comfort set-point value for a longer time, e.g. when having guests. To do this, place a comfort ex-tension switch on a visualisation or a push-button, for example. The duration of this comfort extension period is set. After the comfort extension period expires, the system returns to eco mode.
Whether the change only remains active temporarily (do not save) or remains saved after voltage recovery (and programming) has already been defined in the first section of “General control”.

Comfort Setpoint
Comfort mode is usually used for daytime mode when people are present. A starting value is defined for the comfort setpoint as well as subsequently a temperature range in which the setpoint value may be modified.

Setpoint values for frost/heat protection (building protection)

The building protection mode is for example used as long as windows are opened for ventilation or during longer absences (e.g. school buildings during holidays). Set-points for frost protection (heating) and heat protection (cooling) are determined which may not be modified from outside (no access via operating devices etc.). The building protection mode may be activated with delay, which allows you to leave the building before the controls switch to frost/heat protection mode.
Predefine the setpoint for frost protection (heating).

Heating control level 1/2

If a heating control mode is configured, one or two setting sections for the heating lev-els are displayed.
In the 1st level, heating is controlled by a PI control, which allows to either enter control parameters or select predetermined applications.
In the 2nd level (therefore only in case of 2-level heating), heating is controlled via a PI or a 2-point-control.
In level 2, the setpoint difference between the two levels must also be specified, i.e. be-low which setpoint deviation the second level is added.

---|---

The settings for the ‘controller extension’ option are described below. For configura-tion as a stand-alone controller, please see Chapter Temperature PI control – Inde-pendent controller, page16.
The mode may be switched with two 8 bit objects of different priority. The objects are:„… HVAC mode (Prio 2)“ for switching in everyday operation and
HVAC mode (Prio 1)“ for central switching with higher priority.

The objects are coded as follows

0 = Auto

= Comfort
= Standby
= Eco
= Building Protection

Altern

atively, you can use three objects, with one object switching between eco and standby mode and the two others activating comfort mode and frost/heat protection mode respectively. The comfort object blocks the eco/standby object, and the frost/heat protection object has the highest priority. The objects are:
Mode (1: Eco, 0: Standby)“, „. comfort activation mode” and frost/heat protection activation mode”
