PRODUCT DESCRIPTION
The JADETM Economizer System is an expandable economizer control system, which
includes a W7220 Economizer Module (controller) with an LCD and keypad. The
W7220 can be configured with optional sensors.
The W7220 Economizer Module can be used as a standalone economizer module
wired directly to a commercial set back space thermostat and sensors to
provide Outdoor Air dry-bulb economizer control.
The W7220 Economizer Module can be connected to optional Sylk Bus sensors for
single or differential enthalpy control. The W7220 Economizer Module provides
power and communications on the Sylk Bus for the Sylk Bus sensors.
The W7220 Economizer Module automatically detects sensors by polling to
determine which sensors are present. If a sensor loses communications after it
has been detected, the W7220 Economizer indicates a device fail error on its
LCD.
System Components
The JADETM Economizer System includes an Economizer Module, 20k mixed air
sensor, damper actuator, an optional CO2 sensor, and either a 20k outdoor air
temperature sensor or Sylk Bus sensors for measuring Outdoor Air and return
air enthalpy, temperature, and humidity.
Economizer Module
This is the core of the JADETM Economizer System and includes the user
interface for the system. The W7220 Economizer Module provides the basic
inputs and outputs to provide simple economizer control. When used with the
optional Sylk Bus sensors, the Economizer Module provides more advanced
economizer functionality.
Sylk Bus Sensors (optional)
The Sylk Bus Sensor is a combination temperature and humidity sensor which is
powered by and communicates on the Sylk Bus. Up to three sensors may be
configured with the JADETM Economizer Module. See page 2 for details.
CO2 Sensor (optional)
A CO2 sensor can be added for Demand Control Ventilation (DCV). Either an
analog (2-10 Vdc) or a wallmount Sylk bus TR40 CO2 sensor can be used with the
Jade economizer.

JADETM ECONOMIZER MODULE
sensor is required for all applications and is mounted in the mixed air
section of a rooftop unit either directly to the sheet metal using self
tapping sheet metal screws or in the air stream using the duct mounting kit.
Duct mount kit is part number 50053060-001.
Optional OA, RAa and DAb Sylkbus sensors communicate with the W7220 on the
two-wire communication bus and can either be wired using a two pin header or
using a side connector. Each Sylkbus sensor includes a two pin side connector
with the packaging. The SKU number of the Sylkbus sensor is C7400S. All OA, RA
and DA sensors are the same SKU number. The sensor is set for the appropriate
type of sensing using the three position DIP switch located on the sensor. OA
position is OFF, OFF, OFF; RA is ON, OFF, OFF and DA is OFF, ON, OFF. During
installation the sensors are set for the usage desired. See “Sylk Bus Sensor
Wiring” on page 7 for DIP switch details.
NOTE:
The protective film on the dip switch is only necessary during the factory assembly process. Simply push through the film to set the dip switches; this will not harm the device.
Once installed, a sensor can be changed to a different application by simply changing the DIP switch setting.
Sensor Mounting
The sensors can be mounted directly on to the sheet metal of unit or can be
mounted in the air stream using the duct mounting kit (order separately).
The kit contains a rod to hold the sensor in the duct, a flange to secure the sensor rod to the duct wall and fill the hole and a gasket to prevent air from leaking through the duct wall. There are five (5) kits in each bag assembly. See Fig. 2.
The rod has slots for threading the wire to prevent loose or hanging wire in the duct and can be adjusted for 6 to 12 inch length. The flange has extended relief for ease of mounting. See Fig. 3.

NOTE:
When using the Sylkbus sensors there will be a slight delay while the Jade controller and the sensor communicate. Analog sensors do not communicate on the Sylkbus and output a 20k ohm signal to the Jade controller so the response time is instantaneous.
NOTE:
When using the C7400S (Sylk bus enthalpy) sensor there is an operation that will allow test of the operation of the W7220 economizer when the outdoor air conditions (temperature and humidity) are too high for economizing.

63-2700–11
JADETM ECONOMIZER MODULE
1. Remove the C7250A dry bulb sensor from the OAT terminals IF you are using
temperature only economizing change over.
2. If you are using enthalpy change over and have a C7400S sensor with a date
code prior to 1301, remove the sensor and replace it with one with a date code
after 1301.
3. Connect a C7400S Sylk bus sensor to the S-Bus terminals (brown colored) on
the W7220A Jade using 18 AWG to 22 AWG solid or stranded wires.
4. Check the STATUS screen for actual outdoor air (OA) temperature and OA
humidity readings.
5. Change the 3-position DIP switch on the C7400S sensor from 1 OFF, 2 OFF, 3
OFF to 1 ON, 2 ON, 3 ON position and immediately back to 1 OFF, 2 OFF 3 OFF
position.
6. The output of the C7400S sensor to the W7220A will be 40 ºF and 40 %RH
which will allow the economizer to go into free cooling mode (economizing
available).
7. Make sure you have 24 Vac on terminal Y1 In to simulate a call for
cooling.
8. After 15 minutes the C7400S sensor will change back to the actual OA
temperature and humidity.
NOTE: If you removed a dry bulb sensor, remove the C7400S from the S-bus
terminals and replace the OAT sensor onto the OAT terminals.
Actuator Wiring Options:
1. The JADE economizer controller can only have one (1) communicating
actuator connected to it.
2. Up to four (4) non-communicating and two (2) 2position actuators (1 each
on EXH1 and AUX1 O)
3. One (1) communicating and up to four (4) non-communicating and two (2)
2-position actuators (1 each on EXH1 and AUX1 O). When using a 2-position
actuator on the AUX1 O, the AUX1 O must be programmed for Exh2 and the % open
is the % open of the outdoor damper when the 2-pos actuator opens. Connect 24
V to Exh1 and/or AUX1 O and ground to the Jade “C” terminal.
CO2 Sensor Wiring
When using the C7232 Honeywell CO2 sensors the black and brown common wires
are internally connected and only one is connected to “IAQ COM” on the Jade.
Use the power from the Jade to power the CO2 sensor OR make sure the ground
for the power supplies are common. See wiring diagram below for the C7232 and
C7632 wiring diagrams.
NOTE:
When using the C7632 (or any 0-10 Vdc CO2 sensor) with the Jade you will need to set the CO2ZERO to 400 ppm and the CO2SPAN to 1600 ppm in the ADVANCED SETUP menu.
NOTE:
When using the TR40 CO2 sensor set the address on the TR40-CO2 to 6. Only one TR40 CO2 sensor can be used with the Jade economizer controller. Address 6 is for a CO2 sensor, address 11 is for a communicating actuator.

IMPORTANT
Table 5 on page 19 illustrates the complete hierarchy. Your menu parameters
will be different depending on your configuration.
For example if you do not have a DCV (CO2) sensor, then none of the DCV parameters appear and only MIN POS will display. If you have a CO2 sensor, the DCV MIN and DCV MAX will appear AND if you have 2 speed fan DCV MIN (high and low speed) and DCV MAX (high and low speed will appear).
SETUP AND CONFIGURATION
Before being placed into service, the JADETM Economizer module must be setup
and configured for the installed system.
IMPORTANT During setup, the Economizer module is live at all times.
The setup process uses a hierarchical menu structure that is easy to use. You
press the and arrow buttons to move forward and backward through the menus and
press the button to select and confirm setup item changes.
Time-out and Screensaver
When no buttons have been pressed for 10 minutes, the LCD displays a screen
saver, which cycles through the Status items. Each Status items displays in
turn and cycles to the next item after 5 seconds.

Alarms if the actuator becomes disconnected from the damper or is slipping on the shaft. If Enabled, the Jade system will complete a system air temperature check. If there is the expected change in system air temperature, then Jade assumes the actuator is connected to the damper.

Low, Standard or High
Sensitivity can be set to HIGH, STANDARD or LOW. High means the system will check 5 times for the damper to move before displaying the alarm. Standard is 10 times before the alarm is displayed. Low is 20 times before the alarm is displayed. Found on the economizer page of the Trade version.

DAMPER AIA THRESHOLD
15 degrees 5 to 40 degrees
Damper threshold feature (Adaptive Integral Action) is the difference in the mixed air temperature reported by the MAT sensor and the MAT setpoint. Lower (2 degrees) transfer rate between the actual MAT sensor reading and the MAT setpoint normally means the damper is closing and opening faster. Larger transfer rate (up to 20 degrees) between the sensor reading and the setpoint normally means the damper is opening and closing slower. Used in applications where there is a large MA space or there is a long duct between the OA and the MA causing a delay. Found on the economizer page of the Trade version.

Enthalpy Settings
When the OA temperature, enthalpy and dew point are below the respective
setpoints, the Outdoor Air can be used for economizing. Fig. 22 shows the new
single enthalpy boundaries in the W7220. There are 5 boundaries (setpoints ES1
through ES5), which are defined by dry bulb temperature, enthalpy and dew
point.
Refer to Table 15 for the ENTH CURVE setpoint values.
To use enthalpy the W7220 must have a C7400S Sylkbus sensor for OA. The W7220
calculates the enthalpy and dew point using the OA temperature and humidity
input from the OA sensor. When the OA temperature, OA humidity and OA dew
point are all below the selected boundary, the economizer sets the economizing
mode to YES, economizing is available.
The later versions of the W7220 Jade controller have the capability to work with a system using a 2-speed supply fan. The W7220 does not control the supply directly but uses the following input status to determine the speed of the supply fan and controls the OA damper to the required position.
OCC Y1 Y2 W
State
Low Low High High
Fan Speed
The W (heating mode) is not controlled by the W7220 but it requires the status to know where to position the OA damper for minimum position for the fan speed.
When conditions are above the selected boundary, the conditions are not good
to economize and the mode is set to NO.
Fig. 22 shows the 5 current boundaries. There is also a high limit boundary
for differential enthalpy. The high limit boundary is ES1 when there are no
stages of mechanical cooling energized and HL when a compressor stage is
energized.
The 2 speed fan delay is available when the system is programmed for 2 speed fan (in the System Setup menu item). The 2 speed fan delay is defaulted to 5 minutes and can be changed in the Advanced Setup menu item. When the unit has a call for Y1 In and in the free cooling mode and there is a call for Y2 In, the 2-speed fan delay starts and the OA damper will modulate 100% open, the supply fan should be set to high speed by the unit controller. After the delay one of two actions will happen:
Table 15 provides the values for each boundary limit.
· The Y2 In call will be satisfied with the damper 100% open and fan on high speed and the call will turn off

OR · If the call for additional cooling in the space has not
been satisfied then the first stage of mechanical cooling will be enabled
through Y1 Out or Y2 Out.
CHECKOUT
Inspect all wiring connections at the Economizer module’s terminals, and
verify compliance with the installation wiring diagrams.
For checkout, review the Status of each configured parameter and perform the
Checkout tests.
NOTE: See “Interface Overview” on page 18. for information about menu
navigation and use of the keypad.
WARNING
Electrical Shock Hazard. Can cause severe injury, death or property damage.
Disconnect power supply before beginning wiring or making wiring connections,
to prevent electrical shock or equipment damage. If any wiring changes are
required, first be sure to remove power from the Economizer module before
starting work. Pay particular attention to verifying the power connection (24
Vac).
Power Up
After the module is mounted and wired, apply power.
Initial Menu Display
On initial start up, Honeywell displays on the first line and Economizer W7220
on the second line. After a brief pause, the revision of the software appears
on the first line and the second line will be blank.
Power Loss (Outage or Brownout)
All setpoints and advanced settings are restoreda after any power loss or
interruption.
a All settings are stored in non-volatile flash memory.
Status
Use the Status menu (see Table 5) to check the parameter values for the
various devices and sensors configured.
NOTE: See “Interface Overview” on page 18. for information about menu
navigation and use of the keypad.
Checkout Tests
Use the Checkout menu (Table 5) to test the damper operation and any
configured outputs. Only items that are configured are shown in the Checkout
menu.
NOTE: See “Interface Overview” on page 18. for information about menu
navigation and use of the keypad.
To perform a Checkout test: 1. Scroll to the desired test in the Checkout menu
using the and buttons. 2. Press the button to select the item. 3. RUN? appears
on the display. 4. Press the button to start the test. 5. The unit pauses and
then displays IN PROGRESS. 6. When all parameters have been tested, press the
button (Menu up) to end the test (e.g. turn off the relay).
The checkout tests can all be performed at the time of installation or any
time during the operation of the system as a test that the system is operable.
CAUTION
Equipment damage may result. Be sure to allow enough time for compressor
startup and shutdown between checkout tests so that you do not short-cycle the
compressors.

TROUBLESHOOTING
Alarms
The Economizer module provides alarm messages that display on the 2-line LCD.
NOTE:
Upon power up, the module waits 60 minutes before checking for alarms. This allows time for all the configured devices (e.g. sensors, actuator) to become operational. The exception is the MA sensor which will alarm immediately.
If one or more alarms are present and there has been no keypad activity for at least 5 minutes, the Alarms menu displays and cycles through the active alarms.
You can also navigate to the Alarms menu at any time.
Clearing Alarms
Once the alarm has been identified and the cause has been removed (e.g.
replaced faulty sensor), the alarm can be cleared from the display.
To clear an alarm, perform the following: 1. Navigate to the desired alarm. 2.
Press the button.
3. ERASE? displays. 4. Press the button.
5. ALARM ERASED displays.
6. Press the
button (MenuUp/Exit) to complete
the action and return to the previous menu.
NOTE: If an the alarm still exists after you clear it, it redisplays within 5 seconds.
