PRODUCT DESCRIPTION
The JADE™ 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.
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
JADE™ 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 wall-mount Sylk bus
TR40 CO2 sensor can be used with the Jade economizer.
PC MOD Tool (optional)
The PC MOD tool is connected to a personal computer and
communicates with the Jade economizer controller via the
Sylk bus. The W7220 PCMOD tool software is free and can be
downloaded from the url in the Accessories section.
Some features on the Jade controller can only be enabled or
disabled using the W7220 PC MOD tool. See the PC MOD
tool options section in Table 5.

MOUNTING
This section describes the mounting procedures for the
JADE™ Economizer module and the sensors.
Economizer Module Location and Mounting
IMPORTANT
Avoid mounting in areas where acid fumes or other
deteriorating vapors can attack the metal parts of the
module’s circuit board, or in areas where escaping
gas or other explosive vapors are present.
IMPORTANT
The module must be mounted in a position that allows
clearance for wiring, servicing, and removal.
Mount the Economizer module on any convenient interior
location using the two mounting holes provided on the
enclosure using #6 or #8 screws (screws are not provided and
must be obtained separately). Use the dimensions in Fig. 1 on
page 3 as a guide.
BEFORE INSTALLATION
Review the “Specifications” on page 2 before installing the The
JADE™ Economizer System.
When Installing This Product
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous condition.
2. Check ratings given in instructions and on the product to
ensure the product is suitable for your application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
NOTE: Jade will be in the "set up" mode for the first 60
minutes after powered. If a sensor for OA air or
Sylkbus device (sensor, actuator) is disconnected
during the set up mode, the Jade will not alarm
that failure. The MA sensor is a system "critical"
sensor, if the MA sensor is removed during the
set up mode, the Jade will alarm. After 60 minutes
the Jade controller will change to operation mode
and all components removed or failed will alarm
in the operation mode.
The Economizer module may be mounted in any orientation.
However, mounting in the orientation shown in Fig. 1 on page 3
permits proper viewing of the LCD display and use of the
keypad.

Economizer Module Wiring Method
Wire the sensors and outputs, then wire the power connection.
Each terminal can accommodate the following gauges of wire:
• Single wire – from 18 AWG to 22 AWG solid or stranded
• Multiple wires – up to two 22 AWG stranded
• For the 24 Vac connections: single wire – from 14 to 18
AWG solid or stranded
• For S-BUS wiring, the sensors may be mounted up to 200
ft. (61 m) from the JADE controller. When the length of wire
is over 100 feet use twisted pair shielded wire.
• All sensor wiring to the Sylk bus and analog sensors is
polarity insensitive.
Prepare wiring for the terminal blocks, as follows:
1. Remove the plastic tabs from the side of the controller
where the connectors will slide onto the PWA.
2. Strip 1/2 in. (13 mm) insulation from the conductor.
3. Cut a single wire to 3/16 in. (5 mm). Insert the wire in the
required terminal location and tighten the screw.
4. If two or more wires are being inserted into one terminal
location, twist the wires together a minimum of three
turns before inserting them to ensure proper electrical
contact. See Fig. 5 on page 6.
5. Cut the twisted end of the wires to 3/16 in. (5 mm) before
inserting them into the terminal and tightening the screw.
6. Pull on each wire in all terminals to check for good
mechanical connection.

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.
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.

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) 2-position
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 CO
sor) with the Jade you will need to set the
CO2ZERO to 400 ppm and the CO2SPAN to
1600 ppm in the ADVANCED SETUP menu.

The economizer will modulate the OA damper to maintain the
mixed air temperature at the setpoint.
Setpoint determines outdoor temperature when the mechanical
cooling cannot be turned on. Commonly referred to as the
Compressor lockout. At or below the setpoint the Y1-O and
Y2-O will not be energized on the controller.
Dry bulb setpoint will only appear if using dry bulb change over.
Setpoint determines where the economizer will assume outdoor
air temperature is good for free cooling; e.g.; at 63 ºF setpoint
unit will economizer at 62 ºF and below and not economize at
64 ºF and above. There is a a 2 ºF deadband.
ES curve will only appear if using enthalpy changeover.
Enthalpy boundary “curves” for economizing using single
enthalpy.
See page 22 for description of enthalpy curves.
Displays ONLY if a CO2 sensor is connected.
Setpoint for Demand Control Ventilation of space. Above the
setpoint, the OA dampers will modulate open to bring in
additional OA to maintain a space ppm level below the setpoint.
With 2-speed fan units MIN POS L (low speed fan) and MIN POS
H (high speed fan) settings are required. Default for MIN POS L
is 3.2V and MIN POS H is 2.8V.
Used for Vbz (ventilation max cfm) setpoint. VENTMAX is the
same setting as MIN POS would be if you did not have the CO2
sensor.
If OA, MA RA and CO2 sensors are connected and DCV CAL
ENABLE is set to AUTO mode, the OA dampers are controlled by
CFM and displays from 100 to 9990 cfm.

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.
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.
Table 15 provides the values for each boundary limit.
Two-Speed Fan Operation
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.
State Fan Speed
OCC Low
Y1 Low
Y2 High
W High
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.
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:
• The Y2 In call will be satisfied with the damper 100% open
OR
• If the call for additional cooling in the space has not been
and fan on high speed and the call will turn off
satisfied then the first stage of mechanical cooling will be
enabled through Y1 Out or Y2 Out.

WARNING
CAUTION
CHECKOUT
a
All settings are stored in non-volatile flash memory.
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.
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.
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.
Power Loss (Outage or Brownout)
All setpoints and advanced settings are restoreda after any
power loss or interruption.
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 re-
displays within 5 seconds.
