Return Air (RA) Sylkbus sensor can be added to the system
for differential enthalpy changeover.
This document describes wiring, power up, basic
troubleshooting, and common installation issues for the
JADE™ Economizer Module (Model W7220). For further
information on mounting and operation, refer to Honeywell
document 63-2700.
BEFORE INSTALLATION
Review the following before installing the The W7220:
Electrical
Rated Voltage: 20 to 30 Vac RMS; 50/60 Hz
Transformer: 100 VA maximum system input
Relay Digital Output Rating: 30 Vac
IMPORTANT
All inputs and outputs must be Class 2 wiring.
Inputs
A Mixed air (MA) analog sensor is required on all W7220
units; either an OA (Outdoor Air) sensor for dry bulb change
over or an OA Sylkbus sensor for outdoor enthalpy change
DCV (CO
) Sensor (C7232): 2-10 Vdc control signal;
2
minimum impedance >50k ohm.
Outputs
Actuator signal: 2-10 Vdc; minimum actuator impedance is
2k ohm; Sylkbus two-wire output for Honeywell Sylkbus
communicating actuators.
Exhaust fan, Y1, Y2 and AUX1 O: Contact closure (24 Vac)
All Relay Outputs (at 30 Vac):
Running: 1.5A maximum
Inrush: 7.5A maximum

JADE™ ECONOMIZER MODULE
WARNING
CAUTION
INSTALLATION AND SETUP
The Economizer module may be mounted in any orientation.
However, mounting in the orientation shown above permits
proper viewing of the LCD display and use of the keypad.
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.
WIRING
All wiring must comply with applicable electrical codes and
ordinances, or as specified on installation wiring diagrams.
Module wiring in the field is terminated to the four screw
terminal blocks located on the left and right sides.
Module wiring at the OEM factory is terminated via the header
pin terminals located on the left and right sides. The header
terminal pins and the terminal blocks have common
terminations for the appropriate input or output. The part
number for the OEM female mating connector is 0039973997.
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.
Equipment Damage Hazard.
Electrostatic discharge can short equipment
circuitry.
Ensure that you are properly grounded before
handling the unit.
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.
NOTE: All wiring is polarity insensitive.
Refer to Fig. 1 through Fig. 6 for common wiring
configurations.
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 (2) 2-position
actuators (1 each on EXH1 and AUX1 O)
3. One (1) communicating and up to four (4) non-communicating and (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.

Power Up
After the module is mounted and wired, apply power.
Power Up Delay
Upon power up (or after a power outage or brownout), the
W7220 controller module begins a 5 minute power up delay
before enabling mechanical cooling.
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.
NOTE: If power goes below 18 Vac, the W7220 controller
module assumes a power loss and the 5 minute
power up delay will become functional when
power returns above 18 Vac.
TROUBLESHOOTING
Alarms
The Economizer module provides alarm messages that
display on the 2-line LCD.
NOTE: Upon power up, the module waits several sec-

onds before checking for alarms. This allows
time for all the configured devices (e.g. sensors,
actuator) to become operational. 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.

To clear an alarm, perform the following:
1. Navigate to the desired alarm.
2. Press the

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 alarm still exists after you clear it, it re-dis-
plays within 5 seconds.
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.
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.

COMMON INSTALLATION ISSUES AND CONCERNS
Table 3. Installation Issues and Concerns.
AreaIssue or ConcernPossible Cause and Remedy
ConfigurationAre the old sensors in the unit
(C7400A, C7150 or C7232)
compatible with the economizer
controller?
The unit has a W7459
economizer and black motor.
Do I need to change the motor?
WiringI have 4 terminals on my
actuator and the wiring only
shows 3 wires.
There is an Earth Ground
terminal. Do I need to wire to
earth ground?
What are the part numbers of
the 2 and 6 pin side
connectors?
No, the C7400A and C7150 sensors are not compatible with the W7220. The enthalpy sensor
for the W7220 is the C7400S. The Mixed Air or Outdoor air dry bulb sensors are the C7250A.
The C7232 CO
If you have a W7459 economizer with a M7415 motor you will need to change to a M7215
motor. The W7220 has a 2 to 10 Vdc out to the motor, so you will need a M7215 motor. The
M7215 motors are used with the W7212 economizers. So if you have one of these units, you
will not have to change the motor.
The economizer 24 Vac COM can be wired to the Honeywell actuator common ( or
TR1). The actuators have internal ground circuits.
Yes, the economizer must be wired to earth ground.

The mixed air temperature is the temperature of air that you want to supply to the space. In a
commercial building, this is between 50 to 55°F (10 to 13°C). The mixed air is the mixing of
the return air and the outdoor air.

How do I set my minimum

The minimum position is set using the VENTMIN and VENTMAX setup in the SETPOINTS
menu. VENTMIN is the minimum ventilation required when using an occupancy sensor and
VENTMAX is the minimum ventilation when not using an occupancy sensor for Demand
