Power Up
After the module is mounted and wired, apply power.
Power Loss (Outage or Brownout)
a
All setpoints and advanced settings are restored after any
power loss or interruption.
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.
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.
Initial Menu Display
TROUBLESHOOTING
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.
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.
You can also navigate to the Alarms menu at any time.
a
All settings are stored in non-volatile flash memory.

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 discon-
nected 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.

tings and configuration.
2.

When AUX1 O is set to SYS and there is any alarm (e.g., failed sensors,
etc.), the AUX1 O terminal has 24 Vac out and the LCD displays the

This alarm is only displayed when a communicating actuator is used. (ex:
MS3105AJ)

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.

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
economizer and black motor.
Do I need to change the motor? M7215 motors are used with the W7212 economizers. So if you have one of these units, you
will not have to change the motor.
Wiring
I have 4 terminals on my
actuator and the wiring only
shows 3 wires.
The economizer 24 Vac COM can be wired to the Honeywell actuator common (
TR1). The actuators have internal ground circuits.

Yes, the economizer must be wired to earth ground.
