DIRECT MOUNT ECONOMIZER OPERATION
GENERAL
This accessory economizer package is designed to save
energy costs by using outdoor air for cooling and
ventilation in place of mechanical cooling whenever
possible. The economizer continuously monitors indoor
and outdoor air conditions and compares them to a
user-selected setpoint to determine if free cooling is
available. The economizer utilizes a fully-modulating
damper actuator, which will control the outside air damper
and return air damper in order to maintain a factory-set
mixed air/discharge air temperature.
ACCESSORIES
(-)XRX-AV04 - Dual Enthalpy Upgrade Kit
For maximum energy savings, this upgrade kit will allow
the economizer to compare the outdoor air enthalpy to the
return air enthalpy, instead of a user-selected setpoint to
determine if "free cooling" is available. This Sylk Bus
Sensor is a combination temperature and humidity sensor
which is powered by and communicates on the two-wire
communication bus of the W7220 economizer logic
module. All OA (Outside Air) and RA (Return Air) sensors
are the same. Sensor must be set for the type of sensing
using the three DIP switches located on the sensor during
INSTALLATION.
Dip Switch Setting C1 C2 C3
Return Air Enthalpy Sensor ON OFF OFF
Outside Air Enthalpy Sensor OFF OFF OFF
(-)XRX-AR02 - Wall-Mounted Carbon Dioxide Sensor
For installations requiring Demand Control Ventilation
(DCV) based upon indoor air levels of carbon dioxide
(CO2). When the unit supply fan is running, the CO2sensor
modulates the outside air damper to maintain a
user-selected CO2level inside the occupied space.
Energy savings are achieved by not bringing in excessive
amounts of outdoor air when the indoor air conditions are
suitable. Energy savings can be substantial on buildings
with highly variable occupancy rates.
NOTE: The (-)XRX-AR02 has a default setting of a 2-10
Vdc output for a 500-1500 ppm CO2input. The W7220
economizer controller requires jumper pins on the
sensor to be relocated to provide a 0-2000 ppm input.

Test of Outdoor Air Enthalpy Sensor
Outdoor air enthalpy sensors with a date code after 1301
can simulate an outdoor air temperature/humidity
condition that forces the W7220A economizer controller
into free cooling mode. If the sensor is from prior to date
code 1301, it can be temporarily replaced with a newer
sensor (Note: There will be a sideways 2 following the part
number on the label as shown in the image below). To
force the controller into economizing mode:
1. Apply power to the unit.
2. Check the STATUS screen on the W7220A for actual
outdoor air (OA) temperature and OA humidity
readings.
3. With power applied to the unit and the C7400S sensor
connected, change the sensor’s 3-position DIP switch
in the order shown below without delay between steps
(from OFF, OFF, OFF to the ON, ON, ON position and
immediately back to OFF, OFF, OFF position). A
stickpin or some other small tool is necessary to move
the DIP switches.
4. The output of the C7400S to the W7220A will be 40°F
and 40% RH which will allow the economizer to go into
free cooling mode (economizing available).
5. By energizing the “G” terminal and “Y1” terminal on the
unit thermostat strip a call for cooling is established
and the economizer response can be observed.
6. After 15 minutes the C7400S sensor will change back
to the actual OA temperature and humidity.

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 8button.
3. ERASE? displays.
4. Press the 8button.
5. ALARM ERASED displays.
6. Press the button Ó(MenuUp/Exit) to complete the action and return to the previous menu.
NOTE: If an alarm still exists after you clear it, it redisplays within 5 seconds.

2. EXH1 SET - Adjustments for (optional) power exhaust.
a. The outside air damper position at which the
power exhaust fan(s) will engage.
b. With 2-speed indoor fan units EXH1 L (low speed
fan) and EXH1 H (high speed fan) settings are
required.
c. Default for EXH1 L is 65% and EXH1 H is 50%.
d. After the outside air damper output command
DAMPER OUT (not ACT POS.) reaches the
power exhaust setpoint, the power exhaust output
EXH1 is energized after a 45 second delay.
e. Range of adjustment is from 0-100% outside air.
e. Single enthalpy strategy: If outdoor air enthalpy is
lower than the ENTH CURVE setpoint, then free
cooling is available.
f. Dual enthalpy strategy: ENTH CURVE Setpoint is
not used. If outdoor air enthalpy is lower than
return air enthalpy, then free cooling is available.
There is also a high limit boundary for dual
enthalpy. The high limit boundary is “ES1” when
there are no stages of mechanical cooling
energized and "HL" when a compressor stage is
energized.
3. EXH2 SET - Adjustments for (optional) 2 speed power
exhaust.
a. The outside air damper position at which the 2nd
speed of the power exhaust fan(s) will engage.
b. With 2-speed indoor fan units EXH2 L (low speed
fan) and EXH2 H (high speed fan) settings are
required.
c. Default for EXH2 L is 80% and EXH2 H is 75%.
d. After the outside air damper output command
DAMPER OUT (not ACT POS.) reaches the
power exhaust setpoint, the power exhaust output
EXH2 is energized after a 45 second delay to
allow the damper to reach the appropriate
position.
e. Range of adjustment is from 0-100% outside air.

4. MIN POS - Outside Air Damper minimum position
a. Displays ONLY if a CO2sensor is NOT connected.
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.
b. Adjust MIN POS to allow the minimum amount of
outdoor air, as required by local codes, to enter the
building.
c. Range of adjustment is from 0-100% (2-10V); in
most applications MIN POS is adjusted to allow
10% to 25% outside air to enter the system.
d. MIN POS can be adjusted at any time.
e. Whenever the “G” (supply fan) signal is present,
the damper will open to this minimum position
unless the mixed air sensor falls below the MA LO
SET (Freeze Protect Mode Setpoint).
5. VENTMAX - Demand Control Ventilation (DCV)
Maximum Setpoint
a. Displays only if a CO2sensor is connected.
b. VENTMAX allows the installer to limit the amount
of outdoor airflow into the building when DCV
overrides the mixed air temperature sensor
setpoint. It is normally equal to the minimum
amount of outdoor air under maximum
occupancy, as required by local codes, to enter
the building.
c. VENTMAX can be adjusted at any time.
6. VENTMIN - Demand Control Ventilation (DCV)
Setpoint
a. Displays only if a CO2sensor is connected.
b. Is the ventilation requirement for less than
maximum occupancy of the space.
c. Compatible CO2sensors will have a 2-10Vdc
output for a 0-2000 ppm CO2input.
d. DCV modulates the outdoor damper between the
VENTMIN and VENTMAX settings to provide
ventilation based on occupancy. The carbon
dioxide (CO2) sensor is used to indirectly monitor
occupancy level.
e. No cooling signal (e.g.Y1, Y2) is required for DCV
to override the outdoor air damper when
ventilation requires outdoor air.
f. The controller must receive a “G” (supply fan)
signal to open the damper.
g. Range of adjustment is from 2 Volts to 10 Volts.
h. VENTMIN can be adjusted at any time.
I. The controller compares the CO2sensor input to
VENT MIN to determine the damper minimum
position.
I. If the actual CO2level is below the setpoint,
then the damper minimum position is
determined by the damper minimum position
(VENTMIN) setting.
ii. If the actual CO2level rises above the
setpoint, then the damper minimum position is
overridden proportionally more open up to the
VENTMAX setting.
iii. If the mixed air temperature drops below 45°F
(MA LO SET - Freeze Protect Mode Setpoint),
the DCV input will be overridden and the
damper may not open.
j. Ensure proper polarity of the sensor wires when
connecting to the economizer controller. Incorrect
polarity negates the sensor signal.
NORMAL OPERATION
1. Fan Only (G)
a. Damper will go to minimum position (in 90
seconds or less) whenever the “G” (supply fan)
signal is present.
b. When “G” signal is removed, the outside air
damper closes against blade seals for tight shutoff
of outside air.
c. If the mixed air temperature drops below 45°F (MA
LO SET Setpoint), then the control will override
the minimum position setting and will modulate the
outside air damper closed.
2. Call for First Stage of Cooling (Y1)
a. Economizer Unavailable (warm outdoor air):
Closes the Y1-O relay (Y1-O) which energizes 1st
stage compressor.
b. Economizer Available (free cooling): The
controller tries to maintain a mixed air temperature
of 53°F ± 5 (MAT SET Setpoint) by modulating the
outside air damper position.
3. Call for Second Stage of Cooling (Y2)
a. Economizer Unavailable (warm outdoor air):
Closes the Y2-O relay (Y2-O) which energizes
2nd stage compressor.
b. Economizer Available (free cooling): Closes the
Y1-O relay (Y1-O) which energizes 1st stage
compressor. The controller tries to maintain a
mixed air temperature of 53°F ± 5 (MAT SET
Setpoint) by modulating the outside air damper
position. After a time period of 2 hours of
simultaneous economizer operation and first
stage compressor operation, the economizer
closes the Y2-O relay (Y2-O) which energizes 2nd
stage compressor.
4. Call for Heat
a. Standard Air Conditioner with electric or gas heat.
(W1 & W2)
I. The Thermostat controls the stages of heating
directly.
ii. If the control detects that the supply fan is on
(through its “G” input), then the control will
open the damper to minimum position.
iii. If the mixed air temperature drops below 45°F
(MA LO SET Setpoint), then the control will
override the minimum position setting and will
modulate the outdoor damper closed.
b. Heat Pump Operation (B)
I. The “B” signal from the Thermostat allows
operation of the compressors to provide
heating without delay.
ii. If the control detects that the supply fan is on
(through its “G” input), then the control can
open the damper to minimum position.
iii. If the mixed air temperature drops below 45°F
(MA LO SET Setpoint), then the control will
override the minimum position setting and will
modulate the outdoor damper closed.

NOTES
1. This economizer requires a two-stage thermostat.
2. When diagnosing the system, the best results are
obtained by first putting the fan setting on the
Thermostat to the “Continuous Fan” mode.
3. Operation of the optional power exhaust only depends
upon the supply fan running and the damper position
(it is possible to set the minimum position high enough
to engage the power exhaust in the heating mode).

b With STG3 DLY in ADVANCED SETUP MENU at 2.0 hours, the 2nd stage of mechanical cooling Y2-O can be energized after a 2 hour delay if the call
for Y1-I and Y2-I have not been satisfied.
cThe CO2sensor has a relay output that is active when the CO2level is above 1200ppm that can be used to energize the indoor fan through the “G”
thermostat input of the unit even if there is not a call for fan, cooling or heating by the room thermostat. Additional field wiring is required to enable this
option.
dAUX2-I is used only on heat pump models to indicate unit is in heat pump (heating) mode.
4. Upon loss of power to the unit or economizer, the
outside air damper will spring close shut in about 5
seconds.
5. The mist eliminator (Permanent Outdoor Air Filter) is of
aluminum mesh construction and should be cleaned
by flushing regularly with warm soapy water. The
replacement mist eliminator size is listed on the first
page of these instructions.
6. Compressor Time Delays, Compressor Interstage
Delays are not provided by the economizer controller.

eUnoccupied Mode is only available by field wiring a normally open (NO) relay in the “G” signal wiring between the unit and economizer. A thermostat
with an occupied output is required which energizes the relay when the space is occupied. The relay interrupts the 24 volt “G” signal from the unit
indoor fan when the space is unoccupied.
