Note to Installer
l When this economizer is used in conjunction with heat pumps, unit WHITE wire
from economizer plug pin #7 MUST be relocated from defrost control board “T1”
to low voltage terminal board “A1”.
l When this economizer is used with any 2-5 ton package unit (Gas/Electric,
A/C, or Heat Pump) WITHOUT A COMMERCIAL THERMOSTAT, the GREEN wire from
economizer plug pin #1 MUST be relocated from low voltage terminal board “G”
to low voltage terminal board “R” to force dampers to remain in minimum
position 100 percent of the time, while in heating mode, to meet the minimum
fresh air requirements. When used in conjunction with a commercial thermostat,
see Note 2 on wiring diagram.
l Some older 2-5T package heat pumps may not be equipped with a reversing
valve isolation relay, required for use with economizers that have a Jade
control system. Nordyne kit #922598 is required for these applications.

terminal will be energized when the OA is below the ERV OAT setpoint in the
setpoint menu.
After 10 minutes without a command or mode change, the controller will change
to normal operation.
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 5. 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.
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.
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.
a All settings are stored in non-volatile flash memory.
Status
Use the Status Menu to check the parameter values for the various devices and
sensors configured.
Checkout Tests
Use the Checkout Menu to test the damper operation and any configured outputs.
Only items that are configured are shown in the Checkout menu.
To perform a Checkout test:
1. Scroll to the desired test in the Checkout menu using the p and q buttons.
2. Press the 8 button to select the item. 3. RUN? appears on the display.
4. Press the 8 button to start the test. 5. The unit pauses and then displays
TEST RUNNING. 6. Press the button Ó (Menu up) to end the test (e.g. turn
off the relay). Test stops automatically after 10 minutes without a command or
mode change, and will resume normal operation.
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.

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 8 button. 3. ERASE? displays.
4. Press the 8 button. 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.

Enthalpy Settings
When the OA temperature, enthalpy and dew point are below the respective
setpoints, the Outdoor Air can be used for economizing. Fig. 18 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 above 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.
Figure ## 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 table above 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 OCC
Y1 Y2 W
Fan Speed Low Low High 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:
l The Y2 In call will be satisfied with the damper 100% open and fan on high speed and the call will turn off
OR
l 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.
