a b When values are displayed, pressing and holding the p or q button causes the display to automatically increment.
ERV Operation: When in Cooling mode AND the conditions are NOT OK for economizing – the ERV terminal will be energized. In the Heating mode the cERV 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.
