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:

Navigate to the desired alarm.
Press the button.
ERASE? displays.
Press the button.
ALARM ERASED displays.
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 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 can 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	Fan Speed
OCC	Low
Y1	Low
Y2	High
W	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 the minimum position for the fan speed. The 2-speed fan delay is available when the system is programmed for the 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:

The Y2 In call will be satisfied with the damper 100%open and fan on high speed and the call will turn off
OR
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.

Notes:

Unit wiring shown as a reference only. Check unit wiring for actual unit wiring.
Standard connection shown. When this economizer is used in conjunction with a commercial thermostat that has an OCC connection, unplug white wire with the insulated terminal from pin # 1 and plug into the white wire from pin # 7. Connect the thermostat OCC output to A1 terminal on the unit low voltage terminal board. (On older models without A1 terminal connection a field-supplied wire can be routed and connected to the unplugged white wire from Pin # 1 to JADE OCC)
Economizer pin location S1-2 connected to the following:
Package Gas/Electrics – “W1” or Gas valve
Package Air Conditioners – “W1”
Package Heat Pumps – “O” for Cooling mode of operation
For mechanical cooling (compressor) to energize during the economizer cooling mode of operation, a thermostat “Y2” call must be present. A 2-stage cooling thermostat is required for this operation.
See unit low voltage wiring instruction changes required for economizers equipped with the Honeywell W220 JADE control module and Page 3 of these instructions.
