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 button
- 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
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 modeis 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 | 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 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 unithas a
call for Y1 Inand in the free cooling mode and there is acall 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.
- IN THIS CONFIGURATION, AN OPTIONAL DISCHARGE AIR TEWHUMIDITY (ENTHALPY) SYLKBUS SENSOR CAN BE ADDED FOR ADVANCED CONTROL AS SHOWN IN THE LOWER LEFT OF THIS FIGURE.
- THE S-BUS COMPONENTS MAY BE DAISY CHAINED TO ANOTHER S-BUS COMPONENT.
- WHEN USING A HEAT PUMP THERMOSTAT, THERMOSTAT TERMINALS MAY DIFFER: W1 MAY BE LABELED O OR B AND W2 MAY BE LABELED W.
- WHEN USING A HEAT PUMP WITH DEFROST FEEDBACK, ADD AN ISOLATION RELAY BETWEEN O AND C.

Notes:
-
Unit wiring shown as reference only. Check unit wiring for actual unit wiring.
-
Standard connection shown. When this econornizer is used in conjunction with a commercial themostat that has an OCC connection, unplug white wire with insulated terminal from pin # 1 and plug into white wire from pin# 7. Connect the thermostat OCC output to A1 terminal on the unitlow voltage terminal board. (On older models without A1 terminal connection afield supplied wire can be routed and connected to the unplugged white wire from Pin #1 to JADE OCC)
-
Economizer pin location $1-2 connected to the following:
Package GaslElectics – “W1” or Gas valve
Package Ar Condifoners – “W1”
Package Heat Pumps – “0” for Cooling mode of operation -
For mechanical cooling (compressor) to energize during economizer cooling mode of operation, a thermostat “Y2” call must be present. A 2 stage cooling thermostat s required for this operation.
