Enthalpy Set tings
When the OA temperature, enthalpy and dew point arebelow the respective
setpoints, the Outdoor Air can beused for economizing. Fig. 18 shows the new
singleenthalpy boundaries in the W7220. There are 5boundaries (setpoints ES1
through ES5), which aredefined by dry bulb temperature, enthalpy and dew
point.Refer to Table above for the ENTH CURVE setpointvalues.
To use enthalpy the W7220 must have a C7400S Sylkbussensor for OA. The W7220
calculates the enthalpy and dew point using the OA temperature and humidity
inputfrom 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
toYES, 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 Op er a tion
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 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 sat is fied with the damper 100% open and fan on high speed and the call will turn off
OR -
If the call for ad di tional cool ing in the space has not been sat is fied then the first stage of me chan i cal cool ing will be en abled through Y1 Out or Y2 Out.

Notes:1. Unit wiring shown as reference only. Check unit wiring for actual
unit wiring.2. Standard connection shown. When this economizer is used in
conjunction with a commercial thermostat 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 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)3. 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
operation4. For mechanical cooling (compressor) to energize during
economizer cooling mode of operation, a thermostat “Y2” call must be present.
A 2 stage cooling thermostat is required for this operation.5. See unit
low voltage wiring instruction changes required for economizers equipped with
the Honeywell W220 JADE control module and Page 3 of these instructions.
