Enthalpy Settings

When the OA temperature, enthalpy and dew point are below 
the respective setpoints, the Outdoor Air can be used for 
economizing. Fig. 26 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 11 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.

Fig. 26 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.

Table 11 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.

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 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.

Indoor Air Quality AQ

Indoor Air Quality (indoor sensor input): Terminal AQ accepts a 
+2 to +10 Vdc signal with respect to the (AQ1) terminal. When 
the signal is below it's set point, the actuator is allowed to 
modulate normally in accordance with the enthalpy and mixed 
air sensor inputs. When the AQ signal exceeds it's set point 
setting and there is no call for free cooling, the actuator is 
proportionately modulated from the 2 to 10 Vdc signal, with 2 
Vdc corresponding to full closed and 10 Vdc corresponding to 
full open. When there is no call for free cooling, the damper 
position is limited by the IAQ Max damper position setting. 
When the signal exceeds it's set point (Demand Control 
Ventilation Set Point) setting and there is a call for free cooling, 
the actuator modulates from the minimum position to the full 
open position based on the highest call from either the mixed 
air sensor input or the AQ voltage input.

Phasing

Predator

®

 units are properly phased at the factory. Check for 

proper compressor rotation. If the blower or compressors rotate 
in the wrong direction at start-up, the electrical connection to 
the unit is misphased. Change the phasing of the 

Field Line 

Connection at the factory or field supplied disconnect

 to 

obtain proper rotation. (Scroll compressors operate in only one 
direction. If the scroll is drawing low amperage, has similar 
suction and discharge pressures, or producing a high noise 
level, the scroll is misphased.)

Blower Rotation

Check for proper supply air blower rotation. If the blower is 
rotating backwards, the line voltage at the unit point of power 
connection is misphased (See ‘PHASING’).

Scroll compressors require proper rotation to operate

not change the internal wiring to make the blower
