SYSTEM CONTROL SWITCH - TEST

Disconnect leads from control switch. Turn control to posi-
tion being tested (see Figure 8). There must be continuity 
as follows:

1.  “Off” Position-no continuity between terminals.

2.  “Lo Cool” Position-between terminals “C” and “3”,  

“C2” and “2”, “LO” and “M/S”, “AR” and “5”.

3.  “Med Cool” Position-between terminals “C” and “3”,  

“C2” and “2”, “M” and “M/S”, “AR” and “5”. 

4.  “Hi Cool” Position-between terminals “C” and “3”,  

“C2” and “2”, “H” and “M/S”, “AR” and “5”.

5.  “Hi Heat” Position-between terminals “C” and “1”,  

“C2” and “4”, “H” and “M/S”, “AR” and “5”.

6.  “Med Heat” Position-between terminals “C” and “1”,  

“C2” and “4”, “M” and “M/S”, “AR” and “5”.

7.  “Lo Cool” Position-between terminals “C” and “1”,  

“C2” and “4”, “LO” and “M/S”, “AR” and “5”.

8.  “Fan Only” Position-between terminals “L1”, “M” 

and “2”.

SYSTEM CONTROL SWITCH

(“WE” & “WY” Models)
An eight position switch is used to regulate the operation 
of the fan motor, compressor and electric heater. 

The unit can be operated in cooling or heating mode with 
the compressor or electric heater on and the fan motor 
operating on low, medium or high speed.

The fan motor can also be operated independently on 
medium speed. See switch section as indicated on 
decorative control panel, in Figure 7.

Wait three minutes before restarting

NOTE:

Units will operate in constant fan in the cooling mode and

Frost Probe Sensor: 

Disables compressor at 35 degrees 

F +/- 3 degrees F

Indoor Probe Sensor: 

Control range is 60 degrees F to 90 

degrees F +/- 2 degrees F

Indoor temperature will be displayed by pressing:

(XQ / WS Units)

 

The

 Fan Speed 

button and the

 Temp Up 

button

.

The indoor temperature will be displayed for 10 seconds.  
The display will change back to the Set Point temperature by 
pressing any key button except for the On/Off button.  The 
indoor temperature can be viewed in all modes, including 
test mode.

Keep Alive

: The electronic control has a memory to retain 

all functions and status as set up by the user in the event 
of a power failure.  Once power is restored to the unit 
there is a two second delay before the fan comes on and 
approximately three minutes delay before the compressor 
is activated, providing that the mode was set for cooling and 
the set point temperature has not been met in the room.
