  7. Using pliers, bend the corner of the control box 

base downward, to create an opening for the sensor 

leads. See Figure 4.

  8. Route the sensor, from the control board, down 

through the opening created in the control box base. 

With wire tie provided, secure the sensor to the 

low voltage wiring or conduit below the control box 

base. Place the wire tie on the sensor wires (not on 

the sensor) and dress so that the temperature sens-

ing area is not in direct contact with any surrounding 

surfaces and is not in direct sunlight.

9A) Cooling Only Air Conditioner Models:

 See Figure 

5 Disconnect the black fan motor lead from the 

contactor (This wire is attached to contactor termi-

nal “T2”, with a quick connect terminal). Reconnect 

this fan motor lead to the black wire from the solid 

state relay on the control module. This wire has a 

sleeved, 1/4" male tab for attaching to the fan motor 

wire terminal.

    Connect the other black wire from the solid state 

relay to the contactor terminal “T2” (from where the 

fan motor lead was disconnected).

    Low voltage wires:

    Connect the 3-pin wire assembly to J5 on the con-

trol board (3-pin male connector).

NOTE: 

To ease the insertion of the connector housing 

onto the J5 header, place the connector on the 

tips of the three header pins.  Angle the connec-

    Connect the yellow lead wire to a 1/4" male tab on 

the right hand side of the main contactor (low volt-

age contactor coil terminal).

    Connect the blue lead wire to the wire nut junction 

of the blue wire.

    Connect the orange wire to the wire nut junction of 

the yellow wire.
