MOUNTING OUTDOOR TEMPERATURE SENSOR
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.
WIRING CONTROL MODULE
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.
