7. Connect Control Module Wires
There are five (5) Control Module wiring configura-
tions. Depending on your configuration continue with
the section that applies.
• 7a. 2/4YC** and 4TC** Single Phase 230 Volt
Cooling and Gas/Electric Models. Go to page 9.
• 7b. 2/4WC** & 4DC** Single Phase 230 Volt
Heat Pump Models. Go to page 10.
• 7c. 2/4YC** and 4TC** Three Phase 230 & 460
Volt Cooling and Gas/Electric Models. Go to page
11.
• 7d. 2/4WC** & 4DC** Three Phase 230 Volt
Heat Pump Models. Go to page 12.
• 7e. 2/4WC** Three Phase 460 Volt Heat Pump
Models. Go to page 13.

Disconnect the black fan motor lead from the
contactor (this wire is attached to contactor terminal
“L2”, with a quick connect terminal). Cut the
terminal off of this wire and strip the end about 1/2
inch. Select one of the black wires from the SSR relay
on the Control Module, cut the terminal off and strip
the end about 1/2 inch. Connect these two (the black
fan motor lead to the black SSR lead) with a wire nut
supplied.
Connect the other black wire from the solid state
relay (SSR) to the contactor terminal “L2” (from
where the fan motor lead was disconnected).
Connect Low voltage wires (BYO):
1. Connect the 3-pin BYO low voltage wire harness
(supplied in kit) to J5 on the Control Module (3-pin
male connector). See Figure 11. Note: to ease the
insertion of the connector housing on to the J5
header, place the connector on the tips of the three
header pins. Angle the connector upward toward
the header latch while pushing connector over the
header pins.
2. Connect the yellow lead wire of the harness to a
¼ " male tab on the right hand side of the main
contactor (low voltage contactor coil terminal).
3. Connect the blue lead wire of the harness to the
wire nut junction of the blue wire (use new wire
nuts from kit).
4. Connect the orange wire to the wire nut junction
of the yellow wire (use new wire nuts from kit).
5. Connect the Liquid Line Sensor to J2 on the Con-
trol Module. See Figure 11 on page 10.
6. Connect the Outdoor Temperature Sensor (Ambi-
ent Sensor) to J3 on the Control Module. See Fig-
ure 11 on page 10.
7. Reinstall louvers and panels. Continue with step 8.
