(see Figure 16)
Disconnect and remove the black lead from the fan
relay (terminal #1) to the unit contactor "T2". Connect
one black lead from the SSR on the Control Module to
the #1 terminal of the fan relay. Connect the other
black lead to the unit contactor "T2" terminal.
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 14. 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). See
Figure 16.
3.
Connect the
blue
lead wire of the harness to the
wire nut junction of the blue wire (use new wire
nuts in kit).
4.
Connect the
orange
wire to the wire nut junction
of the orange wire (use new wire nuts from kit).
See Figure 16.
5.
Connect the Liquid Line Sensor to J2 on the
Control Module. See Figure 14.
6.
Connect the Outdoor Temperature Sensor (Ambi-
