L. CCC 2 System Low Voltage Wire
Connections
Verify the positive (+) 12 Vdc termi-
nal is disconnected from supply battery. Otherwise,
damage to unit could occur.
1. CCC 2 Electronic Control Kit Systems
a. Plug the 6 wire harness into the matching 6
pin connector in the electronic control box.
b. Plug the freeze control sensor into the P5
(Blue or Black) 2 pin matching connector in
the electronic control box.
c. Insert the freeze control sensor into the
evaporator coil ns approximately 1″ above
the bottom of the coil ns and on the left
side. See (FIG. 31). Bend ns over sensor to
secure in place.
2. All Heat Pump Electronic Control Kit Systems
a. Plug the outdoor temperature sensor from
the unit into the P3 (white) 2 pin matching
connector in the electronic control box.
b. Plug the 3 pin connector (reversing valve
wire) from the unit into the 3 pin matching
connector in the electronic control box.
3. All CCC 2 Systems
a. Connect the previously run 12 Vdc supply
wires to the red and black wires protruding
from the roof opening or the red and black
wires in the 6 wire harness at the electron-
ic control box. Connect +12 Vdc to the red
wire; –12 Vdc to the black wire.
b. Connect the previously run furnace thermo-
stat wires (if applicable) to the blue wires
protruding from the roof opening or the blue
wires in the 6 wire harness at the electronic
control box. The polarity of this connection
does not matter.
c. Terminate the 4 conductor communication
cable(s) protruding from the roof opening.
The cable(s) must be terminated with a tele-
phone RJ-11-6C4P connector. Refer to the
crimp tool manufacturer for crimping instruc-
tions.
RJ-11-6C4P connectors MUST be in-
stalled as shown in (FIG. 8) & (FIG. 9).
d. Plug the 4 conductor communication cable
into one of the couplers protruding from the
roof opening or in the electronic control box.
If more than one zone is used, the second
coupler is used to join each addition zone.
2. All Heat Pump Electronic Control Kit Systems
a. Plug the outdoor temperature sensor from
the unit into the white 2 pin matching con-
nector in the electronic control box.
3. All LCD SZ Electronic Control Kit Systems
a. Insert the freeze control sensor into the
evaporator coil ns approximately 1″ above
the bottom of the coil ns and on the left side.
See (FIG. 31). Bend ns over sensor to se-
cure in place.

4. All LCD SZ Systems
a. Connect the previously run +12 Vdc supply
wire to the red wire protruding from the roof
opening or to the red wire at the electronic
control box.
b. Connect the previously run –12 Vdc supply
wire to both the black wire protruding from
the roof opening or to the black wire at the
electronic control box and to the wire of the
three wire cable that goes to the thermostat
12V– terminal.
c. Connect the previously run furnace thermo-
stat wires (if applicable) to the blue wires
protruding from the roof opening or to the
1/4″ connectors at the electronic control box
using the supplied 1/4″ insulated connectors.
The polarity of this connection does not ma-
ter.
d. Connect the red/white wire protruding from
the roof opening or the red/white wire at the
electronic control box to the wire of the three
wire cable that goes to the thermostat 12V+
terminal.
e. Connect the orange wire protruding from the
roof opening or the orange wire at the elec-
tronic control box to the wire of the three wire
cable that goes to the thermostat COMMS
terminal.
