6) Route a copper 12 AWG, with ground, 115 VAC supply
line from the fuse or circuit breaker box to the roof
opening.
a. This supply line must be located in the front portion of
the 14" opening.
b. The power supply MUST be on a separate Time
Delay Fuse or HACR Circuit Breaker.
c. Make sure at least 15" of supply wire extends into the
roof opening. This ensures easy connection at the
Junction Box.
d. Wiring must comply with all National, State and Local
Wiring Codes.
e. Use a steel sleeve and a grommet or equivalent
methods to protect the wire where it passes into the
opening.
7) Route a dedicated 12 VDC supply line (18-22 AWG) from
the RV's Converter or Battery to the roof opening.
a. This supply line must be located in the front portion of
the 14" opening.
b. Make sure that at least 15" of supply wire extends into
the roof opening.
c. In a multiple zone installation, this wiring is
required in only one of the 14" openings.
8) If a Remote Temperature Sensor is to be used, the
connector end must be routed to the roof opening of the
system which it will control. Make sure that at least 15" of
the sensor cable extends into the roof opening.
9) If a furnace is to be controlled by the system, the two
furnace thermostat leads must be routed to the roof
opening of the air conditioner that will control it. Make sure
at least 15" of the furnace thermostat wires extend into
the roof opening.
10) If an Energy Management System- EMS (load shed) is to
be used with the control, two wires must be routed to the
roof opening of the zone to be managed. The
signal required for this function is a nor-
mally open relay contact. when the EMS
calls for the compressor to shut off, the
relay contacts should close. Make sure
that at least 15" of the EMS wires extend
into the roof opening.
11) Route a 4-conductor telephone cable from the Comfort
Control Center™ mounting position into the 14" roof
opening. Make sure that at least 15" of the wire extends
into the roof opening and 6" extend from the wall at the
mounting position of the Comfort Control Center™.
12) In the event that other A/C's are to be installed (additional
zones) an additional 4-conductor telephone cable must be
routed to the other A/C's. Make sure that at least 15" of the
wire extends into each of the roof openings. See FIG. 3.
