INSTALLATION INSTRUCTIONS
D.
Wiring Requirements
1. Route a copper, with ground, 120 Vac supply
wire from the time delay fuse or circuit breaker
box to the roof opening. Use a listed/certified
non metallic - sheathed single strand cable. See
"A. Table - Unit Data" on page (4).
a. This supply wire must be located in the front
portion of the roof opening.
b. The power MUST be on an appropriately
sized separate time delay fuse or circuit
breaker. See "A. Table - Unit Data" on page
(4).
c. Make sure that at least 15" of supply wire
extends into the roof opening This ensures
an easy connection at the junction box.
d. Protect the wire where it passes into the
opening with approved method.
2. Route a dedicated 12 Vdc supply wire (18-22
AWG) from the RV converter (filtered side) or
battery to the roof opening.
W hen a Comfort Control Center 2 (here-
in-after referred to as CCC 2) thermostat
is being installed with more than 2 zones,
route a dedicated 12 Vdc supply wire (18-
22 AWG) to zone 1 and zone 3 roof open-
ing.
a. This supply wire must be located in the front
portion of the roof opening.
b. Make sure that at least 15" of supply wire
extends into the roof opening.
3. Route a 4 conductor communication cable from
the roof opening to the thermostat mounting lo-
cation using the shortest most direct route. Make
sure that at least 15" of the wire extends into the
roof opening and 6" extends from the wall at the
thermostat mounting location. See "E. Choosing
Thermostat Locations" on page (8).
W hen more than one unit is being installed
(additional zones) with the CCC 2 thermo-
stat, an additional 4 conductor communi-
cation cable MUST be routed to each ad-
ditional unit roof opening. Make sure that
at least 15" of the wire extends into the
roof opening. See (FIG. 26).
4. Route an indoor temperature sensor (optional)
from the roof opening to the indoor temperature
sensor location. The 2 pin connector end goes
to the roof opening. See indoor temperature
sensor installation instructions for proper sensor
location.
5. If system includes a gas furnace, route two 18
gauge thermostat wires from the furnace to the
roof opening of the unit that will control it. If more
than one furnace is to be used, route the second
set of wires to the second unit. Make sure that
at least 15" of the wire extends into the opening.
6. If an Energy Management System (load shed
feature) 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 func-
tion is normally an 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 wire extends into the roof
opening.
7. If an Automatic Generator Start (AGS) kit will be
installed, an additional 4 conductor communica-
tion cable must be routed from the last unit to the
location of the AGS kit. Follow AGS kit instruc-
tions for installation.
E.
Choosing Thermostat Locations
1. If the system is to be used WITHOUT an op-
tional indoor temperature sensor, the proper lo-
cation of the CCC 2 thermostat is very important
to ensure that it will provide a comfortable RV
temperature. Observe the following rules when
selecting a location:
● Locate the thermostat 54" above the floor.
● Install the thermostat on a partition, not on an
outside wall.
● NEVER expose the thermostat to direct heat
from lamps, sun, or other heat producing
items.
● Avoid locations close to doors that lead out-
side, windows, or adjoining outside walls.
● Avoid locations close to supply registers and
the air from them.
2. If the system is be used WITH an optional indoor
temperature sensor, the CCC 2 thermostat may
be mounted anywhere in the RV that is conve-
nient. Avoid hard to reach and hard to see areas.
a. Refer to the instructions provided with the
indoor temperature sensor for details of in-
stallation.

Temperature
Communication Cable Installation.
1. The previously run communication cable (4 con-
ductor telephone cable) must be terminated with
two (2) RJ-11-6C4P telephone connectors. Re-
fer to the crimp tool manufacturer for crimping
instructions. See (FIG. 7) & (FIG. 8).
