3.
If a Remote Temperature Sensor is used, the con-
nector 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 open-
ing. Refer to the Remote Sensor Instructions for
details of the installation. See Section E-1.
4.
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 that at least 15" of the furnace thermostat
wires extend into the roof opening.
5.
If an Energy Management System (load shed fea-
ture) 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
normally open relay contact. When the EMS calls
for the compressor to shut off, the relay contacts
should close. Make sure at least 15" of the EMS
wires extend into the roof opening.
6.
Route a 4-conductor control cable from the Comfort
Control Center™ mounting position into the
14-1/4" x 14-1/4" (±1/8") 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™. See
Section E-2.

Installation
1.
Location
a.
If the system is to be used WITHOUT a Re-
mote Temperature Sensor, the proper loca-
tion of the Comfort Control Center™ is very
important to ensure that it will provide a comfort-
able RV temperature. Observe the following
rules when selecting a location:
•
Locate the Comfort Control Center™ 54"
above the floor.
•
Install the Comfort Control Center™ on a
partition, not on an outside wall.
•
NEVER expose it to direct heat from lamps,
sun or other heat producing items.
