Comfort Control Center™
The Comfort Control Center is the component that makes
all decisions for operation depending on the system and
the accessories connected to it.
Note:
The PAL tester with the air conditioner Comfort Con-
trol Center Data Capture Module attached will test the in-
tegrity and circuitry of the Comfort Control Center.
If the system is to be used
WITHOUT
a
Remote Tem-
perature Sensor,
the proper location of the Comfort Con-
trol Center is very important to ensure that it will provide a
comfortable RV temperature. Observe the following rules
when selecting a location:
1. Locate the Comfort Control Center 54" above the floor.
2. Install the Comfort Control Center on a partition, no on
an outside wall.
3.
NEVER
expose it to direct heat from lamps, sun or
other heat producing items.
4. Avoid locations close to doors that lead outside, win-
dows or adjoining outside walls.
5. Avoid locations close to supply registers and the air
from them. See Section A7 on page 12.
If the system is to be used
WITH
a
Remote Temperature
Sensor
in
ALL
zones, the Comfort Control Center may be
mounted anywhere that is convenient in the coach. Try to
avoid hard to see areas. See C11 - Remote Sensor and A7
Thermostat Locations.
To check the Comfort Control Center, first verify the DC
power is being supplied and the polarity is correct. This
can be done by plugging the Comfort Control Center com-
munication cable into a standard telephone (RJ-11 type)
jack. Use a VOM meter and read DC volts between red (+)
and black (-). See FIG. C53. If DC power is not present or
reversed polarity, check the communication cable. See
Section C19 on page 52. If DC power is present at the
RJ11 plug on the Comfort Control Center, the next step is
to do a reset procedure. See Section B1d on page 16. If
the Comfort Control Center still does not illuminate or the
display does not read, replace the Comfort Control Center.
If the correct system information does not show, check
configuration - Section D on page 60 before control is re-
placed.
Section C - Components, cont’d.
C19. Cable Assembly
The ten (10) wire cable is used with remote wall mounted
thermostats. It connects the wall mounted thermostat (bi-
metal and electronic thermostat assemblies) to the relay
board.
The cable assembly is available in 15, 25 and 30 foot
lengths. This cable assembly has a male connector on one
end (thermostat connection) and a female connector on
the other end (unit control box).
The cable assembly has 10 wires. The arrow on each con-
nector designates Pin 1.
To check the cable assembly, disconnect each end of the
cable assembly and check for continuity on each wire in
the assembly.
Also, check each connector for bent pins or loose wires.
Each wire has a receptacle that snaps into the connector.
