3G. DC VOLT REQUIREMENTS
A DC volt supply is required for operation of the Comfort
Control Center. The operating range is 10 to 30 volts DC. If DC
volts are outside of the operating range, you could experience
improper or erratic operation.
DC VOLTS IN EXCESS OF 30 VOLTS CAN CAUSE
DAMAGE TO THE COMPONENTS OF THE SYS-
TEM.
To check DC volts, first check the incoming DC volts between
red (+) positive, and black (—) negative, at the connections on
the electronic control box on rooftop units; or at the connec-
tions at the electric box on basement units.
Next check the output DC volts from the AC power module.
This can be done by using a short telephone communications
line. One end plugged into one of the RJ11 connectors on the
AC power module and the other end plugged into a standard
telephone jack. Next measure the DC volts between red (+)
and black (–). If volts are more at this check, AC ripple is on
the incoming DC source. Be sure DC volts are less than 30.
The AC power module has a filter within the circuitry to filter
any AC ripple and will increase DC volts if AC ripple is present.

4G. COMPONENTS
1. 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 Control
Center Data Capture Module attached will test the integrity
and circuitry of the Comfort Control Center.
If the system is to be used WITHOUT a Remote Temperature
Sensor, the proper location of the Comfort Control Center
is very important to ensure that it will provide a comfortable RV
temperature. Observe the following rules when selecting a
location:
a) Locate the Comfort Control Center 54" above the floor.
b) Install the Comfort Control Center on a partition, not on an
outside wall.
c) NEVER expose it to direct heat from lamps, sun or other
heat producing items.
d) Avoid locations close to doors that lead outside, windows
or adjoining outside walls.
e) Avoid locations close to supply registers and the air from
them.
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.
