14.CONFIGURATION
The Comfort Control Center configuration relates to setting
the dip switches and particular components (remote sen-
sor, cold control, furnace, ambient sensor and load man-
agement system) that can be connected to the AC power
module board. The Comfort Control Systems can operate
up to 4 units for one Comfort Control Center (thermostat)
provided the configuration is correct.
Note: If the configuration of the dip switches and other com-
ponents are not correct, the unit could operate erratically or
not at all.
Improper configuration could cause damage
to components of the system.
Configuration is done on the AC power module board, usu-
ally at the time of installation of the unit. Locate the control
box or electric box that contains the AC power module
board.
The configuration for zone 1 is all dip switches
"OFF". All units require
the cold control to be
plugged into the blue P5
connector on the board
and the sensor is in-
serted in the evaporator
coil. If a remote sensor
is used it will be plugged
into the white P4 con-
nector. See FIG. 10
&12.
The Comfort Control
Center requires DC volt-
age to be supplied to the
red (positive +) and
black (negative -) leads
of the control box or
power module.
The control box or power module is
connected to the Comfort Control Center
(wall thermostat) by a telephone type cable. See section
B2. If more than one unit is to be operated off the Comfort
Control Center, a second telephone type cable is needed.
Both telephone cables are plugged into the control box or
power module for the first unit. The second cable is routed
to the control box or power module for the second unit. The
dip switch for zone 2 needs to be turned on. See FIG. 8.
Each additional zone (up to four total zones) requires only
the dip switch for its zone number to be turned on.
If an electric heat strip is to be operated by the Comfort
Control Center, it is plugged into the control box and the
heat strip dip switch is turned to "ON". If a second unit is
equipped with a heat strip, the dip switch for the heat strip is
turned on along with zone 2 dip switch.

If a furnace is operated by the Comfort Control Center, the
thermostat wires are attached to the two (2) blue wires from
the control box. The furnace dip switch for that zone (con-
trol box or power module) is turned on.
If the unit is a heat pump, the ambient sensor for the out-
door temperature is plugged into the red P3 connection. If
more than one unit is used, the zone dip switch must be
turned on.
The two yellow leads on the control box are for use with the
load management system. If the wires are connected or
shorted to each other through the metal of the mounting or
electrical box, the compressor will not operate.
The stage dip switch is used in dual basement heat pumps
or air conditioners. It prevents both compressors from starting
at the same time. The second stage is controlled by a
temperature differential that is set in the Comfort Control
a.Locate the remote sensor 54" above
the floor.
b.Install the remote sensor on a partition, never
on
c. Avoid locations that are close to doors that lead out-
side, windows or outside adjoining walls.
d. Keep away from discharge from supply registers.
e. Place in areas that have good air movement. Avoid
corners and under cupboards.
If the remote sensor is used for all zones, the Comfort Con-
trol Center can be located anywhere that is convenient.
To check the Comfort Control Center, make sure the ON/
OFF switch is in the ON position. Check for DC voltage
(10-16 VDC) to the CCC and that the polarity is correct. If
the previously mentioned items are correct then do a reset
on the CCC.
NOTE: When the Comfort Control Center is set to operate
the heat strip or heat pump, the fan will operate in the low
speed only the Auto fan mode. NEVER MIX 4 button cir-
cuit boards and Comfort Control Centers with the 5
button circuit boards and Comfort Control Center.

CONTROL CENTER
The Comfort Control
Center is the compo-
nent that makes all
the decisions for op-
eration depending on
the system and the
accessories con-
nected to it.
The location of the
Comfort Control Cen-
ter is very important if it
is being used without a re-
mote sensor. Use the following
guidelines for the location:
an outside wall.
