10. SYSTEM CONFIGURATION, RESET & CHECKOUT
A. ELECTRONIC CONTROL CONFIGURATION
Depending on the equipment options installed by the recreational vehicle manufacturer, the appropriate dip switches will need
to be switched to the "ON" position. See Fig. 20. Placing the switch in the "ON" position selects that option.
Note: Dip switches are in the "OFF" position when shipped from the factory.
1.
Zone selection - when two or more units are installed and controlled by one Comfort Control Center
TM
, the second unit
becomes Zone 2, the third unit Zone 3, and the fourth unit Zone 4. The appropriate zone dip switch must be set in each
electronic control box for the Zone 2, 3 and 4. See FIG. 20.
2.
Heat Strip selection - For units with a heat strip push the #1 dip switch to the "ON" position. See FIG. 20.
3.
Heat pump models must have the red plug of the outdoor ambient sensor plugged into the RED (P3) plug.
4.
Furnace selection - when a furnace has been connected to a zone, place the furnace dip switch "ON" for that zone.
5.
Differential - differential is the temperature difference between the "ON/OFF" cycle of the thermostat. The normal
differential is preset in the circuit board with the dip switch set to the "OFF" position. In some situations, it may be
necessary to decrease the Differential. The location of the thermostat may create a condition where the normal Differential
will not maintain your comfort zone. If this occurs, the Differential can be shortened by placing the Differential dip switch
in the "ON" position.
Note: Setting the Differential dip switch should only be required when the installation conditions are less than desirable and
is not covered under the limited warranty.
6.
STAGE is not used on these units. Leave in the "OFF" position.
7.
Gen start selection - leave in the "OFF" position.
8.
Replace the unit electrical box cover.
9.
Replace the return air cover.
10. Repeat this procedure for each additional zone.
B. SYSTEM RESET
After setting the dip switches in the electric box, do a system reset. See FIG. 21.
1.
Turn the ON/OFF switch to the "OFF" position.
2.
Simultaneously Depress and hold the MODE and ZONE push-buttons while turning the ON/OFF switch to "ON". FF
should appear in the LCD display until the MODE and ZONE push-buttons are released.
3.
When a dip switch is turned on or off after initial configuration, a system reset will need to be done before the Comfort
Control Center
TM
will recognize the updated selection.
C. SYSTEM CHECKOUT
Verify that all features of the installed system work. Check fan speeds, cooling mode, heat pump mode, furnace (if con-
nected) and heat strip. If the features do not work, check all wiring and confirm that the correct options have been selected
on the Electronic Control Board. See Comfort Control Center™ Operating Instructions.
