Now that the system is installed, it is necessary to configure the elec-

tronics and check all operations.
Refer to the Operating manual for a description of the air conditioner 

operation.

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. 4. Placing the switch in the “ON” position  

 

selects that option.

 

 

.  Route the 20 VAC supply line through the strain    

relief in Electronic box.  Tighten strain relief, mak- 

 

ing sure enough wire is inside electronic box to  

 

connect with unit 20 VAC wire.  Tighten screws on    

strain relief connector being careful not to pinch and    

cut into the insulation on power supply leads.

 

2.  Connect the white to white; black to black; and    

green to green or bare copper wire using appropri-   

mately sized twist wire connectors. Tape the twist  

 

wire connectors to the supply wiring to assure they    

do not vibrate off.  See FIG. 4.

 

3.   Push the wires into the box and tighten the strain    

relief.

 

4.  Install the cover (part of the mounting hardware) with  

 

the one blunt point screw provided.

Note: Dip switches are in the “OFF” position when shipped from the 

factory.

 

.  Zone selection - when two or more units are installed  

 

 

and controlled by one Comfort Control Center, 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 kit for  

 

 

Zone 2, 3 and 4.

 

2.  Furnace selection - when a furnace has been con-   

 

nected to a zone, place the furnace dip switch “ON”  

 

 

for that zone.

 

3.  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 Differen-   

 

tial dip switch to the “ON” position. 

Note: Setting the Differential dip switch should only be required when 

installation conditions are less than desirable and is not covered under 

the limited warranty. 

 

4.  Stage selection - stage is not used on these units.    

 

Leave in the “OFF” position.

 

5.  Gen start selection - leave in the “OFF” position.

 

After  setting the dip switches in the electronic control 

 

kit, do a system reset.

 

.  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 LCD display until the  

 

 

mode and zone push-buttons are released.

3.  When a dip switch is turned on after initial configura-

 

tion, a system reset will need to be done before the    

 

Comfort Control Center will recognize the updated  

 

 

selection.

 

Verify that all features of the installed system work.    

Check fan speeds, cooling mode, furnace (if connected)    

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 Box. See Comfort Control  

Center™ Operating Instructions.
