5.  The 4-/4” x 4-/4” (±/8”) opening is part of the   

 

return air system of the Air Conditioner and must be  

 

 

finished in accordance with NFPA Standard 501C

Section 2.7.

 

6.  Route a dedicated 2 VDC supply line (8-22 AWG)  

 

 

from the RV’s converter or battery to the roof opening.

 

  a.  Wire must be fused at 3 Amps.

 

  b.  This supply line must be located in the front portion  

 

 

  of the 4-/4” (±/8”) opening.

 

  c.  Make sure that at least 5” of supply wire extends  

 

 

  into the roof opening.

 

  d.  In a multiple zone installation, this wiring is    

openings.

 

7.  If a Remote Temperature Sensor is used, the connec- 

 

 

tor end must be routed to the roof opening of the  

 

 

system which it will control. Make sure that at least  

 

 

5” of the sensor cable extends into the roof opening.  

 

 

Refer to the Remote Sensor Instructions for details of  

 

 

the installation.

 

8.  If a furnace is to be controlled by the system, the two  

 

 

furnace thermostat leads must be routed to the roof    

 

opening of the air conditioner that will control it. Make  

 

 

sure that at least 5” of the furnace thermostat wires  

 

 

extend into the roof opening.

 

9.  If an Energy Management System (load shed fea-  

 

ture)  is to be used with the control, two wires must  

 

 

be routed to the roof opening of the zone to be    

 

managed. The signal required for this function is   

 

normally open relay contact. When the EMS calls for  

 

 

the compressor to shut off, the relay contacts should  

 

 

close. Make sure at least 5” of the EMS wires    

 

extend into the roof opening.

 

0. Route a 4-conductor control cable from the  

Comfort Control Center™ mounting position into  

 

 

the 4-/4” (±/8”) roof opening. Make sure that at  

 

 

least 5” of the wire extends into the roof opening and  

 

 

6” extend from the wall at the mounting position of the  

Comfort Control Center™.

 

. In the event that other Air Conditioners are installed  

 

 

(additional zones) an additional 4-conductor control    

 

cable must be routed to the other Air Conditioners.  

 

 

Make sure that at least 5” of the wire extends into  

 

 

the roof opening. (See Fig. 6)

 

2. If an automatic generator start kit (AGS) will be    

 

installed, a 4-conductor control cable must be routed  

 

 

from the last air conditioner to location of AGS kit.  

 

 

Follow AGS kit instructions for installation.

 

.  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 tempera- 

 

 

ture. 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.

 

2.  If the system is to be used WITH a Remote Tem-   

perature Sensor in ALL zones, the Comfort Control  

 

 

Center may be mounted anywhere that is convenient  

 

 

in the coach. Try to avoid hard to reach and hard to  

 

 

see areas.

 

  a.  Refer to the instructions provided with the Re-   

move Temperature Sensor for details of    

 

 

installation.
