Dometic 39626.506, 39726.506 Control Cable Installation, Comfort Control Center Mounting

INSTALLATION INSTRUCTIONS

B.Route a dedicated DC supply line (18-22 AWG copper conductors) from the Converter or Battery to the unit's electrical box. Connect with wire nuts positive

(+)DC to the red wire; Negative (-) DC to the black wire.

C.Route thermostat wires from the furnace (if applicable) to the electrical box and attached them to the blue wires extending from the main board. The polarity of these connections does not matter.

D.Route the Energy Management System 2 wires (if applicable) to the electrical box and connect them to the yellow wires extending from the main board. The polarity of these wires does not matter.

Note: If yellow wires are not used and a circuit is made between them, the unit will fail to operate.

3.4.2CONTROL CABLE INSTALLATION

A.A 4-conductor flat control cable, must be routed be- tween the Comfort Control Center (CCC) and the elec- trical box. The maximum length of all control cables is seventy-five (75) feet.

B.Select the shortest direct route between Comfort Control Center TM and the electrical box for the sys- tem.

C.A 3/8" diameter hole will be needed to route the con- trol cable through the wall.

D.Leave 6" of cable extending through the wall.

E.The cable that must be used is a 4-conductor flat control cable.

F.The cable must be terminated with two RJ-11 tele- phone connectors. Refer to the crimp tool manufac- turer for crimping instructions. Be sure the cable is installed correctly into the connector before it is crimped. Polarity is important and a standard pre-made telephone cable will not work. Note: RJ-11 connectors must be wired identically on both ends. See FIG. 3.5.

G.Plug the communications cable(s) into one of the telephone jack(s) on the circuit board in the electri- cal box. (It does not matter which one.)

3.4.3COMFORT CONTROL CENTER MOUNTING

A.Location

The proper location of the Comfort Control Center

(CCC)is very important to ensure that it will provide a comfortable RV temperature. Observe the following general rules when selecting a location.

1. Locate the CCC about 54" above the floor;

2. Install CCC on a partition, not on an outside wall; 3. Direct heat from lamps, sun or other heat produc- ing items will cause erratic operation and tem-

peratures;

4.Avoid locations close to doors that lead outside, windows or adjoining outside walls;

5.Avoid locations close to supply registers and the air from them;

6.Never locate CCC in a room that is warmer or cooler than the rest of the coach - such as the kitchen;

7.The major living area is normally a good location. Note: If the system is to be used with a Remote Temperature Sensor, the Comfort Control Center may be mounted anywhere that is convenient in the coach.

8.Try to avoid hard to reach or hard to see areas.

9.Refer to the instructions provided with the Remote Temperature Sensor for details of installation.

B.Comfort Control Center™ Installation

1.Carefully remove the base plate from the Com- fort Control Center™ . This may be accomplished by inserting a small screwdriver under the tab on the bottom edge of the front cover and gently pry- ing. See FIG. 3.6.

2.Insert the control cable through the hole in the base plate and mount the plate to the wall with the two screws provided. Check the alignment to ensure level installation.

3.Install the control cable RJ-11 connector into the back of the Comfort Control Center™ and gen- tly press onto the base plate.

4.If a Remote Temperature Sensor is to be used, the connector end must be routed to the electri cal control box and connected to the color match- ing plug on the relay board.

5.If a furnace is to be controlled by the system, the two furnace thermostat leads must be routed to the electrical control of the air conditioner that will control it. Make sure at least 15" of the furnace thermostat wires extend into the electrical con- trol box.
