620515, 620525, 620526, 630515 & 630516 Installation Instructions

D.Wiring Requirements

1.120 VAC Supply Line

Route a copper 12 AWG, with ground, 120 VAC supply line from the time delay fuse or circuit breaker box to the roof opening.

a.This supply line must be located in the front portion of the 14-1/4" x 14-1/4" (±1/8") opening.

b.The power MUST be on a separate 20 Amp time delay fuse or HACR circuit breaker.

c.Make sure that at least 15" of supply wire extends into the roof opening. This ensures and easy connection at the junction box.

d.Wiring must comply with all National, State and Local Wiring Codes.

e.Use a steel sleeve and a grommet or equivalent methods to protect the wire where it passes into the opening.

2.Route a dedicated 12 VDC supply line (18-22 AWG) from the RV's converter(filtered terminals) or battery to the roof opening.

a.This supply line must be located in the front portion of the 14-1/4" x 14-1/4" (±1/8") opening.

b.Make sure that at least 15" of supply wire extends into the roof opening.

c.In a multiple zone installation, this wiring is required in only one of the 14-1/4" x 14-1/4" (±1/8") openings.

3.If a Remote Temperature Sensor is used, the con- nector end must be routed from the sensor location to the roof opening of the system which it will control. Make sure that at least 15" of the sensor cable extends into the roof opening. Refer to the Remote Sensor Instructions for details of the installation.

4.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 15" of the furnace thermostat wires extend into the roof opening.

5.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 15" of the EMS wires extend into the roof opening.

6.Route a 4-conductor control cable from the Comfort Control Center™ mounting position into the

14-1/4" x 14-1/4" (±1/8") roof opening. Make sure that at least 15" of the wire extends into the roof opening and 6" extend from the wall at the mounting position of the Comfort Control Center™. See Section E-2.

7.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 15" of the wire extends into the roof opening. See FIG. 27.

8.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.

E.Dometic Comfort Control Center™ & Cable Installation

1.Location

a.If the system is to be used WITHOUT a Re- mote Temperature Sensor, the proper loca- tion of the Comfort Control Center™ is very important to ensure that it will provide a comfort- able RV temperature. Observe the following rules when selecting a location:

•Locate the Comfort Control Center™ 54" above the floor.

•Install the Comfort Control Center™ on a partition, not on an outside wall.

•NEVER expose it to direct heat from lamps, sun or other heat producing items.

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

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

b.If the system is to be used WITH a Remote Temperature Sensor in ALL zones, the Com- fort Control CenterTM may be mounted any- where that is convenient in the coach. Try to avoid hard to reach and hard to see areas.

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

c.A 3/8" diameter hole will be needed to route the cable through the wall. See Section D-3.

2.Control Cable Installation

A 4-conductor control cable must be routed from the roof opening to the Comfort Control CenterTM.

a.Choose the shortest, most direct route from the 14-1/4" x 14-1/4" (±1/8") opening to the Com-

fort Control CenterTMlocationselected.Leave 6" of cable extending through the wall. See Section D-6.

b.The control cable that should be used is a flat, 4-conductor telephone cable.

c.The control cable must be terminated with two

(2) RJ-11-6C4P telephone connectors. Refer to the crimp tool manufacture for crimping instruc- tions. See FIG. 8A, 8B and 8C.
