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.
4) Route a dedicated 12 VDC supply line (18-22
AWG) from the RV's converter or battery to the roof
opening.
a) This supply line must be located in the front
portion of the 14-1/4" 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" open-
ings.
5)
If a Remote Temperature Sensor is used, the
connector end must be routed 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 Instruc-
tions for details of the installation.
6)
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.
7)
If an Energy Management System (load shed
feature) 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.
8)
Route a 4-conductor telephone cable from the
Comfort Control Center™ mounting position into
the 14-1/4" 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™
.
9)
In the event that other Air Conditioners are in-
stalled (additional zones) an additional 4-conduc-
tor telephone cable must be routed to the other Air
Conditioners. Make sure that at least 15" of the
wire extends into the roof opening. (See Page 10,
Fig. 18)
3. DOMETIC COMFORT CONTROL
CENTER™ & CABLE INSTALLATION
A. LOCATION
1) 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 tem-
perature. Observe the following rules when select-
ing a location:
a) Locate the Comfort Control Center™ 54"
above the floor.
b) Install the Comfort Control Center™ on a parti-
tion, 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 out-
side, 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
Temperature 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.
3)
A 3/8" diameter hole will be needed to route the
cable through the wall.
