THERMOSTAT OPERATING AND WIRING
REQUIREMENTS
The 6636 series air conditioner is designed to be operated
from an RV Products electronic wall mounted thermostat.
See component match-up section for thermostat part number
and description. The thermostat is designed to operate 12
VDC controlled heating and air conditioning systems. The
thermostat must be operated from a 12 VDC power source.
Maximum thermostat output for any load including the
furnace control wire must not exceed one amp.
The thermostat is equipped with a replaceable fast-acting 2
amp fuse located on the base of the thermostat. The fuse is
designed to open if the furnace is mis-wired or there is a short
in the system. Before replacing fuse, the cause of the failure
must be located and corrected.
IMPORTANT
Current draws in excess of one amp or
shorting any thermostat wires will cause
permanent thermostat failure.
The installer must provide the power source used to operate
both the thermostat and its control circuits. This power
source must provide one amp of continuous current at 12
VDC.
The thermostat is pre-wired at RV Products with two quick
connect electrical receptacles. There is one 9 pin receptacle
carrying the control wires required to operate the air
conditioner, and a 3 pin receptacle carrying the two power
supply leads and the one furnace control lead.
The thermostats 9 pin receptacle mates with a receptacle on
one end of the RV Products 35' pre-wired thermostat harness.
See component match-up section for harness part number and
description.
The thermostat harness does not include the wiring for the
3- pin plug. Should the installer desire a total plug in system,
then the mate and pins for this connection must be purchased
separately. Both the receptacle and the pins are manufactured
by AMP (Aircraft Marine Products, Inc., Harrisburg, PA). In
most cases the parts can be obtained through a local supply
house.
The AMP part numbers are:
1)
3 pin male receptacle #7-480700-0
2)
female pin (for male receptacle) #350218-1
10. THERMOSTAT AND 12 VDC WIRING
Should the installer desire to hard wire this connection rather
than purchasing the receptacle, the three pin connector can be
cut from the wire ends, the wires stripped and spliced to
complete the required connections. For further wire
identification and function, reference Chart 2.
When using wire nuts to complete electrical connections,
always apply a U.L. approved electricians tape and secure the
wire nuts to the wires in a workmanlike manner.
THERMOSTAT HARNESS
RV Products produces a pre-wired 35' thermostat wiring
harness for this system. See component match-up section for
harness part number and description. This harness consists
of the wires required for operating the air conditioner and
quick connect receptacles for both the thermostat and the air
conditioner connections.
At the thermostat, the connection is completed with a square
9 pin receptacle that slides together and snap-locks in place.
When making this connection:
1)
verify that the connectors are properly
aligned
2)
do not use excessive force when joining the
connectors
3)
verify that the connectors have snapped
together on both sides.
The thermostat umbilical attaches to the unit with a rain-tight
fitting. To install, remove the ring-nut from the rain-tight
fitting and insert the wire end and fitting into the hole in the
wirebox side. The ring-nut will now slide over the wire end
and reinstall onto the rain-tight fitting threads. Tighten
securely. The wire end plugs into the receptacle on the
wirebox printed circuit board. Insure that the plug "snap-
locks" into the receptacle.
