ROUTING THERMOSTAT WIRING
1.
Following the instructions packed with the
thermostat, determine a location for the thermostat
mounting.
2.
Following Airxcel, Inc. low voltage wiring
specifications and all local and national electrical
codes: For 12 VDC thermostats, it is required that
the thermostat 12 volt negative connection be routed
directly from the converter or battery. It is highly
desirable to provide 12 volt control power from the
battery side of the converter. These precautions
should prevent control problems.
A.
Route the thermostat 12 VDC supply wiring
from the power source to the thermostat
mounting location.
Two wires are required:
One supply lead must be +12 VDC and
red in color.
The second supply lead must be -12 VDC
and blue in color.
B.
To protect the wall mount thermostat from
over-current damage, a 2 amp fuse has been
provided with the thermostat.
C.
Route the thermostat control wiring from the
thermostat mounting location into the front
of the ceiling plenum opening.
