Installation Instructions
To Install Thermostat
IMPORTANT: Thermostat installation must conform to
local and national building and electrical codes and
ordinances.
NOTE: Mount the thermostat about five feet above the
floor. Do not mount the thermostat on an outside wall, in
direct sunlight, behind a door or in an area affected by a
vent or duct.
1. Turn off power to the heating and cooling system by
removing the fuse or switching off the appropriate circuit
breaker. (120 VAC and 12VDC).
2. Remove the cover from the base by undoing the
two plastic snaps on the bottom of the base. A small
screwdriver or ballpoint pen can be used to gently
depress one snap at a time. (reference the figure
above).
3. Put thermostat base against the wall where you plan
to mount it. Make sure wires will feed through the wire
opening in the base of the thermostat.
4. With the base level, mark the placement of the mounting
holes.
5 Ensure no other wires are affected by the drilling of 1/8”
holes.
6. Using a 1/8” drill bit, drill pilot holes in the locations you
have marked for the wood screws.
8. Align thermostat base with mounting holes and feed the
control wires through the wire opening.
Apply screwdriver or ballpoint pen
here to open thermostat

Controls and Operating Functions
1. Mode Button
Controls operating mode of the air conditoner. Use this button
to toggle between OFF, Fan only, Cool, Heat Pump, Heat
Pump + Furnace, and Furnace modes.
Only use heat pump mode in conjunction with ARH15AAC*
models (See installation for heat pump models).
In OFF mode, the air conditioner and furnace will not operate.
In Fan Only mode, the fan will operate to circulate air through
the RV.
In Cool mode, the air conditoner will operate to lower the RV
temperature to the setpoint.
In Heat Pump Mode, the unit will operate to raise the RV tem-
perature to the setpoint if the setpoint is within 4°F (2°C) of the
RV temperature.
In Heat Pump + Furnace Mode, If you are beyond a 4°F (2°C)

is recommended for use during night operation or when large
drops in temperature re expected.
In Furnace mode, the RV’s furnace will operate to raise the RV
temperature to the setpoint.
2. Fan Button
Controls operating speed and mode of the fan. Use this button
to toggle between low and high fan speeds.
Use this button to toggle between “FAN ON” and “AUTO FAN”.
In “FAN ON” mode, the fan will run even when the setpoint has

On Board Diagnostics
Ŷ Minimum Off Time:
To minimize short cycling, after the compressor shuts
off, it cannot restart until 3 minutes have passed.
Ŷ Freeze-up Prevention:
In COOLING Mode, the display will flash a snowflake
symbol to indicate the coil is freezing. The compressor
will not operate in this mode. To troubleshoot, it is
recommended to increase airflow by cleaning the filter
and opening the vents.
Ŷ Low Voltage Detection:
If the 12VDC drops below 10.5, the thermostat will
switch to “OFF” mode and the display will show “Lo”.
When voltage exceeds 10.5V, the display will cease
to show “Lo” , remain in “OFF” mode and other modes
must be reselected by the user.
Ŷ Heat Pump Lockout:
In HEAT PUMP Mode, if the outdoor temperature
drops below 32°F (0°C), the display will flash both
the HEAT PUMP icon and 32°F (0°C). During Heat-
Pump Lockout, the unit will not produce heat. When
temperatures below 32°F (0°C) are expected, it is
recommended to use HEAT PUMP+FURNACE Mode
or FURNACE Mode.
Ŷ Heat Pump Defrost:
In HEAT PUMP Mode, if the system detects frost build
up on the outdoor coil, the display will flash the Heat
Pump icon and cease to operate until fully defrosted.
If you are in HEAT PUMP + FURNACE Mode, the
unit will use the furnace until the heat pump is fully
defrosted.

Fault Codes
Ŷ Heat Pump Over Temperature Protection:
In HEAT PUMP Mode, or Heat Pump and Furnace
Mode, if the indoor coil reaches a temperature above
125°F (52°C), the display will flash both the HEAT
PUMP icon and either 99°F or 99°C on the display.
While Over Temperature Protection is activated, the
compressor will not run. It is recommended to increase
airflow by cleaning the filter and opening the vents.
