To Install Thermostat and Main Control
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.

Turn off power to the heating and cooling system by removing the fuse or switching off the appropriate circuit breaker. (120 VAC and 12VDC).
Mount main control box to the mounting template using four screws.
Remove three screws from the main control box, allowing the bottom section to hinge open. Control board is now visible and accessible.
Route the 115 VAC power cord through the strain relief of the control box. Tighten the strain relief, making sure not to damage the wires.
Using provided wire connectors, connect line to black, neutral to white, and ground to green.
Using electrical tape or wire nuts, secure the connectors to prevent any potential movement due to vehicle vibration.
Route the 6 pin connector through the opening of the hemmed strain relief of the control box. Mate 6 pin connector to the control box’s wire harness.
Mate the thermistors to the corresponding interconnects on the main board. These will be bundled with the 6-pin connector in the rooftop unit.
For ARC models, one connection will need to be made (indoor coil sensor). For ARH models, an additional connection will need to be made (ambient/ outdoor coil sensors).
Using provided wire connectors, connect 2 furnace wires (blue), 3 thermostat wires (red, yellow, black), and two 12 VDC battery wires (red and black).
Rotate lower section of control box upwards making sure not to crush any wires. Drive three screws, securing he control box closed. The main control install is now complete.
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).
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.
With the base level, mark the placement of the mounting holes.
Ensure no other wires are affected by the drilling of 1/8” holes.
Using a 1/8” drill bit, drill pilot holes in the locations you have marked for the wood screws.
Align thermostat base with mounting holes and feed the control wires through the wire opening.
To Install Thermostat and Main Control (continued)
Use supplied screws to mount thermostat base to wall.
Insert stripped, labeled wires in matching wire terminals and tighten terminal screws once properly aligned. See the “Wiring Diagrams” section of this manual.
CAUTION Make sure exposed portion of wires does not touch other wires.
Gently tug each wire to be sure of proper connection. Verify that each wire is connected to the proper terminal.
For Heat Pump models (ARH15AAC_), flip switch #1 to the on position (reference figure on page 12).
Reattach the thermostat cover by aligning the cover and snapping the bottom in place.
Turn on power to the system at the main service panel.
Test thermostat operation as described in the “Testing the thermostat” section.

Controls and Operating Functions

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 temperature 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 are expected.
In Furnace mode, the RV’s furnace will operate to raise the RV temperature to the setpoint.

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 been reached.

been reached.

Temperature Selection Buttons
Use these buttons to raise and lower the desired setpoint temperature.
LCD Display
Displays operating mode, temperature setpoint, and fan speed.

On Board Diagnostics

Minimum Off Time:
To minimize short cycling, after the compressor shuts off, it cannot restart until 3 minutes have passed.
Freeze-up Prevention:
In COOLING Mode, the display will flash a snowflake symbol to indicate the indoor 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.
Low Voltage Detection:
If the 12VDC drops below 10.5, the thermostat will switch to “OFF” mode and the display will flash “Lo”.
When voltage exceeds 10.5V, the display will stop flashing, show “Lo”, remain in “OFF” mode, and other modes must be reselected by the user.
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.
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.
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.
