Installation Instructions

WARNING ELECTRICAL Shock Hazard
Turn off the power by removing the fuse or switching the appropriate circuit breaker to the OFF position before removing the existing thermostat.

Package Contents

• Thermostat on cover
• Thermostat base
• Screws

Tools Required

• Drill with 1/8” bit
• Ballpoint Pen
• Screwdriver

To Remove Existing Thermostat

• Turn off power to the heating and cooling system by removing the fuse or switching off the appropriate circuit breaker (120 VAC and 12VDC)
• Remove the cover of the old thermostat. This should expose the wires.
• Label the existing wires with the wire labels before removing the wires.
• After labeling wires, remove wires from the terminal block.
• Remove the existing thermostat base from the wall.

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 the 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.
7. Align the thermostat base with mounting holes and feed the control wires through the wire opening.
8. Use supplied screws to mount the thermostat base to the wall.
9. Insert stripped, labeled wires in matching wire terminals by pressing on the corresponding terminal contact. See the “Wiring Diagrams” section of this manual.
   CAUTION Make sure the exposed portion of wires does not touch other wires.
10. Gently tug the wire to be sure of proper connection.
    Double-check that each wire is connected to the proper terminal.
11. For Heat Pump models (ARH15AAC*), flip switch #1 to the on position (reference figure on the following page).
12. Replace the cover on the thermostat by aligning the cover and snapping the bottom it in place.
13. Turn on power to the system at the main service panel.
14. Test thermostat operation as described in the “Testing the thermostat” section.

Controls

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 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 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 been reached.
3. Temperature Selection Buttons
   Use these buttons to raise and lower the desired setpoint temperature.
4. 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 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 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.
• 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 buildup 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.

Testing the Thermostat

Once the thermostat is installed, it should be thoroughly tested.
Note: Before testing the thermostat, move the Fan Auto/On switch to the Auto position.
Fan Test

1. Toggle the Mode button to Fan ON position.
2. The fan turns on.
3. Toggle between low and high fan speeds with the FAN button.
4. Speed should adjust accordingly

Cool Test

1. Toggle Mode button until Cool mode is on. Cool mode screen is displayed
2. Adjust set temperature so it is 5 degrees below room temperature.
3. Air conditioning should come on within a few seconds.
4. Adjust the set temperature so it is 2 degrees above the room temperature and the A/C should turn off.
   Note:
   There is a 3 minute time delay and a 3 minute minimum run time for the compressor when it turns on/off.

Furnace Test

1. Toggle mode button until mode is active. Furnace mode screen is displayed.
2. Adjust set temperature so it is 5 degrees above room temperature. Within a few seconds, the furnace should initiate its startup procedure.
3. Adjust the set temperature so it is 2 degrees below the room temperature and the heat should turn off. Note: Depending on the model of furnace used, there may be a delay in engaging and disengaging the furnace.
