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.

1. Turn off power to the heating and cooling system by removing the fuse or switching off the appropriate circuit breaker. (115 VAC and 12VDC).
2. Mount main control box to the mounting template using four screws.
3. Remove three screws from the main control box, allowing the bottom section to hinge open. Control board is now visible and accessible.
4. 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.
5. Using provided wire connectors, connect line to black, neutral to white, and ground to green.
6. Using electrical tape or wire nuts, secure the connectors to prevent any potential movement due to vehicle vibration.
7. 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.
8. 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).
9. Using provided wire connectors, connect 2 furnace wires (blue), 3 thermostat wires (red, yellow, black), and two 12 VDC battery wires (red and black).
10. 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.
11. 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 on page 5).
12. 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.
13. With the base level, mark the placement of the mounting holes.
14. Ensure no other wires are affected by the drilling of 1/8” holes.
15. Using a 1/8” drill bit, drill pilot holes in the locations you have marked for the wood screws.
16. Align thermostat base with mounting holes and feed the control wires through the wire opening.
17. Use supplied screws to mount thermostat base to wall.
18. 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.
19. Gently tug each wire to be sure of proper connection. Verfiy that each wire is connected to the proper terminal.
20. For Heat Pump models (ARH15AAC_), flip switch #1 to the “ON” position (see figure on page 12). Additionally, if your unit will not be connected to a furnace, furnace mode can be disabled by toggling switch #4 to the “on” position (see figure on page 12).
21. Reattach the thermostat cover by aligning the cover and snapping the bottom in place.
22. Turn on power to the system at the main service panel.

If Switch #5 is ON (RV-C Virtual T.Stat Method), a RARES1A room sensor kit will be required.

Control and Operating Functions (RAREC2A)

switch 1 specifies default fan speed in HP Mode if GL or  GH is not specified
switch 2 specifies if a “Y” signal is required for HP Mode.

On Board Diagnostics (RARWT_ _)

Low Voltage Detection:

If the 12VDC drops below 10.5V, the thermostat will switch to “OFF” mode and flash “Lo”.
When voltage exceeds 10.5V, the display will show a constant “Lo” and remain in “OFF” mode until a different mode is reselected by the user.

A/C Freeze-Up Prevention:
In COOL mode, a flashing snowflake icon indicates that the indoor coil is near freezing, and that the compressor was turned off.
Recommend increasing airflow by cleaning the filter and opening vents.

Heat-Pump Auto-Defrost:
In HEAT-PUMP modes, a flashing HEAT-PUMP icon indicates that the unit is performing an auto-defrost.
In HEAT-PUMP+FURNACE mode, while auto-defrosting, the unit will use the furnace.

Heat-Pump Lockout:
In HEAT-PUMP ONLY mode, a flashing HEAT-PUMP icon AND 25°F (-4°C) indicates that the outdoor temperature dropped below 25°F (-4°C) and the Heat-Pump is locked out.
Recommended when expecting temperatures below 25°F (-4°C) to use HEAT-PUMP+FURNACE or FURANCE ONLY mode.

On Board Diagnostics (RARWT_ _)

Heat-Pump Over Temperature:
In HEAT-PUMP modes, a flashing HEAT-PUMP icon AND 99°F (99°C) indicates that the indoor coil reached a temperature above 135°F (58°C) and the compressor was shut off.
