Installation Instructions

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. (120 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.

Installation Instructions

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.

Installation Instructions

To Install Thermostat and Main Control (continued)

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 (reference 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.

23. Test thermostat operation as described in the

“Testing the thermostat” section.

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 are 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.

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 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.

Ŷ

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.

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.
