if more than four mobile devices are connected with a CT thermostat, the CT thermostat only
remembers pairing information on the four most recent devices paired.

Any mobile devices that were paired with a CT thermostat that undergoes a system initialization
or pair removal, will need to be paired again with the CT thermostat. The app will automatically
remove device pairs from its paired list if it detects that it is no longer paired with the CT thermostat
on a connection attempt. This is indicated by a pop-up message in the app.

See the instructions for performing a CT thermostat factory reset.

MODE DESCRIPTION

A. Cool Mode

In Cool Mode, the system cycles the compressor On and Off based on room air temperature and

temperature set-point on the CT thermostat. The fan turns on rst, followed by the compressor

approximately 2 minutes later. There are three fan speeds in Cool Mode:

● “Low”: Fan operates continuously at low speed. The compressor cycles On and Off.

● “High”: Fan operates continuously at high speed. The compressor cycles On and Off.

● “Auto”: Fan speed varies depending on the difference between the temperature set-point
and room air temperature. The compressor and the fan cycle On and Off with the CT
thermostat.

B. Furnace Mode

There are three fan speeds in Furnace Mode:

● “Low”: Fan operates continuously at low speed.

● “High”: Fan operates continuously at high speed.

● “Auto”: Fan is Off.

If additional indoor air circulation provided by the air conditioner is NOT desired during
Furnace Mode, select “Auto” in Fan Mode to shut the air conditioner fan off. If “Low” or
“High” is selected, the air conditioner fan will continue to operate at the selected speed.

In Furnace Mode the system cycles the RV furnace On and Off based on room air temperature

and temperature set-point on the CT thermostat. CT thermostat can be congured to operate using

an On / Off differential of either 1ºF (-17 °C) or 2ºF (-16.6 °C). This feature is programmed during
the system initialization.

To set the temperature differential, the system must be Off. Press the Down ( ) button and simul­taneously press and hold the / Mode button for three seconds. Press the Up ( ) button to tog­gle between “d1” and “d2”, “d1” for 1ºF (-17 °C) differential and “d2” for 2ºF (-16.6 °C) differential.

C. Heat Pump Mode (Select Models)

In Heat Pump Mode, the system cycles the compressor On and Off based on room air temperature
and temperature set-point on the CT thermostat. When the system calls for heating there will be a
delay of approximately 2 minutes. There are three fan speeds in Heat Pump Mode:

● “Low”: Fan operates continuously at low speed. The compressor cycles On and Off.

● “High”: Fan operates continuously at high speed. The compressor cycles On and Off.

● “Auto”: Fan speed varies depending on the difference between the temperature set-point
and room air temperature. The compressor and the fan will cycle On and Off with the CT

thermostat. Compressor shuts off rst followed by the fan in approximately 15 seconds.

This mode of operation is a customer option usually selected when temperatures are below 70 ºF

and the user needs to warm the living space. This reverses refrigerant ow in the air conditioner,

causing warm air to be dispensed inside rather than cold, and cold air is dispensed outside rather
than warm.

This mode of operation can cause a dilemma where the outside coil, which is now dispensing cold
air, can freeze up due to cold air blowing across the coil mixed with outside temperature. A system
freeze up can render the heat pump inoperable. There is a defrost feature that prevents this from
happening. See "C. Defrost Cycle" on page 23 for more information.

22

MODE DESCRIPTION

D. Heat Strip Mode (Select Models)

In Heat Strip Mode, the system cycles the heat strip On and Off based on room air temperature
and temperature set-point on the CT thermostat. There are three fan speeds in Heat Strip Mode:

● “Low”: Fan operates continuously at low speed. Heat strip cycles On and Off.

● “High”: Fan operates continuously at high speed. Heat strip cycles On and Off.

● “Auto”: Fan operates in low speed and will cycle On and Off with the CT thermostat.

SPECIAL FEATURES

A. Capacitive Touch Interface

The capacitive touch interface provides a clean, modern user interface.

Capacitive touch interface requires skin contact to function, therefore it will NOT work
through gloves, bandages, etc.

Moisture, including wet ngers, on the capacitive touch interface can cause sensors to

become unresponsive until the water evaporates.

B. Compressor Time Delay

A time delay of approximately 2 minutes occurs anytime the compressor is required to begin cool­ing or heat pump cycle.

C. Defrost Cycle

During heat pump operation, if the outside coil begins to freeze up, a defrost cycle is initiated
that temporarily puts the heat pump back into air conditioning mode. This reverses the refrigerant

ow and melts ice forming on the outside coil. Typically this occurs when outside temperatures

are below 42 ºF (5.5 °C) and repeats every 25 minutes of compressor run time. During this cycle
the unit will cease to provide hot air ow temporarily. This is normal and is NOT and indication of
malfunction.

Defrost cycling SHALL continue until measured temperature of the outside sensor is
< 30 ºF (-1 °C) or > 42 ºF (5.5 °C).

D. Low Ambient Heat Pump Lock Out

All heat pumps are constrained to operation at a temperature range determined by outside condi-

tions. Since all heat pumps lose efciency at low outside ambient temperatures, the heat pump

has a lock out feature that prevents Heat Pump Mode of operation when temperatures fall below
30 ºF (-1 °C). If system is set in Auto Mode fan will be turned off. The fan will remain on if the fan
setting is set to Low or High. However, the compressor will not run and there will be no heat func­tion below 30 ºF (-1 °C).

23

SPECIAL FEATURES

E. Power Interruption

In the event power to the air conditioner or control is interrupted, the system will restart with the
previous set-points once power is restored.

F. LCD Error Code

When the system determines one of the faults listed has occurred, an error code displays on the
LCD.

Error Code:

E1 Loss of communication between CT thermostat and module board. LCD will cycle be-

tween E1 and previous mode setting. System will shut down.

E2 Open circuit or out of range Indoor Temperature Sensor. Heating and cooling operation

will be locked out. Fan operation can continue to operate.

E3 Shorted Indoor Temperature Sensor. Heating and cooling operation will be locked out.

Fan operation can continue to operate.

E4 Open circuit or out of range Outdoor Temperature Sensor (select models). Heat Pump

operation will be locked out. Air Conditioner, Fan, and Furnace operation can continue to
operate.

E5 Open Circuit or out of range Freeze Sensor. Air Conditioner mode of operation will be

locked out, but displays the last temperature set-point.

GENERAL INFORMATION

A. Frost Formation

1. On Cooling Coil

a. Frost on a small portion of the coil is not unusual. Under certain conditions, ice may form

on the evaporator coil. This is indicated by very cold output at very low air speed and the

icing can be seen through the air inlet hole with the lter removed. If this should occur,
inspect the lter and clean if dirty. Make sure air vents are open and not obstructed.

Units have a greater tendency to frost when the outside temperature is relatively low.
This may be prevented by adjusting the thermostat control knob to a warmer setting
(counter clockwise). Should frosting continue, operate on any FAN ONLY setting until
the cooling coil is free of frost; then resume normal operation. If frost condition persist,
contact your local service center for assistance.

2. On Outdoor Coil While Heating

a. Operation at low outdoor temperatures causes low coil temperatures. This can result in

ice forming on the outdoor coil in certain conditions. This is indicated by reduced heat
output and could fully stop fan rotation in extreme conditions. To avoid this, the system
controls turn off the compressor if outdoor temperature drops below 42° F (5° C) and
returns heating when the temperature raises 5° F (-15° C).

24

GENERAL INFORMATION

B. Reduce Heat Gain

The ability of this air conditioner to maintain the desired inside temperature depends on the heat
gain of the RV.

Some preventative measures taken by the occupants of the RV can reduce the heat gain and
improve the performance of the air conditioner. During extremely high outdoor temperatures, the
heat gain of the RV may be reduced by:

● Parking the RV in a shaded area

● Using window shades (blinds and/or curtains)

● Keeping windows and doors shut or minimizing usage

● Avoiding the use of heat producing appliances

Operation on High Fan/Cooling mode will give optimum or maximum efciency in high humidity or

high outside temperatures.

Starting the air conditioner early in the morning and giving it a “head start” on the expected high
outdoor ambient will greatly improve its ability to maintain the desired indoor temperature.

For a more permanent solution to high heat gain, accessories like Dometic outdoor patio and win­dow awnings will reduce heat gain by removing the direct sun. They also add a nice area to enjoy

company during the cool of the evening.

C. Disclaimer

The manufacturer of this unit will not be responsible for damage caused by condensation forming
on ceilings, windows, or other surfaces. Air contains water vapor which condenses when tempera­ture of a surface is below Dew point. During normal operation this unit is designed to remove a
certain amount of moisture from the air, depending on the size of the space being conditioned.
Keeping doors and windows closed when this air conditioner is in operation will greatly reduce the
chance of condensation forming on interior surfaces.

MAINTENANCE

A. Thermostat

1. Clean the CT thermostat with a dry soft cloth.



Do NOT spray water directly on CT thermostat. Do NOT use solvents for cleaning.



If a moist soft cloth is needed to clean the CT thermostat surface, the sensors may be­come unresponsive. If this happens, it will be necessary to allow the water enough time
to evaporate for sensors to regain responsiveness.

B. Air Filter

1. Periodically (a minimum of every 2 weeks of operation) remove the air lter located behind the
return air grille and wash it with soap and water, let dry and then reinstall.



NEVER run unit without return air lter in place. This will plug the unit evaporator coil with

dirt and may substantially degrade the performance of the unit over time.

25

MAINTENANCE

C. Return Air Housing

1. Clean housing with a soft cloth dampened with water and a mild detergent.



NEVER use furniture polish, solvents, scouring pads or powders.

D. Fan Motor

1. The blower motor is factory lubricated and requires no service.
