Duo Therm Instructions

A Duo Therm system helps regulate RV temperature rain or shine.

RVs have the moniker "mobile homes" for a reason. They offer many of the comforts of a traditional house such as furniture, plumbing, appliances and HVAC systems. Knowing how to properly operate your RV's HVAC system can help keep you comfortable at rest or on the go. The Duo Therm line of HVAC systems from Dometic works in much the same way as a conventional home HVAC system. With right steps, you can operate a Duo Therm system to help keep your RV comfortable.

Things You'll Need

• RV
• Duo Therm HVAC system
• Duo Therm thermostat

Instructions

Cooling

1. Slide the Temperature Set lever at the right of the thermostat to the desired temperature, from approximately 40 to 90 degrees F.

2. Select your preferred fan speed setting by moving the switch at the bottom center of the thermostat to "Hi" or "Lo." Use Hi to cool and dehumidify the RV interior. Use Lo to maintain the current temperature.

3. Adjust the Fan switch at the upper center of the thermostat to "On" or "Auto." Use On to continuously circulate air. Use Auto to activate the AC system only when the RV's air temperature rises above the set temperature.

4. Set the System switch at the left of the front of the thermostat to "Cool" or "Off." Selet Cool to activate the AC system. Select Off to deactivate the AC system.

Heating

1. Set the desired temperature, fan setting and fan speed in the same manner as activating the AC system.

2. Adjust the System switch to the "Furnace" setting to activate the heating system.

3. Adjust the System switch to "Heat Strip" or "Heat Pump" if the system has these options and you wish to activate them.
