5. Installation
5.1. Preparing for Installation
- Disconnect Power: Before beginning, ensure all power to your RV's heating and cooling system is completely disconnected at the circuit breaker or fuse panel.
- Remove Old Thermostat: Carefully remove the cover of your existing thermostat. Note the wiring connections before disconnecting them. It is recommended to take a photograph of the wiring for reference.
- Verify Compatibility: This thermostat is an OEM replacement for the Duo-Therm 3106995.032. It requires an existing analog control board and will not function with heat pump or heat strip systems. To ensure proper fit, remove the air distribution box from your unit and check for a small metal box. If this box reads part number 3107541.009, this product is the correct replacement.
5.2. Wiring Diagram
Connect the wires from your RV to the corresponding terminals on the new Dometic thermostat. Refer to the wiring diagram below and your old thermostat's wiring for accurate connections. Typically, RV thermostats use 6-wire analog control.
5.3. Mounting the Thermostat
- Position the new thermostat base plate against the wall, aligning it with the existing mounting holes if possible.
- Use the provided mounting screws and wall anchors to secure the thermostat base plate firmly to the wall.
- Once the wiring is complete and the base plate is secure, carefully attach the front cover of the thermostat.
- Restore power to the RV's heating and cooling system.

Operating your Dometic analog thermostat is straightforward:
6.1. System Modes
- COOL: Activates the air conditioning system to cool the RV interior.
- OFF: Turns off both heating and cooling systems.
- FURNACE: Activates the furnace to heat the RV interior.
6.2. Fan Settings
- ON: The fan will run continuously, regardless of whether the heating or cooling system is active.
- AUTO: The fan will only operate when the heating or cooling system is actively running to reach the set temperature.
- HI/LO: Adjusts the fan speed. Select HI for maximum airflow or LO for quieter operation and reduced airflow.
6.3. Temperature Adjustment

8. Troubleshooting
If you encounter issues with your Dometic thermostat, consider the following common troubleshooting steps:
- No Power: Check the RV's circuit breaker or fuse panel to ensure power is supplied to the heating and cooling system. Verify all wiring connections are secure.
- System Not Responding: Ensure the SYSTEM switch is set to either COOL or FURNACE, not OFF. Check that the fan setting is appropriate (ON or AUTO).
- Incorrect Temperature Reading: Ensure the thermostat is not exposed to direct sunlight or drafts, which can affect temperature accuracy.
- Fan Not Operating: Check the FAN switch setting. If set to AUTO, the fan will only run when the system is actively heating or cooling. If set to ON, the fan should run continuously.
- System Not Heating/Cooling: Confirm the temperature setting is appropriately above (for heating) or below (for cooling) the ambient room temperature.
