Adapter suitable for Truma and Alde temperature sensors - more precise room temperature for Truma Combi & CP Plus spacer

Many owners of a Truma Combi heater are familiar with the problem: The temperature set on the CP Plus control panel often does not match the actual room temperature in the camper. The reason often lies in the position of the standard temperature sensor.

The original sensor is usually deeply embedded in the wall and therefore partly measures the wall temperature instead of the actual room air. This can lead to incorrect readings and unpleasant temperature fluctuations.

This specially developed adapter for the Truma temperature sensor provides a solution.

✅ The Solution

The adapter positions the temperature sensor further into the interior and, thanks to integrated air vents, allows actual room air to reach behind the sensor.

👉 Result:

more realistic temperature measurement
more stable heating control
more comfortable climate in the RV

🔧 Principle of Operation

The sensor is slightly extended from the wall
Distance to the cold or warm wall is reduced
Air openings ensure better air circulation around the sensor
Measurement takes place closer to the actual room temperature
The idea is based on a frequently used practical solution in the camper sector – but here cleanly implemented as a precisely fitting component.

✅ Advantages at a glance

More accurate temperature measurement of the Truma heater
Optimized heating control
Easy installation without modifications
No changes to the electrics necessary
