INDEL WEBASTO MARINE ISOTHERM Smart Energy Control

By means of a sophisticated micro-processor, this device drastically reduces the energy consumption of fridges and refrigerating units. It continuously adjusts the compressor RPM and, by means of a special sensor, it detects the refrigerator air temperature thus cooling food a bit more than necessary when the boat engine is on or when the boat is connected to the dock. During navigation, it exploits the food surplus frigories to reduce the compressor operation with an energy saving of about 50%. This device can match any fridge or refrigerating unit fitted with SECOP 101N0212 electronic unit. The kit includes: panel with micro-processor, adjustable potentiometer, air sensor.

It doesn't match the CR42 fridge version.
