Why does the circulating air motor keep running when the Truma Combi heater is switched off?
This function protects the Combi heater from possible overheating caused by heat build-up. The circulating air motor gives off the possible heat build-up into the vehicle interior during the after-run period. The after-run is activated every time the system is switched off, even if the Truma Combi heater was only switched on for a short time. You cannot deactivate the fan after-run.
