I recently installed the (much cheaper German supplied) cooling resister in my Arotherm Plus and my tech configured the cooling parameters with apparent success because when set to manual and turning on “Cooling for several days” my Sensocomfort display confirms that the system is indeed in cooling mode. However it appears not to be working because, checking the master controller live monitor, it says the heat pump is in Standby mode most of the time with no cooling capacity, except when the DHW heating is needed, when the pump comes on and the cooling capacity starts registering. I can’t find anyway of getting the pump to kick in with just manual cooling/cooling for a number of days turned on. Is there some other trigger needed to force the pump to kick in for cooling only on?
