I have an air-to-water heatpump that supplies me with hot water and also underfloor heating (UFH). The heatpump details are as follows:
Alpha Innotec 12 KW Air-to-water Heatpump,
230v / 1NPE / 50Hz
1NPE 230 VAC 50Hz
However, when the UFH system is set to "auto", the heatpump operates for up to an hour per day for no apparent reason - i.e. no room stat is calling for heat / it is not on a timer, etc. I have been taking detailed readings to confirm this and discovered that it is switching itself on up to 6 times per day for short periods at a time.
The company that installed the system has gone bust, so I can't go back to them.
Many thanks in advance for any thoughts on the matter.
