For 6 years I have lived in a small house that had Hive heating installed. There was one control / schedule / boost for hot water, one for heating. Simple.
Now moved into a house that has Honeywell heating, just a wireless thermostat. I have no instructions left for me. On the thermostat it just has the temperature of the house e.g. 22c and then a small temperature above it e.g. 20c which I presume when it gets down to that the heating kicks in? How does the hot water for showers work then?
