I have gas boiler powered central & water heating.
The controller is an EPH-TRFi panel & wireless thermostat.
Central heating is zone 1.
Water is zone 2.
Up to this week, if zone 1 was on & thermostat was at On temperature, the radiators would heat.
Now, even though zone 1 is ON & thermostat is On (i.e. room is below the requested the temperature), I can hear the boiler working but the radiators aren't heating.
If I then press zone 2 ON at same time, radiators instantly start to heat.
Any ideas? I tried changing batteries in thermostat but that was likely a red herring.
