Hi,This afternoon out of the blue our 3rd Gen thermostat throws up a H72
error. No power outage, no Wi-Fi issues, no work being done, all fuses
fine (none tripped). Any suggestions on how to fix this please? Many
thanks
Hi JonathanThe heatlink is displaying no lights - power is going to it,
confirmed by a contractor, but it isn't working. Thermostat is wall
mounted and was working perfectly fine until Sunday afternoon. No
trouble shooting works as the heatlink isn't...
