Hi,
My combi boiler has a switch to isolate the power from it, but it has no fuse.
The boiler manual says there should be a 3a fuse protecting the supply.
I want to put in a wireless thermostat and I have it ready, but I am wary of wiring it in and damaging £100 of thermostat.
Is this normal to have no fuse in the switch?
Or would you advise swapping the switch for one with a 3a fuse installed before connecting in the thermostat?
