    I need some help with a 240V baseboard heater problem... I bought two smart thermostats for my home. I installed the first one and it powered on as soon as I flipped the breaker back on. Turned the breaker back off, and installed the second one. Flipped the breaker on and it worked too - yay...

    Do AC powered wireless thermostats exist

    Hi, Does anyone know of a wireless thermostat which can be mains powered rather than batteries? We have very difficult cable routes for the control cables but easy AC supply. It seems a shame to hang the system on batteries if the stats could be main supplied. Thanks in advance.

    Underfloor heating thermostats

    I tend to run a mile from underfloor heating as its a pain in the backside to put right if it goes wrong. Got a regular customer whose old manual thermostat has died, power goes to it, but nothing else, its dead. Tested resistance of the heat mat and the values pretty much same as paperwork when...
