Hi. I have very old underfloor heating with thermostats. I'd like to replace the thermostats with timer/thermostats if possible. The current (very old) ones have 2 red cables, 2 black and an earth. One of the red cables is live all the time, the other live when the thermostat kicks in. It appears to be mains voltage. Can anyone suggest a replacement thermosat with a built-in timer please? Many thanks.
