Hi, I have contacted the manufacturer and they say.....
Thank you for your enquiry. Are you referring to the Thermotouch 3.2aP? At present it does not have the functionality that you describe.
Not sure why as an under-floor heater and a wall heater same sort of thing. Have you actually used this system for electric wall heaters?
I don't mind each wall heater having its own thermostat which I presume is what the 3.2aP offers but I am not worried if it was simply a 'switch' as each heater has its own thermostat. I actually only need a simple on / off function. Any ideas?
