Hi All, I have replaced one wall thermostat for a Nest to control Boiler, which works fine but, I have a thermostat controlling the UFH which is a John Guest Compact pump, is it possible to buy another Nest thermostat simply to control this pump without having to buy another heat link too? If not, how would I wire a new heat link to control the UHF zone? The current floor thermostat as far as I can measure closes a 230v circuit to power the pump on, my measurements of current on all heat link connections are not 230V. My UHF is simply one circuit in the kitchen dining area, the rest of the house is radiators which I am happy to adjust manually. I currently have the Nest in the dining room but want one in the lounge area where the radiators are. Any help would be greatly appreciated.
