Could you tell me if this is wired correctly? We've tried the black wire in both sensor points, but it doesn't seem to be connecting to the underfloor heating. It's on a splitter thing so there's a different thermostat for the radiators in the rest of the house, and that is working but we can't get this one to turn the underfloor heating on. Have called a plumber but not sure when they'll be able to get round and we're cold!
It's a Danfoss TP5000si programmable thermostat.
Thank you!!
