replacing analog with digital room thermostat

[Scot Maclachlan]

It's part of a Polyplumb wet underfloor system. https://wattswater.eu/catalog/regul.../room-thermostat-wfht-dual-with-floor-sensor/

From the diagram below I would assume 2 is live in and 1 is live out. On that basis, for the DT90E, would 2 be connected to A and 1 be connected to B, with all other wires capped off?

I don't need the timer connected as I only want it to be a thermostatic switch.

My existing stat looks like this. Can anyone tell me how I should replace it with a DT90E1012?

Simple you don't, the thermostat you have is for under floor heating, so it switched both line and neutral, and it also has a sensor in the floor to stop the floor getting too hot, any replacement must use a CTN 10K sensor so the DT90E1012 is simply not suitable. Also you should also start your own thread not Hi-Jack a year old thread as any answers are not to both questions.

Not strictly correct, as the floor sensor is not fitted it acts purely as a room thermostat, so the question is the same. By the way, hijack is one word.

You’ll not get any help if you do that sort of thing round here, just saying.
