Replacing Basic Dial Room Thermostat with Digital programmable version

What happens if you crank it upto 25 c or more ?
Does the house then get hot ?

If it's a digital two wired one like you say then it must be battery powered right?
For it to work you should have a live and a return live (to the boiler) wired to it.

Hi all, thread is old but I thought I would try my luck....


I have replaced my old dial 3 wire thermostat with a digital two wired one. (Just a generic brand)


I have wired up the live and the earth and left the Neutral wire disconnected.


I have clearly done something wrong though as now radiators only get warm to the touch rather than 'proper hot' and the house does not very often reach the desired temperature.


I have a standard boiler with radiators and a hot water tank.


Can you give me any advice or do I need to get a professional in to do the job.

So did you assume that the black/blue wire was the neutral then?

You need to post the make & model of both old and new stats to progress with this.
