Central heating is not working. In the last month or so I have moved some of the CH wiring, however I was meticulous about making sure it was reconnected exactly as before.
I'm actually suspicious of the Drayton Digistat 3 roomstat.
It has two connection wires. Is this just a normally open switch that closes when it calls for heat? Can I just connect these two wires together to check out that this is the problem?
Thanks, Roy
