Replacement Room Thermostat
I have just bought a Drayton Digistat RF3 wireless programmable room thermostat. Problem is when I tried to wire it into the boiler I got stuck and was unsure about how exactly to do it!
I figure the thermostat just wires in to replace the existing boiler only thermostat. The problem is that the four wires going into this unit were only labled P1, P2, A1, A2. I have no idea which ones are live and neutral and which ones control the switch.
Can anyone help please. I would really appreciate it.
Thanks very much.
