Hi
Can anyone help? I want to replace an old British Gas RS2 thermostat with a digital Honeywell DT90E. Not sure about the wiring, I have 4 wires in the RS2, one of them bare and disconnected. Images below show the RS2 and diagram of the DT90E. Where should the wires go? Boiler is an Ideal Combi +.
Thanks
