Hi,
Tearing my hair out here over something probably very simple! I currently have a Worcester Bosch 28cdi combi boiler which has no remote thermostat. I therefore purchased the Honeywell CM927/921 wireless thermostat. Has anyone had any experience of fitting this?
Do I just remove the current control unit and wire in the Receiver box? The current control unit only has three wires connected to it from the boiler but the Honeywell receiver says it requires 4? I'm a bit of a biff when it comes to electrics but thought this would be fairly simple!
Any advice, greatly appreciated!
