A simple question. Can I replace my existing Honeywell T6360B wired thermostat with the Honeywell CM721 or 921 WiFi model.
The reason for doing this is to relocate with minimum disruption.
My existing stat has three wires. Will I only need to use two of them when I wire the receiver.
My boiler is a Potterton Kingfisher RS60 model
