Can anyone help. My Danfoss RMT24 as bust and I have been told to replce with a digital. I have a Honeywell T6620b. The main issue is that there are 3 wires from the danfoss in ports 4,1 and 3 but on 2 on the honeywell. The Danfoss has something called an RP on it but nothing mentioned in the instruction.
Can anyone advise if it is possible to install the honeywell and how to do so?
