Good evening I currently have a Danfoss TPone-m thermostat upstairs and downstairs linked to my Potterton combi. I have purchased the TPone-s which has wifi, allowing me to remotely set my C/H. This comes with a relay. Can I used my existing relay and simply change the thermostat controller on the wall and set up to my wifi?

Thank you.

The M version is a mains voltage programmable stat. These normally controls the CH/HW and boiler via one (Y Plan), two (S Plan) or three (S Plan+) motorized valves What existing relay are you talking about?
Well I am not quite sure what it already has but there are two boxes wired in marked upstairs and downstairs but these have no lights or buttons on them and sit just inside the boiler cupboard
They could be motorized valves but could you post a pic of the two boxes, just to make sure?

It would appear it's a danfoss wiring centre on the right and two electronically activated valves so my question would be, where would I wire the DBR RF relay.
