    Hello,

    I know very similar questions have been asked but they haven’t covered this version of Slaus from what I have seen. I apologise if it has.

    I have a Valliant ecoTEC pro28 boiler which I believe has a Salus VBC600RX wireless thermostat. The boiler is a combi boiler which delivers hot water on demand. The wireless thermostat receiver actually plugs into an interface on the boiler which is easily removed and I have ordered a blanking plate to replace this.

    I would like to install the Nest thermostat E. I believe I know how the wiring should be but I would like to double check as there isn’t anything there at the moment.

    Pictures attached to show full set up and wiring.

    Any help is appreciated.

    Managed to figure this out myself. Just had to remove the loop in the 24V RT and add in new flex wires. They then connected into C and NO on the NEST. It didn’t seem to matter where the wires went but I used the brown wire for C and the blue for NO.
