Hi guys
Im trying to connect my old room thermostat from previous boiler to my new boiler Biasi Riva Plus HE28 (M296.28SM/C) Im a bit confused coz in room thermostat are 4 wires (like on picture)
and manual says how to conect 2 wires
Should i remove that black loop and connect it like this
If yes what about the rest of wires???
