Hi all, hoping someone can assist me connecting the correct wires from my 3 core and earth flex from old Honeywell thermostat to new DT90E, a photo is attached. In the wiring unit connector block, red goes to white (control head 3 port), black to black (boiler or controller) blue to most blues. Hope this makes sense? Thanks in advance
