Vokera Compact 24 boiler - mechanical timer replace to wireless thermostat Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

[Panayana]

Hi, I have a Vokera Compact 24 boiler with mechanical timer. I want to replace the timer with an RF wireless thermostat (Salus RT510TX).
Please help me about the wiring. Wires coming out from the boiler: Brown and blue is clear but what about with red and black? Are they going to what port of the Salus terminal? Salus needs L, N, COM and NO. Which is which? Thanks
