I have an issue connecting the Nest thermostat. Can you pls help me with the wiring?
That is my old wiring. The issue is W1/B/O (has 2 wires in one socket) and C (has 2 wires in one socket).
For reference - my old thermostat datasheet.
It has been a few days since the last reply, and I am going to lock the thread at this time. If you have any questions, please feel free to create a new post.
