    Hi there - this is the first time i’m posting so please be gentle with me. i’ve received a nest and need to wire it replacing my old Honeywell Thermostat T6360B. the wiring is not straightforward as the honeywell does not seem to have “C” and “N0” wires. i’ve attached sone pics of the current thermostat and wonder which of the wires go where in the Nest?
    thanks for your help

    OK
    AS I said turn power off as the Brown wire will probably be LIVE...!

    You’ll also need to keep your old heating programmer turned on for the stat to work
