    Wiring to a new noma thermostat
    I am trying to install a new Noma programmable thermostat.
    My problem is that the existing wires leading to the thermostat are, Red, White, White, Red.
    Does anyone know how this should be wired?
    I've tried a lot of different combinations, and nothing works at all?
    Thanks

    You have a non code wire color wiring going to your thermostat. You will have to sound out each wire and find where it goes.
