    Noma programmable thermostat
    I am replacing old thermo with Noma programmable one 52-2546-6. My old thermo has only white and black wire. Where they should go on Noma. Instruction say: common goes to Rh and the other to W. Is common always white wire? So white goes to Rh and black to W? They also have jumper between H1 and H2. Do I have to remove it ?

    Yes, one wire to Rh and one wire to W. If you only got 2 wires, black and white doesn't matter.
