    Noma Thermostat manuals THM403
    We bought a new house and purchased a Noma 403 programmable thermostat and had the heating company install it in our house, but he never left us the manual and as a result we have no idea how to program it. Is there someone out there who can tell us where to go to down load a manual. I've tried typing in Noma and all I get is a catalogue from Ireland showing what lights to purchase. Thanks for all your help.

    The model number you posted is not listed by the manufacturer which is UPM Inc.

    Look around at this site for your model number

    Thank you hvac1000 for your reply. I have been on that site, looking for a manual, and I did not find our thermostat model there also. So that is the reason for my question... the model number is written right on the thermostat "Model Noma 403". So I know that they did manufacture the one that I have. I just can't find a Manual to tell me how to program it. So we'll just have to continue playing with it, and hopefully we'll stumble on the correct way to programme it.
