    Looking for new 3 wire thermostat
    So far I've been out of luck finding a replacement for this thermostat. The one shown was made by Durodyne, they have no suggestions for me so...

    Does anyone know what would be a replacement thremostat for this? I have no clue what the numbers and letter on the wiring refer to (4, 5, and C). Any help would be much appreciated. I live in an isolated town so can't really call anyone here to have a look.

    Here are pics of the thermostat:





    Thanks for the help.

    Is this in a mobile home? I bet it is. The reason I say that is some mobile home systems use a 3 wire system.

    No this is in a stick built R2000 home. Our furnace has a two speed motor.

    You might take a look at this

    DuroZone Thermostats

    Also where they are made

    Duro Dyne Canada Inc Home Page

    The thermostat is for a zone system. I wish you would have said that in your first post.
