    Fan won't turn off regardless of setting
    Hi all

    My system uses a gas furnace and an electric air conditioner.

    I have decided to install my Noma 5 + 2 Programmable Thermostat model 52-2557-0 from Candian Tire. There are 4 terminals on the back
    G R Y W

    My old thermostat was a Honeywell FocusPro TH5000 Series

    I have a Red Wire, Black Wire, Green Wire and a Blue Wire (which is my White I believe) These were all hooked up to the honeywell in the following manner:
    Rc Red wire. R Black wire These were jumpered together.
    W had the blue wire
    G had the Green wire

    I have installed my new Noma like this:

    Both the Red and Black wires going to R
    I have BLue going to W
    I have Green going to G

    There was also a brown and an orange wire that were not being used by the old thermostat. I did not connect these

    The heat works correctly. I did not test the A/C since it is winter.

    My problem is I can't get the fan to turn off. It runs constantly regardless of if it is set in Auto or ON in the controls.

    Thanks for your time;
    Logan
