    Honeywell RTH7400 program schedule override
    I am unable to make a temporary adjustment to the temperature setting by pushing the up or down arrow.
    Is this because I connected the wires incorrectly?
    I only had two wires from the old Honeywell T87f28373 - one at 6 O'clock and the other at 8 O'clock.
