I am replacing a miller non-programable thermostat with 5 wires. the 5th wire is blue and hot. I trying to use a Honeywell CT31a. I hooked up the wire as per location on old thermostat gr-red-yellow-white. The furnace works normally but the air and manual fan doesn't. I am not using the blue, should I?
