Question about Honeywell Programmable Thermostat Heater
If you have a forced air furnace with an air conditioner attached make sure you have a jumper wire between Rh and Rc. If the Bryant thermostat had a wire hooked up to C you do not want to hook this up to Rc. Just cap it off and put it back in the wall or disconnect that wire down in the furnace.

Some programmable thermostats require a comon wire to the transformer side of the 24V transformer. Check and see if this is true. And then look and see if your old thermostat had a "c"terminal used. Also would help if I knew the terminal designations your original thermostat had and the new one has.
If this helped you please rate me accordingly as high as you can and if you need more information please post back.
