You probably have a wire crossed or your heat mode is being powered all the time. Check to make sure the thermostat and wire to the furnace's circuit board are wired right. G = green wire, W = white wire, R = red wire, C = blue, brown or black. Check to make sure both the thermostat wires correspond to the furnace. If that doesn't work your thermostat might be bad and not detecting the temp inside the house properly.
