the thermostat has an led inside the plastic housing that will light up when the system is put into the EM HEAT mode. but, that stupid little led produces some heat when in this mode and that little bit of heat inadvertainly raises the temperature of the thermostat 2 degrees above the actual room temperature; which also happens to be above whatever you had the thermostat set to call for heat;and your thermostat is now inadvertainly set too low for the room temperature that you want the thermostat to maintain !!! how can i eliminate that little led from coming on; wiring wise ????
