I need the expertise of a Professional re. ClimateMaster. Can a ClimateMaster 27 run with both the 1& 2 stage heating and the Aux heating element running simultaneously? Put another way if a call to the thermostat W terminal is made are the Y1 & Y2 terminals cut off? This query follows the installation of my Ecobee3. As soon as a call is made to the W terminal power is cutoff to Y1 & Y2 since I have the power to my Aux heat element turned off the unit simply recirculates the room air and my room temperature drops. Thanks.
