I installed the 3m-30 yesterday and the display has "AUX HEAT PUMP" on it. I am assuming this means my electric bill is skyrocketing. I checked the wiring (5 wire heat pump w/ aux heat) and checked my settings, Type HP and Source ELECTRIC. I tried option A and b on the HVAC SET UP screen. The heat works and runs by what I have programmed, but I can not figure out how to get the AUX HEAT PUMP to just be HEAT PUMP. I have swapped around the DIFF and SWING settings with no change. When I go into TEMPORARY menu and change the temperature, then select HOME, the words HEAT PUMP flashes but not AUX. When I toggle the EMER/OFF switch to EMER, the display just says AUX, in OFF it says AUX HEAT PUMP. So question is am I running 24x7 in AUX HEAT PUMP with high power bill or am I running 24x7 efficiently w/ HEAT PUMP only? I've called the tech support number several times, and each time i am asked to leave a message. No one has called me yet! Thanks.
