Moved into a new house with Totaline thermostat/heat pump system. No literature that I can find. Have temp set for 75 on 2 thermostats in the house but won't heat above 70. What am I doing wrong or do I have a major problem with my system or could it just be the thermostat? This is a brand new multi-zone house... blower seems to work but air is blowing out cool. Have 2 zones totally turned off... hasn't made any difference. Any body got any bright ideas?
