Question about Heating & Cooling
I have a Carrier Comfort Zone II with 2 controlled zones. The floor with just the sensor controls perfectly. I set that zone at 75 and it stays at 75. The other zone has the actual thermostat. If I set that temperature at 75, it cools to 68 before the unit shuts down. If I raise the set point all the way up to 90, the temperature holds at 73. Do I have a bad thermostat or is there another solution?
Sounds to me like a bad damper or a bad zone panel. Turn tstat off and call for cooling on zone 2. Then see if your still getting cool air to zone 1.( where the main tstat is)

sounds like your zone control tstat needs calabrated or maybe replaced,in owners manual there should be a section on calibration if not you may have to replace it

The stat that works is called the main and the other two are called slave stats. The stats must be set to heat or cool the same as the main. If you want one room to cool and one to heat , sorry. Need to upgrade to auto changeover. Is this AC actally a Heat pump?
