Lennox G61V furnace and Lennox XC21 AC unit... Can two thermostats be installed to control these units (1 on 1st floor and 1 on second). There is no actual zoning in the ductwork.
AC is the main issue which will hopefully be less of an issue with this new equipment.
Example: If the 1st floor thermostat is set to 72 degrees and the floor is 72 degrees - there is no call for ac. But if the 2nd floor is 75 degrees can I have a 2nd thermostat on the 2nd floor set to 72 degrees that will call for ac again. I know the first floor might end up even cooler but thats ok.
Can this work? If so will the Honeywell IAQ thermostat work - it came highly recommended... if not what should I go with.
