I had a Rheem 18 SEER 2 Stage AC installed this week. The dealer did not install the Rheem 500 Series Thermostat. I'm just trying to understand why they did not install the Rheem 500. I would like the additional humidity controls the 500 series thermostat provides. However, before I complain I would like to be a little better educated on the subject.
Is it difficult to install the 500 Series Thermostat? My AHU is in an upstairs closet and the thermostat is on the wall just outside the AHU. Do they need to run a wire from the outside unit to the thermostat which could be difficult?
Overall, I am happy with the unit and cannot believe how quite it is when only Stage 1 is running which is most of the time.
