I am getting a York Pt9 80,000 btuh furnace installed in my house next week (2stage, multi-speed (not variable)). The installer says he will put in a Robert Shaw 9600 programmable digital thermostat. When I went to check it out online I saw the following: "System configurations:
2 - 5 wire single stage gas, oil, or electric systems"
Does that mean this is intended for a single stage system, not a 2 stage? I look at the other model #'s like say the 9615 and they say the following: "System configurations:
Multi-stage gas, oil or electric heating/ cooling syatems (up to two stage heat, two stage cool)"
Need advice - will this properly operate my 2 stage furnace?
