HI! I am getting Trane HP XR16 2-ton, TAM7 2.5 ton, 2x5kw strips. 17 SEER). Thermo to have outside temp sensor. Thought of Prestige v.2, or VisionPro IAQ. Do not need internet, don't need HD screen, don't need apps, so unless some useful functionality, will get VisionPro. 1. Can Prestige or VisionPro save all its settings to a card/thumbdrive to reduce reprograming after power outage? 2. For heating/cooling staging, does either Prestige or VP consider outdoor temp sensor. 3. Is the Adaptive Intelligent Recovery on the Prestige such a money saver over the VisionPro AIR? Otherwise, sticking with VIsiionPro IAQ 1. Is it better for the VP to control staging on XR16 (instead of XR16)? Heat? Cool? Both? 2. For DEHUMIDification, is the Thermo best to control that through loweing fan speed? What happens to Condensor Staging when Dehumid is called for? I do not want "extra" cooling method. Is THIS something the IAQ is better for? THANKS for your help!

I have the 1st generation Nest that I am using with a hydronic in floor boiler system. I have a 2nd thermostat that contols a 2nd zone. I'd ike to control my Aprilaire 800 steam (with Aprilaire 850 Fan Pack) with one of the thermostats Does someone have a wiring diagram for connecting the 1st generation Nest, along and.or with the 2nd generation thermostat with AUX input? The humidifier is installed now with a stand alone Aprilaire thermostat (62) that has 4 wires to it (2 - 24VAC tapped the Model 800 the ) and 2 back to the humidifier connections in the model 800. It would be great to have a sensor that monitors outside temp to adjust the humidity levels - that may be a bridge to far! TIA
