Need to replace a Honeywell PC8900 tstat with W8900 remote module. Trying to control 2 stage warm air furnace, powered humidifier and outdoor sensor. Existing Trol a Temp TTZ3 works ok. Also, there are 2 zone dampers. I'm considering a VisionPro IAQ YTH94211002. Are there any wiring problems to consider or is it and easy swap out?
