I'd appreciate assistance with the following issue.
I have a 3800 SF home in Wisconsin currently with a single stage Carrier furnace and 3 zones controlled by a Carrier ComfortZone II system with Carrier dampers, all installed in 2004. I'd like to take advantage of current incentives and install a fully modulating furnace and have 3 quotes for installations for a Carrier, Lennox and Coleman system. I am not planning to replace my single stage AC at this time.
My issue is that I am not inclined to use the proprietary communicating thermostats offered by the manufacturers and would rather install a Honeywell zone system with Prestige controllers. I can get into why I'd rather use Honeywell but I don't think it's essential to my question. Everything I have found so far states that the Honeywell system will not communicate fully with the various furnaces and enable them to fully modulate. However, my Coleman contractor says that if I install the Coleman CP9C furnace and a full Honeywell control system (replacing the zoning board with Honeywell HZ432K) that I will get full control of the modulating furnace and will lose no ability compared to the Coleman Echelon Thermostat.
I am looking for validation that this is true, and wondering if there are other furnaces besides the above that I should be considering.
