Background: I'm building a new, one story house in Central Florida. Furnace is Lennox G60V with two stage heat and variable speed blower. A/C compressor is Lennox XC21 with two stage compressor. Home has four HVAC zones.
Dealer proposes to control the Lennox equipment with Honeywell TZ4 zone controller and Honeywell TH8320U1008 main T'stat with 3 TH5110D1006DAG T'stats for other zones. There will be Honeywell dampers, including bypass.
My question: Will the Honeywell TZ4 properly control the system, including making full use of the variable speed motor? I had been expecting a full Lennox system including Harmony III zone controller and SignatureStat T'stat to control the system and lower humidity.
Are there advantages to the Honeywell controls over Lennox that I am missing?
