My installer put the Honeywell TH8000 on the Infinity 80 air handler/furnace. My concern is that I cannot control the fan speed with the TH8000 unless I am missing something. Living in Phoenix it is nice during the heat of the day to have the fan on the high speed. Would I be better having the TH8000 replaced with the Infinity control? The system is doing a great job for this first summer except for not having that blast of air when the fan is only on the lower setting.
Any help would be appreciated...thanks
