Honeywell IAQ Firmware Levels
My dealer has offered to include a Honeywell VisionPRO IAQ YTH9421C1002 in my system (new Tempstar 95% eff VS furnace, existing Carrier A/C) instead of the Vision Pro 8000. I have seen several references to that model ending in 1002, 1004, 1010. I believe these are the different firmware levels. (?)
1) Where could I find the specs on the changes in these firmware levels?
2) Should I be concerned that my unit has older firmware?
3) How would I go about downloading new firmware into the thermostat, assuming that is possible?
