Manual dampers vs. motorized w/smart sensors and zone control...
Replacing old furnace and a/c for 2500 sq ft single level home. Existing set-up has a Honeywell 3 zone control panel in place, with 2 zones hooked up, but discovered that only 3 out of 7 supply take offs have any dampers at all. One option is to have the installer just cut in manual dampers to help balance air flow and redo the plenums for better distribution. For reasons unclear to me, he’ll remove the control panel in this case. (Can anybody tell me why that would be necessary/adviseable?)
The other option is to pay up to have a new zone control system installed (Carrier's Infinity) with control board, 2 motorized dampers and one smart sensor inside and one outside. I haven’t been able to get any clear idea of what the motorized dampers and smart sensors will do (other than break more often…). When I ask the answer is “greater comfort” and “the system will be able to adjust to your room-to-room needs” How? It’s not like there’ll be more than the current 2 thermostats (which are also called Infinity Control systems). Can anybody explain how these high end “smart systems” work and whether it's really any better than balancing manual dampers with 2 thermostats..
