Has anyone used this new zoning setup from honeywell....
It's an Envirazone board with VisionPro IAQ Stats.
I was going to have 3 zones installed using a TZ4 board along with VisionPro Stats to control a New Rheem MOD as a 3 stage setup, but the last contractor to bid the system suggested this new setup.
The TZ4 board has a lot of flexibility as to how the stages can be controled (stat-time-% of zones calling), but I don't see all those options on the Envirazone board. The Envirazone literature I've read talks about the stats controlling the staging, along with P+I. I asked the HVAC Contractor and he "thinks" the new system is at least as flexible as the TZ4, but didn't sound 100% convincing. It looks to me like the stats control, and when the "system" senses a stage has reached 90% capacity it bumps up to the next stage. Is this correct?
This system seem like the cats ass, but will it do as good a job on controlling zoning along with staging as the TZ4 board, or does it do a better job.
