Honeywell.com site. There, I find that my quote has a "Vision PRO" control (still not sure which one); and Dash is recommending (I think) "Vision PRO IAQ" (not sure which one of those, either).
As shown on the Honeywell site, there is a list price difference of about $200 between the low end of the "Vision PRO" line and the high end of the "Vision PRO IAQ" line.
So, I need to get smarter about which control is quoted versus which control has the features I need. Any helpful suggestions from you guys are welcome, as always!
