I have a new Evolution system in place with three zones. One of the zones is not holding the set temperature properly. It will say it is 62 when the set point is 68.
When I have looked in the advanced diagnostics area, I see under "LAST TEN SYSTEM EVENTS" the entry "ZONE2 AIRFLOW LIMITED SHUTDOWN OCCURRED" and it says like 117 times!
I'm just guessing here, but does this mean that there are not enough vents or the vents that are there are too small? They are coming out to take a look, but as usual the more education I can have in advance the better.
I have noticed that you can turn down the max airflow to a particular zone. I would think this isn't what you really want to fix the problem?
