I have a visionPro also. whats is best to set to? Should my fan be on all day or CIRC?
depends on your area. in my very humid summer running a fan in the "on" or "circ" positions can cause major moisture issues, which leads to substance isues i strongly recommend to everyone to just leave the indoor fan in the auto position
If you have variable speed blower, I would run it ON all the time, but if you have standard blower, then Circ. You can do ON all the time. but can be drafty for some people. In the summer.. only run Auto.
