How and when does the wyze thermostat trigger the ventilator on the * wire? I have a simple, normally closed 24vac damper on a duct to outside. A spring closes the damper when it is de-energized. I used to hear the damper open periodically with my Honeywell system - that could be programmed following ASHRAE standards.
During set up it asks if I want to use the ventilator to help cool the house. When else will Wyze energize that circuit?
It would be nice to have manual control over this too.
