Best option for whole house attic fan

[MarkTr]

Lots of conversations about this if you use the search function. Here’s a recent one:

Whole house fan control

I had the same situation with my fan. There was a hi/lo switch and the on/off with timer. What I did was remove the on/off with timer module and replace it with a GE in wall on/off paddle switch. I left the hi/lo in place because I didn’t feel that there was enough need to figure that one out. lol. I use automation with my fan and it works great. Basically I have rules that when it turns on it checks to make sure there are XX number of windows open. If there aren’t enough windows open it turns off and alerts me about the windows. It also turns off the thermostats when it turns on. When it turns off it announces what windows are open, this way I do not have to check every window in the house. It also turns the thermostats back on and sets them for the appropriate mode. It would be nice…
