https://www.googlenestcommunity.com/t5/Nest-Thermostats/Running-whole-house-fan-all-day-and-night-but-not-the-evening/m-p/134635#M28865 <P>I see how to configure the whole-house fan to run for any contiguous period each day, as long as that period doesn't span midnight. Electricity is most expensive for me from 5PM-9PM, so I'd like to run the fan all the time except during those four hours each day. I tried setting the start time to 9PM and the end time to 5PM via the Nest webpage, but that results in the fan running all the time. That seems like a bug.</P> Sun, 03 Apr 2022 15:34:36 GMT rocksnhills 2022-04-03T15:34:36Z https://www.googlenestcommunity.com/t5/Nest-Thermostats/Running-whole-house-fan-all-day-and-night-but-not-the-evening/m-p/134635#M28865 <P>I see how to configure the whole-house fan to run for any contiguous period each day, as long as that period doesn't span midnight.
