Continuous fan

SRTobias — Tue, 07 Mar 2023 16:56:35 GMT

By building code requirements I need to run the fan continuously during occupied periods. Most thermostats have a (auto or on) setting and can be set to run continuously when the heat or cool is scheduled on. I only need to run the fan on the days and hours the schedule is on. I need to use a different thermostat if Nest can't do this.

You can run your system's fan independently of heating or cooling. So your system doesn't need to be actively heating or cooling to run the fan.
However, you can only run the fan when your thermostat is set to a temperature mode (like Cool mode, for example). You cannot run the fan if your thermostat is set to Off.
You can set the fan to run a fixed schedule or manually set it to run. It can't be set to automatically run or switch off when you leave or come home.
You'll see a fan icon on the temperature screen when your fan is running because of your fan schedule, or if you've turned your fan on manually.

I hope this helps you understand the fan control of your Nest Thermostat

As I understand the Nest fan operation is not the same as most thermostats. Most thermostats have a on or continuous setting. Most thermostats enable the fan to run with the heating and cooling schedules. Nest thermostats use a separate fan schedule that doesn't apply to the normal schedule. This results in the fan running when it is not needed. I hope you can understand this.
