I believe so, my system is baseboard so I didn’t use a fan. There is a fan control option on the device. The instructions say it can do auto, on, of, circ.

I’ve got a couple Honeywell T6 z-wave thermostats that work great and didn’t cost a lot. I control them through home assistant with some custom code to set them on a schedule, but they can also still be operated manually if needed.
I’d highly recommend not doing that. A smart thermostat is much easier and going to be a lot more reliable. And it won’t stop working if your server goes down.
Is it? I guess I don’t know the difference… I installed mine myself but my system is also dead simple - only 2 wires. My first thermostat was just a bi-metallic strip. 😀
