Fan not working with heater

Had to reset thermostat do loosing WiFi and now the fan with heat doesn’t work, but the fan works with the ac. Had to reinstall/add Wyze thermostat to app and there’s also no fan option?? What now? All wires are still the same and everything was working just fine before. Anyone have this issue?

what do you have in settings>advanced>fan activation delay ?


This is all I see…

when you reset your wyze, did you remember if you had a C-adapter in your furnace? if you do, you need to tell the wyze that you do not have a C wire, and instead you have a G wire during setup, so that it will know that it needs to send the fan signal differently to the C adapter.
