Thermostat calls for heat and turns on fan simultaneously

[stevebergmann]

I just found this thread about the same issue and it seems like they are saying it’s the G wire like you mentioned. Maybe someone else will have more input, or ran into this and fixed it another way. Mine is all electric heat pump so I didn’t have the issue.

Wyze thermostat fan before heat

Is there a way to delay the fan until the furnace kicks on and flame has started? My old therm wouldn’t turn fan on until about 30 sec to a minute after it turned on so the furnace could heat up. The fan now just turns on first and blows cold air for about 30 sec or more before it heats up.
