Scheduling furnace fan only

I am looking for a way to schedule running the fan only for an hour or 2 every day. Does anyone have any idea on how I can do this? My thermostat only lets me set times and temperatures....

Honeywell pro 8000 can do this.

That is an expensive thermostat - anyone know of a cheaper model that can handle this as well?

Get a 24 hour time clock with dry contacts and wire the contacts between the R and G terminals on the thermostat connection board of the furnace. Program the time clock as needed.

Note, if you have a variable speed blower this will run the blower at the slowest speed. If you have a conventional blower this will run the blower at the cooling speed.

Why do you want to run the blower?
