Fan turns on briefly

joshmerdjoshmerd Charleston, SCMember

I just installed my ecobee and I have an interesting issue. It will run fine until the desired temperature, cut off like it's supposed to, but immediately the fan turns on for about 10 seconds then goes off. I don't think it is short cycling per se, and I have the minimum fan running time set to 5 minutes.

Any ideas why the fan comes on for a few seconds at the end of every cycle?
