After doing some research the current T stat I have has built in cycle (built into the software) that kicks on the fan every 20 minutes to run 10 minutes even if the furnace has not called for heat. Looks like other people have experienced the same issue.
There are three settings for Fan : ON, AUTO, or PROGRAM
This is a feature built in: a unique circulator fan cycling mode which automatically cycles the fan on for 10 minutes and off for 20 when the thermostat has not called for cooling within the past 60 minutes.
My home temperature does not drop below my set temp, but the fan still clicks on every 20 minutes. It is really annoying.
Looking for suggestions into a different T stat to not have the same issues.
