There’s no pattern that I can tell.

I'm not familiar with the specific hardware, but my guess is NMT has it. THere are HVAC controls that will tell a system to "move the air around a little bit every once in a while" which is especially useful when there's an upstairs and downstairs (hot air rises). My experience is what NMT says, you can set some systems to circulate the air X% of the time. What that usually means is "even if the HVAC hasn't run, every hour or every 30 mins or every X-time, kick the fan on for . In our old place, that was super useful in the time of year (spring and fall) when we didn't need the AC but without the fan, the upstairs/downstairs temps could end up 5-10º different.
