Default Need control

I've been running this 80W blower from 8AM to 8PM ($4.94/month) and the basement temperature is slowly climbing.

I don't want it to get too warm in the basement, so I'll have to add controls soon.
Monitor the inside temperature and try to limit blower operation to under 72F.
At the same time, stop the blower, if the outdoor humidity is too high.

Winter Operations:
In the winter, when the basement normally gets down to around 55F to 45F,
Maybe I can run the blower in cooling mode.?.

I would set Cooling Mode, only when the outdoor air is colder than Basement air.

Set the blower to come on and run, until the basement air temp is <=44F. *
After the blower stopped, the slab/geo heat and leakage from the rooms above,
would slowly heat the basement back up to above 44F, restarting the blower.

*Note: 44F is just an example. I would use the average basement air temp overnight as the setpoint,
and use that setpoint -2 deg F as the low limit.
