Good insulation reduces fan effectiveness.
Are attic fans with humidistat effective.
Unlike a ventilation fan a whole house fan an attic mounted fan that exhausts air from a home at night is designed to cool a house that is to lower the indoor temperature.
If it is below the air it draws past it will satisfy the control too quick shut off then kick on again etc.
Make sure you mount the thermostat humidistat above the fan as far as possible.
Only installation required is the electrical hardwiring.
The normal indoor humidity range in winter should be 15.
The downside of attic ventilation fans.
Attic fan with humidistat.

I like to put a pigtail on mine then plug into a receptacle so the next guy can replace it easier.
However the utility of attic ventilation fans is actually quite a controversial topic.
Attic ventilation fans whether hard wired or powered by their own solar panels seem like a low cost and effective way to help keep your house cool.
The fan comes fully assembled out of the box.
