Hi folks,

We have just moved into a new house and found this suspended in the loft.
It has a big 9" vent into the landing ceiling and blows air?
I can find where is tied into the mains so wondered if it is automated? If it is regulated or just runs constantly?

Thanks

James

Looks like PIV (random google result here

Stops condensation and mold by blowing fresh air into house forcing air out.
