How it precisely work. Imperial xdh 7.15

Hello
I've seen the product imperial xdh 7.15 ,
It has 5 hole , it doesnt use the same air waste to redistribute into the home. It take from a specified room.

My question is when in recirculation mode,
While it is recirculating, does the waste air from bathroom still going outside?
or inverse when using bathroom button does it make the air outside going inside or does it take inside air since it is in recirculation?

Can someone who own it or is good in ventilation clear me out on this? Thank you

Max

Welcome to the forums.

You should put Canada in your location in your bio.

That unit isn't designed to be used on a bathroom exhaust fan.
It uses two lines into the house. If your bathroom is set up with two lines then the recirculate mode brings in a constant stream of fresh air and discharges a constant stream out of the bathroom.

This is the link for the product. On the right side are all PDF files describing the operation.

Thanks for your reply max,

If i understood correctly, in recirculating mode, it takes fresh air from the auxillary line.

but in the brochure it shows that the primary exhaust air nothing is happening , is that so?

​​​​​​Does it have to be in continious circulation for that air going out of the house?

I think it switches to continious mode for 20 minutes when a ventilation is requested and take air from outside in that time and come back on recirculation mode after .

that's good for me then 🙂
