Optional Accessories
Auto Whirly
The Auto Whirly is an optional accessory and can be added to your Ventis at any time. The Auto
Whirly is designed to extract the hot air from your roof space on a hot summers day and draw
in the cool air from outside when the sun goes down to accelerate the cooling capabilities of the
Ventis at night.
When an Auto Whirly is fitted, it is activated and wired up to your controller by the Ventis Install team,
so there is nothing on the control panel that you need to worry about to get it operational. It is fully
automatic and will only operate when the roof cavity is too warm to provide any cooling benefit.
Your Auto Whirly is working when you see the
small fan icon on the right of the roof image.
You will see it in operation through the warm
summer months when it helps cool your home
by purging unwanted heat from your roofspace.
You will not see it operating at all through the
winter when we want to save the warm air
and provide that to help with your heating
requirements.
