Designed for the Classic DVS Ventilation System, Automatic Summer Ventilation delivers a continuous supply of fresh, filtered air,
drawn from outside the roof space, when the roof space itself becomes too hot.
This allows you to ventilate your home with fresh air throughout the summer
months - without the need to leave windows or doors open. DVS
Automatic Summer Ventilation allows you to reduce pollen, dust, insects and noise, and
improve your home's security while enabling you to enjoy a constant supply of fresh, cooler air, day and night.
Automatic Summer Ventilation, which can only be fitted to the G3
model from the Classic DVS range, regulates the incoming air depending
on the temperature of the outside air and the roof space air, according
to your comfort settings on the G3 control panel.
