Automatically switches the fan on when the quality of the ambient air deteriorates below an acceptable level due to fumes, odours, tobacco, smoke or dampness, etc.
Adjustable run-on-timer facility which enables the fan to operate for a pre-selected time period after the air quality sensor has switched off.
Important: this sensor must not be used to detect combustible gases or fires and in connection with any safety alarm systems.
