The Helios ACL is a smart electronic air quality sensor designed to control one or more ventilation fans based on the presence of oxidizable gases and unpleasant odors. Operating independently of general air quality metrics, the sensor activates ventilation only when necessary, enhancing energy efficiency and indoor comfort.
Equipped with an adjustable overrun timer ranging from 1 to 12 minutes, the ACL includes a startup delay of approximately 5 seconds for smooth operation. Its compact, surface-mountable housing is constructed from durable light grey polymer and is rated IP30 for protection against solid objects.
Operating at 230 V~, 50/60 Hz, and supporting up to 1A inductive current, the ACL offers a reliable solution for demand-based ventilation in residential and light commercial spaces. Ideal for improving air freshness while minimizing energy usage.
