Among numerous new releases for detecting humidity and air quality, Swidget has introduced the 20/40/60 Control Switch. Installed using existing wiring, the switch works with the ventilation system to boost indoor air circulation when it’s needed most. A single pole, dry contact, isolated switch with a built-in 20-40-60 automatic shut off timer and LED indicators can boost anHRV (Heat Recovery Ventilator) or ERV (Energy Recovery Ventilator) when needed.
Snap in one of the sensor inserts and automatically engage the timer switch based on environmental conditions. Even better, pair the Control Switch with a Swidget Temperature-Humidity Sensor Insert to control the ventilation fan in the bathroom when humidity levels rise.
