The durable, high-performance, Grozone OSW – On / Off 120V Switcher uses a low-current sense cord with lower and upper receptacles in one module to increase flexibility. Some of its functions include:
- Stop the exhaust fan of a CO2 controller in order to eject CO2.
- Turn off the humidifier or fogger of a fan control when the fans are on.
- Shut down re-circulation fans of an air conditioning unit when cooling.
