co2 switch CSC-1

CO2 switch CSC-1: 4 switch outputs for direct control of industrial fans

CO2 ventilation controller for maximum human and facility safety

CSC-1 is designed for the control of supply and exhaust air ventilation devices, based on the measured CO2 concentration.

A two-stage adjustable switching threshold is integrated into the device for automated ventilation function. The CSC-1 also has a direct 230V power supply and two switching contacts for fans, each with a maximum of 230VAC / 500W and two potential-free contacts. Thus motorized vent flaps in exhaust air ducts alongside electric window openers can be controlled.
