Dry contact output

Max. switch current: 6A (load resistance)

Four CO2 levels selectable to control the relay by jumpers

CO2≤700ppm the relay is on and CO2≥900ppm the relay is off

CO2≤900ppm the relay is on and CO2≥1100ppm the relay is off

CO2≤1100ppm the relay is on and CO2≥1300ppm the relay is off

CO2≤1300ppm the relay is on and CO2≥1500ppm the relay is off (default)
