CO2 SET POINT CONTROLLER
The SPC-1 is designed to easily monitor and control CO2 enrichment. Just set it and forget it. This appliance is recommended for indoor use only.

HOW THE SPC-1 WORKS

The SPC-1 samples the air and determines the concentration of CO2 in PPM. Then when indicated by your set point values (desired PPM CO2 and elevation), the unit will activate CO2 enrichment equipment plugged into the piggy back cord. The SPC-1 has a fixed hysteresis (differential) of 20 PPM.

EXAMPLE With a CO2 set point of 1000 PPM, the unit will activate (turn "ON") whenever concentrations fall below 1000 PPM and continued to control and allow your CO2 equipment to enrich your environment until it detects about 1020 PPM. The SPC-1 is a reactive CO2 controller and the PPM concentration of CO2 will float above 1020 PPM after defeating enrichment equipment (overshoot).
