The SPC-2 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 equipment plugged into the two power outlets. The SPC-2 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). NOTE: Depending on individual enclosure characteristics and air circulation as well as location placement of the monitor this factor will vary. The average swing for enrichment response is 50 to 100 ppm which is actually a more desirable enrichment refresh frequency.
