It holds a fixed 20 ppm hysteresis, so at a 1000 ppm target it runs until roughly 1020 ppm. A large LED shows real time ppm and an orange LED marks active enrichment. An elevation setting improves accuracy at altitude. Wiring CO2 Enrichment to the SPC 2 Plug your CO2 generator or regulator solenoid into an
