Incorporates 0-10vDC (over 0-2000ppm by default) CO2 Output + on/off N/O relay rated at 2 amp @24v AC or DC.
CO2 output can be set for a control range output i.e 700-1000 ppm & the onboard relay trigger point is adjustable for local modulating & / or on/off control of EC fan or damper motor for local CO2 control, and is an ideal low-cost sensor for direct fresh air co2 control requirements negating the need for a controller if only CO2 control is required.
