Product overview
This transmitter uses NDIR CO2 sensing technology operates in accordance with the single-beam,
dualwavelength method. The temperature calibrated sensor has unique reference measurement capabilities,
offering excellent stability over both time and temperature.
It requires a 15..35 VDC or 19..29 VAC power source and generates an output signal proportional to the CO2
level detected.
SCD can operate in support of Demand Control Ventilation (DCV), with fresh air and Indoor Air Quality (IAQ)
systems, with rooftop air handling Economizer controls systems, in Standalone applications or as part of any
integrated Building Automation strategy.
Using the CO2 transmitter results in considerable savings in installation, operation, and maintenance costs with
no recalibration expenses. Johnson Controls CO2 transmitters, when used with BAS/Economizer controllers
(featuring DCV strategies), can generate energy savings ranging up to:
• 20 to 40% in office buildings
• 20 to 60% in restaurants/light retail facilities
• 10 to 70% in educational/business settings
