Overview

These stand-alone Carbon Dioxide (CO2) Sensors and Controllers are used for determining ventilation necessity with HVAC controllers and to manage the amount of fresh outdoor air supplied to maintain acceptable levels of CO2 in the space.

Features

  • Models available with LCD that provides sensor readings and status information.
  • Non-Dispersion-Infrared (NDIR) technology used to measure carbon dioxide gas.
  • C7242 provides voltage output based on CO2 and temperature levels.
  • Models available with SPST relay output. Proportional plus Integral (P+I) control algorithm.
  • C7242 output can be configured using optional software package to provide a more complex ventilation control strategy using CO2 levels in conjunction with temperature.
  • Used for CO2 based ventilation control.
  • Automatic Background Calibration (ABC) algorithm based on long-term evaluation reduces required typical zero-drift check maintenance.
  • Digital input with programmable delay time for occupancy function using a sensor, push-button, or switch.
