Use with C7400A, or C7660 and C7150B or C7046 Sensors; Demand Control Ventilation (DCV) sensor C7232 C02 sensor (2-10 Vdc); and Honeywell Series 72 actuators, or M7415 Damper Actuator to proportion outdoor and return air dampers for economizer and ventilation control in commercial HVAC equipment. (See below)

  • Input from DCV C02 sensor provides optimum ventilation based on occupancy.
  • All models include air change and shutdown; "A" models also provide prepurge.
  • Demand control ventilation economizer provides comfort, energy savings, reliability, air quality compliance and application flexibility in heating, cooling and ventilating applications.
  • Combines solid state enthalpy or dry bulb changeover control, minimum and maximum damper position potentiometer and DCV setpoint functions.
  • Optional differential enthalpy control (enthalpy setpoint D with two C7400A sensors) provides greater economizer savings and maximum comfort over single enthalpy control by selecting the most economical method for cooling.
  • Enthalpy setpoint (A-D) on economizer module controls the combination of air temperature and humidity that is suitable for free cooling.
  • LEDs indicates when economizer is in free cooling and DCV modes.
  • B models provide for input from an outdoor air quality sensor.
