Economizer Sensors

C7400S Enthalpy Sensor

  • Digital enthalpy (humidity/temperature) sensor for use with S-Bus devices
    and W7220 economizer controller
  • This unit mounted C7400S enthalpy sensor includes solid state temperature
    and humidity sensors
  • Outputs a digital communicating signal on a 2-wire Sylkbus communications link,
    reporting the temperature and humidity separately to the controller
  • The controller determines the enthalpy (total heat), enabling economizer modes
    of operation when outside air enthalpy is suitable for free cooling
  • Enthalpy sensors are compatible with Honeywell economizer systems
  • When used with an economizer, the enthalpy boundary curve is programmed
    via the controller
  • When the temperature and humidity are determined to be suitable based on the
    relationship to the boundary, the controller allows outside air for economizing
  • Dual enthalpy sensors in outside air and return switches the controllers to economizer
    mode of operation anytime the outside enthalpy is less than the return air enthalpy
  • Operating temperature range: -40° to 150°F (-40° to 66°C)
  • Maximum ambient temperature: 150°F (65°C)
  • UL Listed component (Guide info XAPX)
