C7400 Solid State Enthalpy Sensor is used with Honeywell economizer logic modules to proportion outdoor and return air dampers in economizer systems.

  • C7400 solid state elements sense enthalpy (temperature and humidity); use two sensors for differential control, maximizing energy savings.
  • Use one sensor in outdoor air for single sensor control; use two sensors, one in return air and one in outdoor air, for differential control.
  • C7400 mount in any position up to 200 ft (61 m) away from Economizer Logic Module.
  • UL94-5V enclosure.
