Overview:
The H705 Solid State Enthalpy Controller maximizes the use of free outdoor air in place of the first stage of cooling in heating, ventilating and air conditioning (HVAC) economizer systems.

Features:

  • Consists of a W7459A type solid state economizer logic module and a C7400A Solid State Enthalpy Sensor on a mounting plate.
  • Mounts in any position in outdoor air duct.
  • Use enthalpy setpoint to select desired combination of air temperature and humidity.
  • Use a second C7400A Sensor for differential changeover control to maximize savings.
  • Maximizes use of outdoor air for free cooling.
  • Use in electronic and electromechanical systems.

    SPDT - terminals 1 and 2 make with enthalpy increase above setpoint; terminals 2 and 3 make with enthalpy decrease.
