Features & Benefits

• Unit mounted C7400S enthalpy sensor includes solid state temperature and humidity sensors
• Outputs a digital communicating signal on a two-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
