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
