S-Bus Digital Enthalpy Sensor

ITEM NUMBER : C7400S1000-U | Universal Parts

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 two-wire Sylk Bus 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
Ambient temperature operating range from -40° to 150° F
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
