C7400S Enthalpy Sensor
- 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 2-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 - Operating temperature range: -40° to 150°F (-40° to 66°C)
- Maximum ambient temperature: 150°F (65°C)
- UL Listed component (Guide info XAPX)
