Honeywell C7040 Enthalpy Sensor, -40 to 150 deg F, 7 - 21 VDC, 10 - 90% RH Humidity, 2-Pin Header-Pin Style Or 2-Pin Card Edge Removable Terminal Blocks, Any Position Mount, Gray, 4.25 Inch H x 2.17 Inch W x 0.81 Inch D
- Digital enthalpy (humidity/temperature) sensor for use with S-Bus devices and W7220 economizer controller
- 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
