70310 evaluation unit KNX I4-ERD - irrigation system

Type: ELSNER KNX I4-ERD evaluation unit monitors soil temperature and humidity. With the help of the data, it is possible to specifically control the automatic irrigation system.

Up to four TH-ERD sensors can be connected to the evaluation unit. The KNX I4-ERD provides two switching outputs depending on the limit values for humidity and temperature for each sensor channel. The KNX I4-ERD evaluation unit can receive external measured values via the bus and calculate mixed values using its own data. In this way, one total temperature or one total humidity value can be used for each channel.

Product features
- Receiving information about temperature and humidity from up to four external sensors
- Mixed values from own measured values and external values can be set for each sensor channel (percentages can be set)
- 2 switching outputs for temperature and humidity per sensor channel with adjustable limit values (limit values are set either via parameters or via communication objects)
- Setting via KNX software ETS
