KNX I4-ERD

The KNX I4-ERD evaluation unit monitors ground temperature and humidity. You can control an automatic watering system objectively with the data. Up to four TH-ERD sensors can be connected to the evaluation unit. The two KNX I4-ERD threshold-value dependent switching outputs for humidity and temperature are available for each sensor channel.

KNX I4-ERD evaluation unit receives external readings via the bus and reconciles these to composite values with proprietary data. In this way, you can work with an overall temperature or an overall humidity reading for each channel.

Functions:

• Reception of temperature and humidity information from up to four external sensors
• Composite readings for each sensor channel variable from proprietary measured and external readings (percentage variable)
• 2 thresholds per channel for temperature and humidity, adjustable by parameters or via communication objects
