Zehnder EVO Connect ModBus
Technical Specifications
General Features
The Zehnder EVO Connect ModBus allows you to connect your Zehnder EVO ventilation unit to a building automation system using the ModBus communication protocol.
It enables the integration of the ventilation unit itself, as well as any additional Zehnder EVO series wireless control devices, such as humidity and CO2 sensors, into your BMS.
All data is transmitted wirelessly, eliminating the need for extra wiring to the EVO Connect ModBus, which in turn connects to the building management system via RS485.
This setup allows for demand-driven ventilation control, based on detected environmental conditions or user preferences, enabling users to program and control the entire system through home automation. These capabilities help maintain maximum comfort and achieve optimal energy savings year-round.
Key Features:
- Compatible with Zehnder EVO mechanical ventilation units.
- Status indicator LEDs and a reset button.
- Simple and user-friendly installation.
- Wireless communication with Zehnder EVO ventilation units and RS485 communication with the building management system.
- Allows for parameter programming during startup and control of ventilation speeds and settings during normal operation.
- Power supply: 24 VAC/DC.
- Quick and easy wall mounting in a 502 or round wall box.
