Zehnder EVO Connect KNX
Technical Data
General Features
The Zehnder EVO Connect KNX is an interface for Zehnder EVO mechanical ventilation units with heat recovery.
It enables the connection of Zehnder EVO units to building management systems that utilize the KNX communication protocol. In conjunction with the Zehnder EVO Connect ModBus device, it allows for the configuration of ventilation unit parameters, viewing of errors, and control of the unit's operation.
Communication occurs via RS485 cable between the EVO Connect ModBus device and the building management system.
Controlling the ventilation unit according to user requirements via a third-party building management system ensures maximum comfort in the indoor climate throughout the year.
Features
- Usable with Zehnder EVO controlled mechanical ventilation units and the EVO Connect ModBus device.
- Enables viewing and configuration of all Zehnder EVO ventilation unit parameters.
- RS485 communication with the EVO Connect ModBus and the building management system.
- Allows for setting fan speeds in manual mode and writing scheduling programs or switching to automatic operation mode.
- Quick and easy installation on a 35 mm profile channel.
EVO Ventilation Unit Control
The Zehnder EVO Connect KNX, together with the EVO Connect ModBus, allows for:
- Connecting the Zehnder EVO ventilation unit and all installed sensors (humidity and/or CO2) wirelessly to the KNX building automation system.
- Configuring ventilation unit parameters during commissioning.
- Selecting different fan speeds in manual mode and/or setting scheduling programs using ModBus building automation systems.
- Viewing all system errors via the KNX building management system.
