Regio Ardo

Regio Ardo is a configurable 24 V zone controller. One controller is able to control two different zones.

It is quick and easy to commission. The I/O configuration and application setup for a VAV controlled room are predefined and the room units ED-RU are easily connected.

The controller is compatible with other Regin products and can easily be integrated into larger systems.

The controller can be used in systems with communication, e.g. EXOline, Modbus or BACnet (over RS485 or TCP/IP). It is installed in a ceiling void, on a junction box plate or on a DIN-rail.
