Description of operation

The AKM 115SA Smart Actuator is an integrated combination of a freely programmable automation

station (AS) and a ball valve actuator. Without additional controllers, it enables self-sufficient, energy

optimised control to be set up in primary systems or individual rooms. Together with an ecoUnit room

operating unit and up to two additional SAIO 100 I/O modules, even complex HVAC systems or room

controls can be implemented.

For system integration and programming, the Smart Actuator can be accessed via the communication

interfaces Bluetooth LE, WLAN and RS-485 with BACnet MS/TP.

The application programming is performed with SAUTER CASE Suite. Finished applications can be

stored in the SAUTER Cloud and loaded onto the Smart Actuator from there. Commissioning, access

to application visualisation, and documentation are carried out using SAUTER CASE Suite tools via a

mobile app or via the web interface in the SAUTER Cloud. As an IoT device, the Smart Actuator

connects to the SAUTER Cloud IoT hub via the integrated WLAN interface. The data transmission,

encrypted using TLS, is performed via the MQTT protocol. The Smart Actuator can be integrated into

a building automation network via BACnet MS/TP as an application-specific controller (B-ASC).

The Smart Actuator can be combined with 2-, 3- and 6-way ball valves. It is fitted without force by

means of a bayonet connector. Manual adjustment is performed by disengaging the gears (push

button on the actuator housing) and turning the lever. After the release button is let go, the actuator

remains at the current position and is in “local priority operation” mode (the LED alternately flashes

green and orange rapidly). After the button on the actuator is pressed for more than 5 seconds, the

actuator returns to normal operation and moves to the current position setpoint. The actuator position

is measured via the electromechanical travel measurement system and can be read out via the
