Contemporary I&C building automation

Air. Water. Fire & Smoke. All controlled digitally.


An itaMAX-based building control system with Gruner VAV control components saves up to 70% more energy than conventional mechanical ventilation systems – not only in new properties but also in the upgrading and renovation of existing building stock. The itaMAX system can be integrated in existing building management systems using standardised interfaces and protocols. Optionally, fans are activated by an analogue system or via Modbus RTU. When using Modbus RTU, up to 240 supply and exhaust air controllers can be connected up to the same line. All this needs is to set the fan parameters – itaMAX then automatically takes over operation. This dispenses with the time-consuming effort of defining the parameters for individual functions. Network diagnostics enable parameterisation, remote diagnosis and remote maintenance to be performed via a web interface.

Measurement, control and regulation in the smart way

Gruner can provide planners and architects with actuators for building automation and building management that are efficient, that are easy to integrate and that perform their function reliably to state-of-the-art technical standards.

Gruner standard range

Ideal for stairwells

For all requirementsEquipped

The Gruner standard rotary actuators 227 and 363 without spring return as well as 341 and 361 with spring return cover the full range of requirements within a building. These reliable actuators provide the basis for a comprehensive range of field devices. They are used as a standard in classic ventilation construction. In addition, they provide the ideal platform for developing individual variants for specific solutions.

328QS super-fast running actuatorsWith fail-safe

With its automatic return function, the 328QS actuator is predestined for use in laboratories and public-sector buildings that are obliged to comply with current European safety directives.
