Gira Servo 3 KNX Control Drive - 217600

The Gira KNX actuator control valve bus system is a radiator valve with IP20 protection degree and nominal voltage of 230V. It features an electromechanical actuator with two binary inputs intended for mounting on thermostat valve bases for controlling heating or cooling systems. It can be used for room temperature control on various systems and is equipped with integrated bus coupler, temperature sensor and room temperature controller. Additionally, the actuator recognizes and displays valve stroke and is powered by the KNX system. It also has one input that can function as a binary input or can be connected to an external temperature sensor. The actuator is capable of switching, dimming, shutter control, and can function as value transmitter. It includes a function for protection against stuck valves, monitoring of the control signal, actuator error reporting, and emergency operation via internal temperature sensor. Adapters needed for valve bases from other manufacturers.
