ABB ST/K1.1 Actuator electromechanical

The ST/K 1.1 electromotor actuator is a proportional actuator for controlling radiator valves via ABB i-bus®. The actuator is mounted on thermostat valve bases (standard valve adapters VA10, VA78 included in the delivery). It is controlled by a constant EIB/KNX room temperature controller. The actual valve position is indicated by 5 LEDs. In addition, the ST/K 1.1 electromotor actuator has two binary inputs, which can be used, for example, for the connection of a presence contact and/or window contact. The status of these inputs can be sent to the EIB/KNX.
