ABB 2CDG120004R0011 ST/K1.1 Electric actuator AP

The electromotive actuator ST/K 1.1 is a proportional actuator for controlling radiator valves via ABB i-bus®. The actuator is mounted on thermostat valve bottom parts (accessible valve adapter VA10, VA78 included). The control takes place via a steady EIB / KNX room temperature controller. The actual valve position is indicated by 5 LEDs. Furthermore, the electromotive actuator ST/K 1.1 has two binary inputs which can be used, for example, for connecting a presence contact and/or window contact. The status of these inputs can be sent to the EIB / KNX.
