The electromechanical actuator ST/K1.1 is a proportional actuator for controlling radiator valves via ABB i-bus®. The actuator is mounted on thermostat valve bodies (common valve adapters VA10, VA78 included in the delivery). Control is carried out via a continuous EIB / KNX room temperature controller. The actual valve position is indicated by 5 LEDs. Furthermore, the electromechanical actuator ST/K1.1 has two binary inputs, which can be used, for example, for connecting a presence detector and/or window contact. The status of these inputs can be sent to the EIB / KNX. EAN: 4016779630221.
