Hi,
Flowcon heating actuators on a 0-10 volt dc supply seem to be picking up voltage. It's on a knx system, and the switch actuator calls for 0-10 volts dc based on 0-100 %. The cable used is a screened 4 core. Though only using 3 cores as follows -0volts ground, 24volts dc to drive actuator, 0-10volts dc to tell actuator how much to open. Rooms are overheating , any ideas?
