The Busch-Wächter® Presence EIB is designed for indoor use in offices, schools, and private buildings. It controls lighting and HVAC systems based on brightness and/or movement. The device supports both flush-mounted and surface-mounted installations. It features sensitive sensors and can be configured via ETS or manual potentiometers. Installation height affects its functionality, and the detection range can be adjusted using a supplied foil. Refer to the "Busch-Wächter® Presence" user manual for detailed application examples and information.
Troubleshooting and error codes
| Symptom | Cause/Action | |
| The load is not operated at all: | - Replace defective load - Replace fuse/reconnect - Replace damaged conductor - Check connections to the respective flush-mounted insert - Replace device if necessary | |
| The motion detector does not react: | - Check potentiometer settings - Clean dirty lens - Light threshold value too low - increase - Check/move heat sources in the room. Possibly cover parts of the lens system with foil. | |
| The motion detector reacts without movement in the room: | - Movement is too small to be detected - Increase the switch-off delay time with the "Time" potentiometer | |
| Setting changes of the three potentiometers are not accepted: | - Value has been set via ETS. Activate via the "Settings" menu, "Poti" setting instead of "ETS" | |
| Motion detector as constant light regulator | Symptom | Cause/Action |
| The motion detector does not close the circuit: | - Too much daylight, adjust threshold value | |
| The motion detector does not regulate to the desired brightness level: | - No target value stored, set a target value |
