5. Installation
5.1 Verkabelungsanforderungen
- Ein Neutralleiter ist erforderlich.
- Separate switch legs for the light and fan are needed.
- Ensure the electrical box is deep enough to accommodate the switch.
5.2 Verdrahtungsanweisungen
- Strom ausschalten: Before starting, turn off the power at the circuit breaker or fuse box to avoid electrical shock.
- Drähte identifizieren: Carefully identify the following wires in your electrical box:
- Hot Wire (Line)
- Neutral Wire (Required)
- Load Wire for Light
- Load Wire for Fan
- Erdungskabel
- Kabel anschließen: Use the provided wire nuts to connect the TDHOS5 switch wires to your house wiring according to the wiring diagram.
- Verbinden Sie Rot wire from the switch to the Leichte Ladung Draht.
- Verbinden Sie Blau wire from the switch to the Lüfterlast Draht.
- Verbinden Sie Schwarz wire from the switch to the Hot (Line) Draht.
- Verbinden Sie Weiß wire from the switch to the Neutral Draht.
- Verbinden Sie Grün wire from the switch to the Boden Draht.
- Montieren Sie den Schalter: Gently push the wired switch into the wall box. Secure it with the mounting screws.
- Faceplate installieren: Attach the desired face cover and wall plate.
- Strom wiederherstellen: Schalten Sie den Strom am Leistungsschalter wieder ein.

6. Bedienung
6.1 Erstes Einschalten
Upon initial power-up, the switch will enter a self-test mode. The indicator LEDs may flash. Allow a few moments for the device to initialize.
6.2 Operating Modes (Motion Sensor)
The motion sensor features two operating modes:
- Occupancy Mode (Default): Provides automatic ON/OFF control for both the light and the fan based on detected motion. When motion is detected, the light and fan turn on. After no motion is detected for the set time delay, they turn off.
- Leerstandsmodus: The light must be turned ON manually. The fan operates automatically based on humidity levels or motion detection. After no motion is detected for the set time delay, the light and fan will turn off automatically.
To switch between Occupancy and Vacancy Mode: Press and hold both the light and fan buttons for 10 seconds. The green LED indicator will illuminate solid, indicating the mode has been toggled.
6.3 Humidity Sensor Operation
The humidity sensor monitors ambient humidity levels. When the humidity exceeds the preset threshold, the fan will automatically turn on. The fan will continue to run for the set minimum time or until the humidity level drops below the threshold.

6.4 einstellbare Einstellungen
The TDHOS5 allows for adjustment of time delay and humidity sensitivity:
- Zeitverzögerung: 4 settings ranging from 15 seconds to 30 minutes. Refer to the specific instructions provided with the product for programming these settings.
- Luftfeuchtigkeit: 3 adjustable levels (Low, Medium, High) to set the humidity threshold for fan activation. Refer to the specific instructions provided with the product for programming these settings.

8. Fehlerbehebung
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Light/Fan does not turn ON. | No power, incorrect wiring, sensor obstructed, incorrect mode. | Check circuit breaker. Verify wiring connections. Ensure sensor is clear. Check operating mode (Occupancy/Vacancy). |
| Light/Fan stays ON too long or turns OFF too quickly. | Incorrect time delay setting. | Adjust the time delay setting as per the operation instructions. |
| Fan does not activate with high humidity. | Incorrect humidity level setting, sensor obstructed. | Adjust the humidity sensitivity setting. Ensure the humidity sensor is not blocked. |
| Motion sensor is too sensitive or not sensitive enough. | Sensorplatzierung, Umgebungsfaktoren. | Ensure the sensor has a clear line of sight. Avoid placing near heat sources or drafts. |
| LED-Anzeige funktioniert nicht. | Defektes Gerät. | Contact customer support if all other functions are working correctly. |
