Setup and Installation

Important Safety Information: Installation should only be performed by a qualified electrician or a knowledgeable individual familiar with electrical wiring. Always turn off power at the circuit breaker before beginning any electrical work to prevent electric shock.

Wiring Requirements:

• Neutral Wire: A neutral wire is required for the operation of this switch. This is typically found in newer homes.
• Voltage: 120VAC.
• Maximum Fan Load: 3A.
• Single-Pole Use Only: This switch is designed for single-pole applications.

Installation Steps:

1. Turn Off Power: Locate the circuit breaker controlling the fan circuit and turn it OFF. Verify power is off using a voltage tester.
2. Remove Old Switch: Carefully remove the existing wall plate and switch from the electrical box.
3. Identify Wires: Identify the Line (hot), Load (to fan), Neutral, and Ground wires. The TDHS5 requires a neutral wire.
4. Wire the Switch: Connect the wires to the TDHS5 switch terminals according to the wiring diagram provided with the product packaging. Ensure all connections are secure.
5. Mount the Switch: Gently push the wired switch into the electrical box and secure it with screws.
6. Install Wall Plate: Attach the new wall plate.
7. Restore Power: Turn the power back ON at the circuit breaker.

Operating Instructions

Automatic Humidity Control:

The TDHS5 switch will automatically activate the connected ventilation fan when it detects that the humidity level in the room exceeds the preset threshold. The fan will continue to run until the humidity drops below this level, after which it will turn off with a 20-minute time delay.

Adjusting Humidity Sensitivity (45%-80% range):

The switch offers three levels of humidity sensitivity: Low, Medium (default), and High. To change the setting:

1. Step 1: Press and hold the fan button for 8 seconds until the fan indicator light illuminates. This indicates entry into the setting mode.
2. Step 2: Press the fan button again to cycle through the modes:
   • Press once for Low sensitivity.
   • Press twice for Medium sensitivity (default).
   • Press three times for High sensitivity.
3. The selected setting will be saved automatically after a few seconds of inactivity.

Manual ON/OFF Operation:

To manually turn the fan ON or OFF, simply press the fan button. This will override the automatic humidity sensing until the next humidity cycle or manual intervention.
