5. Nastavení a instalace
5.1. Montáž
The Walfront TM919B-1 timer switch is designed for 35mm DIN rail mounting. Simply clip the device onto a standard DIN rail within your electrical panel or enclosure.

5.2. Zapojení
WARNING: Ensure power is OFF at the main circuit breaker before performing any wiring.
The timer switch has five terminals:
- Terminály 1 a 2: Power input for the timer module (AC 100-130V). Connect the Live (L) wire to terminal 1 and the Neutral (N) wire to terminal 2.
- Terminál 3: Common (COM) terminal for the relay output.
- Terminál 4: Normally Open (NO) terminal for the relay output. The circuit between 3 and 4 closes when the timer is ON.
- Terminál 5: Normally Closed (NC) terminal for the relay output. The circuit between 3 and 5 opens when the timer is ON.
Choose the appropriate wiring diagram based on your application:

Image 5.2: Simple Wiring Diagram. This diagram shows a direct connection of the timer switch to a light bulb. The Live (L) and Neutral (N) wires power the timer (terminals 1 and 2). The Live wire is also connected to terminal 3 (Common). Terminal 4 (Normally Open) is connected to one side of the light bulb, and the other side of the bulb is connected to Neutral (N).
For loads exceeding the timer's direct capacity (30A/5000W) or for inductive loads, an external contactor (relay) must be used. The timer switch will then control the coil of the contactor, and the contactor will switch the main load.

Image 5.3: Wiring Diagram with Contactor. This diagram illustrates how to wire the timer switch with an external contactor to control a higher-power load. The timer's output (terminals 3 and 4) is used to energize the coil of the contactor. The contactor then switches the main power to the load (e.g., a light bulb), ensuring the timer itself is not overloaded.
5.3. Počáteční zapnutí
After wiring, restore power to the circuit. The LCD display should illuminate. If the display is blank or shows garbled characters, press the RESETOVAT button using a pointed object (e.g., a pen tip) to clear the memory and restart the device. The internal CR2450 battery provides memory backup for programmed settings during power outages.
