4. Setup and Initial Configuration

4.1. Initial Power-up and Battery Charging

The CN101S timer switch includes a built-in rechargeable battery. Upon first use or after a long period of storage, connect the timer to power for at least 30 minutes to charge the internal battery. This battery maintains the programmed settings and current time during power outages for up to 60 days.

To clear all settings and reset the timer to its default state, insert a small, non-metallic pointed object (like a toothpick) into the 'R' (Reset) hole on the front panel and press gently. The LCD display will show '0:00' and all programs will be erased.

4.3. Setting Current Time and Day

1. Press the Clock button and hold it.
2. While holding the Clock button, press D+ to set the current day of the week (MO, TU, WE, TH, FR, SA, SU).
3. While holding the Clock button, press H+ to set the current hour (0-23 for 24-hour format, or 1-12 for 12-hour format).
4. While holding the Clock button, press M+ to set the current minute (0-59).
5. Release the Clock button. The time is now set.
6. To switch between 12-hour (AM/PM) and 24-hour formats, press the Clock button and P button simultaneously.

4.4. Wiring Instructions

Refer to Figure 3.3 for terminal identification and Figure 3.2 for a simplified wiring diagram. Ensure power is disconnected before wiring.

• Terminals 1 & 2 (Input): Connect your main power supply (LINE and NEUTRAL) to these terminals. For 220V AC, connect the live wire to terminal 1 (LINE) and the neutral wire to terminal 2 (NEUT).
• Terminals 3 & 4 (Output): These are the switched output terminals. Connect the neutral wire of your appliance to terminal 3 (NEUT) and the live wire of your appliance to terminal 4 (LOAD).
• Terminal 5: This terminal is typically for the common neutral connection for the load, often bridged with terminal 3. Consult a qualified electrician if unsure about specific wiring configurations for your application.
