4. Installation

The HBN BNDS-X2 Digital Timer Switch is designed for easy mounting on a standard 35mm DIN rail within a fuse box or distribution board.

4.1 Mounting on DIN Rail

1. Ensure the main power supply to the distribution board is switched off at the circuit breaker.
2. Locate an available space on the DIN rail.
3. Align the timer switch with the DIN rail and press it firmly until it clicks into place.
4. Ensure the protective cover over the display and buttons is securely in place after installation to prevent accidental adjustments.

4.2 Wiring Diagram

Follow the wiring diagram carefully. Incorrect wiring can damage the device or connected appliances.

• Terminal N (1): Connect to the Neutral conductor.
• Terminal L (2): Connect to the Phase conductor (220VAC).
• Terminal COM (7): Common terminal for the relay. Connect the phase from L (2) to COM (7) if controlling a switched phase.
• Terminal NO (8): Normally Open contact. Connect this to the load (e.g., lamp, appliance). The circuit will be closed when the timer switches ON.
• Terminal NC (6): Normally Closed contact. This terminal is closed when the timer is OFF and opens when the timer switches ON. (Not typically used for standard ON/OFF control).
• Terminals 3 & 4: Test inputs for relay triggering (shorting 3 and 4 will trigger the relay).
• Terminal 5: No function.

After wiring, ensure all connections are secure and insulated before restoring power.

5. Initial Setup

5.1 First Use and Backup Battery

Upon first use, the internal backup battery may be low. Connect the timer to power for at least 30 minutes to charge the battery. This battery retains your programmed settings during power outages.

5.2 Setting Current Time and Day

2. Press the D (Day) button to set the current day of the week.
3. Press the H (Hour) button to set the current hour (24-hour format).
4. Press the M (Minute) button to set the current minute.
5. Press the CLOCK button again to exit time setting mode and save the changes.

The display will show the current time and day. If the display is blank, ensure the device is powered and the backup battery has sufficient charge.

6. Operating Instructions

The timer allows for up to 8 ON/OFF programs with various weekly combinations.

6.1 Programming ON/OFF Times

1. Press the PROG button to enter programming mode. The display will show "1 ON".

3. Press H to set the hour for the first ON program.
4. Press M to set the minute for the first ON program.
5. Press PROG again. The display will show "1 OFF". Repeat steps 2-4 to set the OFF time for the first program.
6. Continue pressing PROG to set up to 8 ON/OFF programs (2 ON/OFF times per program). Each press will cycle through "2 ON", "2 OFF", "3 ON", etc., up to "8 OFF".
7. After setting all desired programs, press the CLOCK button to exit programming mode and return to the current time display.
