2. Plug In Timer: Insert the 3-prong grounded plug of the HB112 timer directly into a compatible 240-volt wall receptacle.

Operating Instructions

Setting ON/OFF Times

The timer allows for up to 2 ON and 2 OFF settings per 24-hour period using the black push segments (pins) around the dial.

1. Identify Pins: The dial has small black segments. Each segment represents 15 minutes.
2. Set ON Time: Push down the segments corresponding to the desired time you want the appliance to turn ON. For example, to turn ON at 6:00 AM, push down the four segments between 5:45 AM and 6:00 AM.
3. Set OFF Time: Pull up the segments corresponding to the desired time you want the appliance to turn OFF. For example, to turn OFF at 8:00 AM, pull up the four segments between 7:45 AM and 8:00 AM.
4. Minimum ON/OFF Duration: Ensure a minimum of 45 minutes between ON and OFF settings for reliable operation.

Manual Override

The HB112 timer includes a manual override switch, typically located on the side or bottom of the unit. This switch allows you to temporarily bypass the programmed settings.

• ON Position: Move the switch to the 'ON' position to keep the appliance continuously powered, regardless of the dial settings.
• OFF Position: Move the switch to the 'OFF' position to keep the appliance continuously off, regardless of the dial settings.
• TIMER Position: Move the switch to the 'TIMER' position to allow the programmed ON/OFF cycles to operate.

Maintenance

• Storage: Store the timer in a dry, cool place when not in use.
• No User-Serviceable Parts: Do not attempt to open or repair the timer. Refer servicing to qualified personnel.

Troubleshooting

• Appliance does not turn ON/OFF at programmed times:
  • Ensure the manual override switch is set to 'TIMER'.
  • Verify that the current time on the dial is correctly aligned with the present time.
  • Check that the ON/OFF segments (pins) are correctly pushed down or pulled up for the desired times.
  • Confirm the appliance is properly plugged into the timer and is functioning correctly.
• Timer stops operating after a power outage:
  • This mechanical timer does not have an internal battery backup. After a power outage, you must manually reset the current time on the dial.
