Operating Instructions

The HB35K timer uses a mechanical dial with captive trippers for programming and a manual override switch.

Setting the Current Time:

1. Rotate the entire timer dial clockwise until the current time aligns with the arrow indicator (usually marked "TIME" or a small triangle) on the stationary part of the timer. The dial is marked with 24 hours (1-12 AM, 1-12 PM).

Programming ON/OFF Times:

The timer has captive trippers around the dial. Each tripper represents a 30-minute interval.

1. To Set ON Time: Push down the trippers corresponding to the desired ON period. When a tripper is pushed down, the connected device will be ON during that 30-minute interval.
2. To Set OFF Time: Leave the trippers in the UP position for the desired OFF period. When a tripper is up, the connected device will be OFF during that 30-minute interval.

Using the Manual Override Switch:

The timer features a manual override switch, typically a small lever or button, with three positions: "I" (ON), "T" (Timer), and "O" (OFF).

• "I" (ON): Moves the timer to a continuous ON state, overriding the programmed settings.
• "T" (Timer): Activates the programmed ON/OFF schedule. This is the default position for automated operation.
• "O" (OFF): Moves the timer to a continuous OFF state, overriding the programmed settings.

To return to programmed operation, ensure the switch is set to the "T" position.

Maintenance

The Intermatic HB35K timer requires minimal maintenance. Follow these guidelines to ensure longevity:

• Cleaning: Disconnect the timer from the power source before cleaning. Wipe the exterior with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Inspection: Periodically inspect the power cord and plug for any signs of damage, fraying, or corrosion. If damage is found, discontinue use and replace the unit.
• Environmental Protection: While designed for outdoor use, prolonged exposure to extreme weather conditions (e.g., heavy rain, snow, direct sunlight) can reduce its lifespan. Consider additional protection if installed in highly exposed areas.
