Frequently Asked Questions - HB112 INTERMATIC

How do I install the Intermatic HB112 timer switch?

Turn off power at the circuit breaker. Remove the existing wall plate and switch. Connect the wires to the screw terminals: black (line), red (load), white (neutral), and green (ground). Mount the timer into the wall box and attach the wall plate. Restore power and set the time.

How do I set the current time on the HB112?

Rotate the dial clockwise until the arrow points to the current time. Do not rotate counterclockwise, as it may damage the mechanism.

How do I program on/off times?

Push the trippers (small plastic tabs) outward to set the ON time and inward to set the OFF time. Each tripper corresponds to one hour. Place them at the desired times around the dial.

What is the maximum load the HB112 can handle?

The HB112 is rated for 15 A at 125 V AC, which is 1875 W for resistive loads. For inductive loads (motors), derate to 80% (12 A).

Why is my timer not turning on/off at the set times?

Check that the trippers are pushed fully in or out and are not loose. Ensure the dial is turning freely. If the power was interrupted, the timer may need resetting. Also verify the wiring is correct.

Can I use the HB112 outdoors?

No, the HB112 is designed for indoor use only. Exposure to moisture or extreme temperatures may cause failure.

How do I clean the timer?

Use a dry, soft cloth to wipe the surface. Do not use water, cleaners, or abrasive materials, as they may damage the plastic.

Does the HB112 have a backup battery?

No, the HB112 does not have a battery backup. If power is lost, the timer will stop and must be manually reset to the correct time when power returns.

What wire gauge should I use for installation?

Use solid copper wire of 14 AWG to 12 AWG. Do not use aluminum wire or stranded wire without ferrules.

Are replacement trippers available for the HB112?

Yes, replacement tripper sets can be purchased from Intermatic or authorized dealers. Order part number 15600 for a set of 10 trippers.
