Your Step-by-Step Guide to Programming an Intermatic Digital Timer

While specific steps can vary by model, the core process for programming your Intermatic digital timer is generally consistent across most units. Think of it as teaching your timer its daily routine.

Initial Setup: Time, Date, and Zone

Before you can set schedules, your timer needs to know when it is.

1. Set Current Time and Date: Most models require you to enter the current month, day, and year using “Mode,” “Plus,” “Minus,” or “Enter” buttons. Pay close attention to AM/PM settings.
2. Daylight Saving Time (DST): Many Intermatic digital timers feature automatic DST adjustment. Ensure this setting is enabled if your region observes DST.
3. Astronomic Zone: For timers with astronomic features, you’ll select your geographic zone (e.g., North, Central, South). This allows the timer to calculate precise dawn and dusk times for your location.

Creating ON/OFF Schedules

This is where the magic happens, telling your devices when to spring to life and when to rest.

1. Enter Programming Mode: Typically, this involves pressing a “PROG” or “MODE” button until “ON/OFF EVENTS” appears.
2. Set ON Event: Choose the event number (e.g., “Prg 1 ON”). Use “DAY,” “HOUR,” and “MIN” buttons to select the desired days (e.g., Monday-Friday, weekends, specific days, or every day) and the exact time you want the device to turn ON.
3. Set OFF Event: After setting the ON time, the display will usually advance to the corresponding OFF event (e.g., “Prg 1 OFF”). Repeat the process to set the OFF time and days.
4. Multi-Circuit Timers: If your timer controls multiple circuits, you might need to select which “LOAD” (circuit) each event applies to.
5. Save and Exit: Once all events are programmed, save your settings and ensure the timer is in “AUTO” mode for the schedule to take effect.

Advanced Features: Astronomic & Random Modes

These features elevate your timer’s intelligence and utility.

• Astronomic Mode: Instead of fixed times, you can program events relative to sunrise or sunset. For example, your landscape lights can turn ON 30 minutes before sunset and OFF at midnight, automatically adjusting throughout the year.
• Random Mode: This security feature subtly shifts your programmed ON/OFF times by a few minutes (e.g., +/- 15 minutes). It’s a fantastic way to deter burglars who might otherwise notice predictable lighting patterns.
