🌞 Daylight Saving Time: How to Change the Clock on Your Fujitsu General or Mitsubishi Electric Air Conditioner

Twice a year, Daylight Saving Time (DST) gives us a reminder to “spring forward” or “fall back” — and while many devices adjust automatically, your air conditioner remote control or wall controller may not. If you're using a Fujitsu General or Mitsubishi Electric air conditioning system, updating the internal clock is important for keeping your scheduled settings (like timers or energy-saving modes) running properly.

Here’s everything you need to know to stay on time and comfortable.

⏰ Why You Should Update Your Air Conditioner’s Clock

Both Fujitsu General and Mitsubishi Electric systems often use built-in timers or schedules for:

• Turning the unit on before you get home
• Switching off automatically while you sleep
• Managing energy usage throughout the day

If the clock is an hour off due to DST, your air conditioner could turn on too early, shut off too late, or completely miss your programmed times.

🔄 When Does Daylight Saving Time Start and End?

Daylight Saving Time typically:

• Begins: The first Sunday in October (clocks go forward 1 hour)
• Ends: The first Sunday in April (clocks go back 1 hour)

Note: These dates apply in Australia.

🛠 How to Change the Clock on a Fujitsu General Air Conditioner

There are different remote models, but here’s a general guide:
Using the Standard Wireless Remote:
1. Press the “Clock” button (sometimes labeled “Time”).
2. The clock display will start flashing.
3. Use the arrow keys (▲/▼) to set the correct hour.
4. Press “Set” or “Clock” again to confirm.
📝 Tip: Make sure you’re setting the correct AM/PM if your model doesn’t use 24-hour time.

1. Press the Menu button.
2. Scroll to Clock Setting or Timer Settings.
3. Adjust the time using the dial or arrows.
4. Press Enter or Set to save the time.

🛠 How to Change the Clock on a Mitsubishi Electric Air Conditioner

Mitsubishi Electric systems come with either a handheld remote (like the PAR or PAC series) or wall-mounted controllers.

Using a Handheld Remote

1. Press the Menu button.
2. Navigate to Clock or Time Setting.
3. Use the ▲/▼ buttons to set the correct time.
4. Press Enter or Set to confirm.

Using a Wall-Mounted Controller (e.g., PAR-40MAA):
1. Tap the Home/Menu button.
2. Select Schedule > Clock Setting.
3. Adjust the time using the touchscreen or control knob.
4. Confirm and exit.

✅ Final Check: Are Your Timers Still Accurate?

After adjusting the clock:

• Review your weekly or daily timer settings.
• Make sure ON/OFF times reflect your updated schedule.
• Test a timer if you're unsure it's working correctly.
