HA / HF flashing — Alarm for temperature deviation or power failure

What does HA / HF (flashing) mean?

When 'HA' or 'HF' flashes on the display, it signals an alarm condition, such as the appliance's internal temperature being too high or too low, or a past power failure event.

• Appliance temperature too high
• Appliance temperature too low
• Power failure occurred

1. 1

   Press the alarm acknowledgement button to stop the flashing display and quiet the audible warning.

2. 2

   Query the stored alarm events (HAn) to determine the specific cause, such as temperature deviation or power failure details.

3. 3

   Reset the stored alarm events by pressing the required buttons (e.g., '+' and '-' simultaneously for 5 seconds) to clear the 'HA' or 'HF' message and prepare the system for new alarms.

   If the alarm was due to temperature, ensure the door is closed properly and product loading is correct. If a power failure, verify a stable power supply.
