Main Fuse Tripping — Electrical overload in the property

What does Main Fuse Tripping mean?

The property's main fuse may trip if the heat pump's electrical addition operates simultaneously with many other high-power consumers. The F750 has integrated load monitors, but an overload can still occur.

• Simultaneous high power consumption from multiple appliances and the heat pump's electrical addition
• Incorrect main fuse size setting in the heat pump menu (Menu 5.1.12)

Click steps to track your progress.

1. 1

   Reduce the number of high-power appliances operating simultaneously in the property.

2. 2

   Check the size of the property's main fuse in menu 5.1.12 of the heat pump's system and ensure it matches the actual fuse installed.

3. 3

   Consider installing current sensors on incoming phase conductors if not already present, to allow the heat pump's load monitor to function optimally.

4. 4

   If persistent, consult a qualified electrician to assess the electrical installation and fuse sizing.
