H98Outdoor high pressure overload protection

Name in the manufacturer's documentation (service manual): Outdoor high pressure overload protection[1]

In plain words (editorial)

In heating mode the refrigerant pressure is too high and the overload protection stopped the unit. The service manual lists the water pump among the causes, and notes that a reset does not help if the cause is not repaired.

When to call a service technician: Call the installer if the code repeats.
