sequence
The product’s compressor motor must rotate in the right direction. The
product checks that the phases are connected correctly; otherwise, an alarm
is triggered. This will require changing two of the phases into the product. The
power supply to the system must be shut off when rectifying this fault. This
fault generally only occurs during installation.
