8.2 Alarm messages
If a fault occurs with a sensor, for instance, an alarm is triggered. A message
appears on the display with information about the fault. In the event of an
alarm, the LEDs on the display and room sensor also l ash.
You reset the alarm by pressing the “Reset alarm” button on the display.
If several alarms are triggered, they are displayed one after the other. An
outstanding fault cannot be reset without being rectii ed i rst. Some alarms
are reset automatically if the fault disappears.
Alarm Text Description
Wrong phase order compressor
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. In this case, two of the phases to the product need to be
changed. The power supply to the system must be shut off when rectifying
this fault. This fault generally only occurs during installation.
Alarm sensor
An alarm is displayed if a fault occurs with a sensor that is not connected or
has short-circuited. If this sensor is signii cant to the system’s operation, the
compressor stops. In this case, the alarm is reset manually after the fault
has been rectii ed.
