Alarm messages
If a fault occurs with e.g. a sensor, an alarm is triggered. A message appears on the display
with information about the fault.
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. A persisting fault must first be rectified
before it can be reset. Some alarms are reset automatically if the fault ceases.
Alarm messages
Description
[E055] Wrong phase order
The compressor motor in the connected heat pump must rotate in the right
direction. The heat pump checks that the phases are connected correctly; if
not, an alarm is triggered. In this case, two of the phases to the heat pump
need to be changed. The power supply to the heat pump must be switched
off when rectifying this fault. This fault generally only occurs during installation.
[Exxx] sensor
An alarm is displayed if a fault occurs with a sensor that is not connected
or has short-circuited and if the value is outside the sensor’s range of
measurement. If this sensor is significant to the system’s operation, the
compressor of the heat pump stops. This requires the alarm to be reset
manually after the fault has been rectified. For the sensors below, the alarm is
reset automatically after correction:
