In the event of a problem, the heat pump’s screen displays an error code instead of temperature
indications. Please consult the table below to nd the possible causes of a fault and the actions to
be taken.
6.1 Breakdowns and faults
WARNING: Under normal conditions, a suitable heat pump can heat the water in
a swimming pool by 1°C to 2°C per day. It is therefore quite normal to not feel any
temperature di󰀨erence in the system when the heat pump is working.
A heated pool must be covered to avoid any loss of heat.
