7. MAINTENANCE AND REPAIRS
Under normal conditions, a suitable heat pump can heat up the tub water by 1°C to 2°C per
hour. It is therefore normal that you do not feel any difference in temperature at the outlet
level when the heat pump is on.
A heated tub must be covered and insulated to avoir any heat loss.
7.3 Breakdown and faults
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 find the possible causes of a fault and the actions to
be taken.
Code
E01 Discharge temperature failed
E05 Coil temperature failed
E09 Suction temperature failed
E19 Water inlet temperature failed
E21 Controller communication failed
E22 Ambient temperature failed
E25 Water flow switch failed
Communication failed between PCB and
E27
compressor driver
E28 EEPROM communication failed
S06 Low voltage protection
S11 Discharge temperature too high protection
S25 Ambient temperature too low protection
S27 Coil temperature too high protection
