Code Description Status Solution
S08 Defrost error
Compressor
stopped
If the system fails to finish the defrost process 3 consecutive times, it stops
and the error message S08 appears. Remove and restore electricity to reset
the error. Check that the water temperature is not too cold, in case the plate
heat exchanger could break.
S09
Supply water temperature error, too
cold in heating or DHW production
Compressor
stopped and
electric heater
in operation.
The error appears if the unit is stopped but the electric heater is running
and the supply water temperature is below 15 ° C during heating or DHW
production mode. The compressor restarts when the supply temperature
exceeds 17 ° C. This function is to avoid damage to the compressor.
S10 Water flow too low error
Compressor
stopped
If the unit stops due to error S2 (water flow too low) 3 times in a certain
period of time it will re-lock and S10 will appear. Remove and restore the
electrical supply to reset the error. Check the hydraulic circuit, especially the
filter. Check the proper functioning of the pump.
S11 Defrost antifreeze protection error
Compressor
stopped
If the unit stops due to error S1 (antifreeze protection in cooling) 3 times in a
certain period of time it will re-lock and S11 will appear. Remove and restore
the electrical supply to reset the error.
S12
“Floor curing” function not achieved
(N/A)
(N/A) (N/A)
S13 4 way valve blocked
Turn the unit off and on again. If the error is repeated immediately, the 4-way
valve is blocked and must be replaced.
S14 3 way valve position error
Check that the 3-way valve works correctly. Check that the Tw and Tc sensors
are not reversed. When the compressor has been running for more than 5
minutes, if Tw-TUI> 12 (for more than 2 min) in DHW or if Tc-TUI> 12 (for
more than 2 min) in heating, the unit will go into error S14 .
