Code Description
F0 This flashes at around 2000 operational
hours of the pump to indicate that it is
necessary to clean the filter.
F3 In heating mode, at an outside
temperature of 7ºC, the pressure reached is
higher than 35 bars.
F4 In heating mode, at an outside
temperature of 20ºC, the refrigerant low
pressure is below 3 bar
F5 Water flow lacking: an initial fault has been
found. Repetition of the F5 fault will stop the
device (code h2)
F6 Antifreeze fault: an initial fault has been
found. Repetition of the F6 fault will stop the
device (code h4)
F9 The sensor measured an initial pressure
excess. 3 detections produce an h0 block-
age. An h0 code may be produced either by
3 high pressure detections in less than an
hour (P>42 bar), or by a triggering of the
pressure switch (P>42 bar).
