Malfunction
The device is not • No display
operational • The pool temperature is above the set-
• A message is displayed on the screen
• Absent or inadequate water flow-rate
• The parameter «on/off ctrl» is on «yes»
The device is • Inadequate filtering time
operational, but • Non-compliant period of use
water temperature • The heat pump is under-dimensioned
fails to rise • The automatic pool water filler is
• The heat insulating cover is not used
• The evaporator is clogged
• The device is incorrectly installed
• A message is displayed on the screen
The fan is turning, • The heat pump does defrost cycles
but the compressor
stops from time • The evaporator is clogged
to time without
an error message
appearing
The heat pump • The circuit breaker rating is too low or
makes trip the
circuit breaker • The cable cross-section is too small
• The supply voltage is too low
• Voltage drops when the compressor is
• Varistor(s) VA1 and/or VA2 is/are out of

order
In order to • Protect the pool with a cover (floating cover, roller cover, etc.), to avoid
improve the heat loss
efficiency of • Choose periods when the outside temperature is warm (on average
your heat > 10°C) in order to facilitate the temperature increase (this may take
pump it is several days. The actual time will vary according to weather conditions
recommended and the power of the heat pump)
that you: • The higher the ambient air temperature, the more efficient the heat
pump will be
• Keep the evaporator clean
Check that • During the heating phase, water flow must be continuous (24/24)
filtration time • To maintain the temperature throughout the season, allow for
is sufficient "automatic" flow of at least 12 hours/day (the longer automatic flow is
used, the more time the heat pump will have to function and to heat the
water)
Setting the set-point to maximum will not heat the water any faster.
• On start-up the device remains on «pause» for 3 minutes before actually starting up: check
that this period has passed
• Once the pool has reached the set-point temperature, the heat pump switches off: check
that the water temperature is lower than the requested temperature (see §3.2)
• If the water flow-rate is zero or inadequate, the heat pump will stop: check that water is
flowing correctly through the heat pump, and check the hydraulic connections
• When the outdoor air temperature drops below 5 or -8 °C, the heat pump will stop: check
the outdoor temperature
• The heat pump may have detected a malfunction: check if an error code is displayed on
the screen, if so refer to §5.1
• If the problem persists after you have checked all of the above points: contact your
installer
Solutions
• Check the supply voltage and the fuse F1
• Increase the set-point temperature
• Check the meaning of message §5.1
• Check the water flow-rate (by-pass, filtration)
• Shunt the bornes7-8 and modifiy the parameter
on «No» (see §2.4.4 «Remote on/off control»)
• Set the filtering system to manual 24- hour
operation for temperature control
• Check that outdoor temperature is within the
operating range (see §1.3)
• Check the characteristics of the heat pump
according to the pool
• Check the correct operation of the automatic
filler
• Fit the heat insulating cover
• Clean the evaporator (see §4.1)
• The device must be installed outdoors.
• Check that there is no obstacle less than 4 metres
from where the blower is facing, and 0.50 metres
behind the heat pump (see§2).
• Check the meaning of message §5.1
• This is normal if the outdoor temperature is below
10 °C
• Clean the evaporator
• Check the circuit breaker (see § 2.4.3).
• Check the cable cross-section (see § 2.4.3)
• Call your electricity provider
• Add a soft starter for models M5, MD5 and M7
• Replace the varistor(s)
