Malfunction
The device is not • No display
operational • The pool temperature is above the set-
point temperature
• A message is displayed on the screen
• Absent or inadequate water flow-rate
• The parameter «on/off ctrl» is on «yes»
• The air temperature is too low
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
blocked in the open position
• 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 from
but the compressor time to time
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 inappropriate
circuit breaker • The cable cross-section is too small
• The supply voltage is too low
• Voltage drops when the compressor is
powered on
• Varistor(s) VA1 and/or VA2 is/are out of
order

5.3 FAQ

Is it possible to In order to
improve temperature improve the
performance? efficiency of
your heat
pump it is
recommended
that you:
Check that
filtration time
is sufficient
Setting the set-point to maximum will not heat the water any faster.
H0439100.C - EN - 2015-01
Cause
Sensor out-of-order or
disconnected (terminals
3-4 of connector J3 white
on plate A2)
Sensor out-of-order or
disconnected
(connector J7 black on
plate A1)
• Incorrect connection
between plates A1 and
A2
• Card supply defect
• Cards out of order
Possible causes
• Protect the pool with a cover (floating cover, roller cover, etc.), to avoid
heat loss
• Choose periods when the outside temperature is warm (on average
> 10°C) in order to facilitate the temperature increase (this may take
several days. The actual time will vary according to weather conditions
and the power of the heat pump)
• Keep the evaporator clean
• During the heating phase, water flow must be continuous (24/24)
• To maintain the temperature throughout the season, allow for
"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)
Solution
Replace or reconnect the
sensor
Replace or reconnect the
sensor
• Check connections
(connectors J8 and J9 yellow,
and J7 and J4-J5 black)
• If the defect persists, contact
an approved technician
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»)
• Wait until the air temperature returns to within
the operating range
• 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)
