Possible causes
ST4 sensor temperature too low Wait until the exterior temperature
ST3 sensor temperature over
60°C or evaporator scaled up
Cabling not respected on the
appliance's supply terminals,
Electricity provider has changed
the order of the phases
Temporary disconnection of the
power supply to one or more
phases
Pressure fault in the low
pressure circuit (if problem
persists after resetting)
Water condenser scaled up
Insufficient water flow
Air and water emulsion passed
into the device
Flow controller blocked
Compressor discharge
temperature too high
Sensor is faulty or offline
(J12-A1 connector)
Sensor is faulty or offline (J8-A1
connector)
Sensor is faulty or offline
(terminals 1-2 connector J3-A2)
Sensor is faulty or offline
(terminals 3-4 connector J3-A2)
Solutions
rises
Clean the evaporator, if problem
persists, call an approved technician
Invert phases on power terminals
(appliance switched off )
Contact the electricity provided to
find out if your installation has been
modified.
Call an approved technician
Clean the water condenser
Increase flow using by-pass, check
that the pool filter is not clogged
Check the pool's hydraulic circuit
Check the flow controller
Call an approved technician
