Code displayed Causes Consequences Troubleshooting
Error 03
Water temperature
sensor defective or
out of range
Not possible to read
the water
temperature: no
heating.
Check the connection (A1 mark) of the water
temperature sensor (thermowell). Check the
sensor resistance (see table below).
If necessary, replace the sensor.
Error 07
No water in the tank
or open ACI link
No heating
Fill the tank with water.
Check the wiring connection (AC mark), the
conductivity of the water.
Error 09
Water temperature
too high (T>80°C)
Risk of triggering
mechanical safety:
no heating
Check if the actual water temperature at the
water outlet is high (T>80°C).
Check the connection (A1 mark) and the
position of the water temperature sensor
(thermowell), it must be on the stopper.
Check that the electrical backup is not running
continuously. Reset the mechanical safety if
necessary.
Water too cold
Water temperature
too cold (T<5°C)
HP stopped.
Heating in ELEC.
Automatic reset when T>10° C. Check the
conformity of the installation (frost-free room).
Error 21
Air inlet sensor
defective or out of
range (-20 to 60°C)
HP stopped.

Check the connections (A4 mark) and the
positioning of the incoming air sensor. Check
the sensor resistance (see table below). If
necessary, replace the sensor wiring bundle.
Error 22.1
Top evaporator
sensor defective or
out of range (-20 to
110)
HP stopped.
Heating in ELEC.
Check the connections (A4 mark) and the
correct positioning of the sensor on its tube.
Check the fan's operation ensuring that it turns
freely and without stopping (mark M1) and the
power supply on the terminal block
Check the sensor resistance (see table below).
Error 22.2
Bottom evaporator
sensor defective or
out of range (-20 to
110)
HP stopped.
Heating in ELEC.
Check the connections (A4 mark) and the
correct positioning of the sensor on its tube.
Check the fan's operation ensuring that it turns
freely and without stopping (mark M1) and the
power supply on the terminal block
Check the sensor resistance (see table below).
Troubleshooting operations must be carried out exclusively by a professional.
