∙ Verify if an error message
is displayed on the
keypad. If so, refer to the
corresponding section.
∙ If no message is displayed,
try increasing the water
temperature by setting
the set point value 2°C
above the actual water
temperature. Press on
the Up key to increase
temperature.
∙ Verify if the water heater
indicator lights up.
The water heater indicator
is lit up when the water
heater is active. It flashes
when an increase in
temperature has been
demanded but the water
heater has not yet started.
THE SPA IS NOT HEATING
in.xe - 240 V water heater
(5,5kW, 4 kW or 2 kW)
in.xe - 120 V water heater (1
kW)
If the water heater indicator lights up:
∙ Take voltage readings at the heater terminals.
For the in.yj and in.ye, in.yt, you should measure:
240 V : between the line (L1) and neutral (N) for control
systems configured for 240V.
120 V: between the line (L1) and neutral (N) for control
systems configured for 120 V .
For in.xe control systems, you should measure:
240 V : between line 1 (L1) and line 2 (L2)
120 V : between line 1 (L1) and neutral (N)
For North American control systems, if the measured tension is
not correct, verify that the water heater terminals are correctly
plugged in.
If they are correct replace the control system.

For European control systems, if the measured tension is not
correct, replace the water heater fuse.
in.yj - F2 fuse
in.ye and in.yt – F1 fuse
in.xe - F3 fuse
If the tension is correct, ensure that the water heaters power
cables are correctly plugged into the control systems terminal
block. If so, replace the water heater.
If the water heater indicator does not display on the keypad,
measure the water temperature and compare with the
displayed temperature:
∙ If the difference is lower than 2°F (1,1°C),
there is not problem.
∙ If the difference is higher than 2°F (1,1°C),
replace the water heater.
If the problem persists, replace the control system.
