8 - DIAGNOSTIC
If there is an error it will be shown on the display as in Figure

Some errors can be temporary or permanent. If it’s permanent,
to try to restore operation, the appliance must be turned off
for at least 30 seconds and turned on again.
Error code
Code Description Operation status Possible causes and solutions
00 E1 Outdoor temperature sensor fault
1. Reduced compressor
speed;
2. Switch between cooling
and heating not working;
3. The appliance will use
the compressor discharge
temperature as a reference
for the antifreeze function;
4. No longer calls the auxilia -
ry heater.
Check that the outdoor temperature sensor is not broken,
short-circuited or with a value out of range. Replace it if
necessary.
00 E2 DHW temperature sensor fault (Tw) DHW mode not available
Check that the DHW temperature sensor (Tw) is not
open, short-circuited or with too high drifts. Replace it if
necessary.
00 E3 Heating temperature sensor fault (Th) Heating mode not available
Check that the heating temperature sensor (Th) is not
open, short-circuited or with too high drifts. Replace it if
necessary.
00 E4 Cooling temperature sensor fault (Tc) Cooling mode not available
Check that the cooling temperature sensor (Tc) is not
open, short-circuited or with too high drifts. Replace it if
necessary.
00 E5 Supply temperature sensor fault Appliance stopped
Check that the supply temperature sensor is not open,
short-circuited or with too high drifts. Replace it if neces -
sary.
00 E6 Return temperature sensor fault Appliance stopped
Check that the return temperature sensor is not open,
short-circuited or with too high drifts. Replace it if neces -
sary.
00 E7
Evapo-condensing temperature sensor
fault
Compressor stopped
Check that the temperature sensor is not open, short-
circuited or with too high drifts. Replace it if necessary.
00 E8
Internal battery 1 temperature sensor
fault (N/A)
System 1 stopped (N/A)
00 E9 Room temperature sensor fault (Tr)
1. Operation with non-
selectable room temperature
control.
2. Non-selectable room
temperature compensation
function.
The room sensor (Tr) is inside the electrical connection
box (Figure 5-10).Check that the room temperature sen -
sor (Tr) is not open, short-circuited or with too high drifts.
Replace it if necessary.
00 Ea Internal Eeprom fault The appliance works Replace the water side control board.
