case an alarm condition occurs, the display will show one of the following messages:
ALARM CODE POSSIBLE CAUSE OPERATION TO BE CARRIED OUT
E0 Functional anomaly of the ambient probe

Check ambient probe state.

If problem persists, replace the
probe.
E1 Functional anomaly of the humidity probe

Check state and connection of
humidity probe.

If problem persists, replace the
probe.
E2
Functional anomaly of the defrosting probe
(In this case, any defrosting will have d5 duration)

Check defrosting probe state.

If problem persists, replace the
probe.
E3
Eeprom alarm
An error has been detected in the EEPROM
memory. (All outputs are deactivated except the
alarm outputs)

Switch the equipment off and on

Minimum or maximum temperature alarm.
A temperature higher or lower to that set for
minimum or maximum temperature alarm has been
reached in the ambient (
See variables At1 and At2,


Check the compressor state.

The probe incorrectly detects the
temperature or the stop/start
control of the compressor does
not work.
Ed Limit Timeout for dehumidification

