DIAGNOSTIC
In case of anomalies, the
VISION100 THR
controller warns the operator using alarm codes
shown by the display and an acoustic signal emitted by a buzzer inside the Operational console. In
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
again.
E4 Software compatibility error

Check correct combination
between MASTER board and
Console board.
E6
Discharged battery alarm

Replace the Console lithium
battery (CR2032 type).
Ec
Main alarm (e.g. Thermal protection or max.
pressure switch)
(All outputs are deactivated except the alarm output.
if present)

Check compressor absorption.

If problem persists, contact the
after-sales technical assistance
service.
En
No connection between Console and MASTER
board
.

Check connection between the
two units.

If problem persists, contact the
after-sales technical assistance
service.
Eu
Minimum or maximum humidity alarm.
A humidity higher or lower to that set for minimum or
maximum humidity alarm has been reached in the
ambient (
See variables AU1 and AU2, user
programming level )

Check humidity management.

The probe does not correctly
detect the humidity.
Et
+
Temperature
on display is
flashing
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,
user programming level )

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

Check humidity management.

The probe does not correctly
detect the humidity.
