Automatically the parameter list of the “Hot Key” is downloaded into the Controller memory, the
“doL” message is blinking followed a by flashing “End”.
4.
After 10 seconds the instrument will restart working with the new parameters.
5.
Remove the “Hot Key”..
NOTE the message “Err” is displayed for failed programming. In this case turn the unit off and then on if
you want to restart the download again or remove the “Hot key” to abort the operation.

ALARM SIGNALLING
Message Cause
Outputs
“P1” Thermostat probe failure
Compressor and heating outputs off
“P2” Evaporator probe failure
Defrost and by time
“P3”
Humidity probe failure
Humidity regulation off
“HA”
High temperature alarm
Outputs unchanged
“LA”
Low temperature alarm
Outputs unchanged
“HHA” High humidity alarm
Outputs unchanged
“HLA” Low humidity alarm
Outputs unchanged
“dA”
Door switch alarm
Outputs depending on the odC parameter
“EAL” External alarm
Other outputs unchanged
“BAL” Serious external alarm
Outputs OFF
“PAL” Pressure
switch alarm
Outputs OFF
The alarm message is displayed until the alarm condition recoveries.
All the alarm messages are showed alternating with the room temperature except for the “P1” which is
flashing. To reset the “EE” alarm and restart the normal functioning press any key, the “rSt” message is
displayed for about 3s.
12.1
SILENCING BUZZER
Once the alarm signal is detected the buzzer, if present, can be silenced by pressing any key.
12.2
ALARM RECOVERY
Probe alarms : “P1” (probe1 faulty), “P2”, “P3”; they automatically stop 10s after the probe restarts
normal operation. Check connections before replacing the probe.
Temperature alarms “HA” and “LA” automatically stop as soon as the thermostat temperature returns
to normal values or when the defrost starts.
Humidity alarms “HHA” and “LHA” automatically stop as soon as the humidity returns to normal
values.
Door switch alarm “dA” stop as soon as the door is closed.
External alarms “EAL”, “BAL” stop as soon as the external digital input is disabled
Pressure switch alarm “PAL” alarm is recovered by switching OFF the instrument.
