3. press SET to access the menu; in this way the code appears of the first parameter of the menu selected;
4. press UP and DOWN to display the desired parameter;
5. press SET to display the parameter value;
6. press UP and DOWN to set the desired value;
7. press SET to confirm the value and return to the parameters list; or press ON/OFF to confirm the value and return to menu
list;
8. to pass to the parameters list to the menu list press ON/OFF;
9. to exit the change parameters procedure press ON/OFF again.
If you don't press one of the keys for more than 15 seconds, the possible value display is stored in the relative parameter and you
are forced to exit the change parameters procedure.
5.1.4 Machine Status Display
To display the machine status follow the procedure below:
1. press and release SET: the display shows "SEt" or "AAL" if there are any alarms present;
2. press UP or DOWN until the required parameter is displayed. The parameters can be:
AAL alarms in progress (if any)
SEt setpoint
Pb1 cell temperature probe value
Pb2 evaporator temperature probe value
Pb3 probe 3 value (if present)
Out outlet relays status
InP digital inlets status
3. press SET to display the value;
4. in the case of input or output alarms, press UP and DOWN to scroll the respective alarms present.
5. press SET or ON/OFF (or wait for the 5 seconds timeout) to return to the list of status;
6. press ON/OFF (or wait for the 5 seconds timeout) to return to the normal view.

List of -CPr compressor parameters
Ont 1 Compressor ON time in the
event of probe failure
In the event of an adjustment probe
error, the compressor is enabled in
cyclical mode with set operation and
off times. In particular:
Ont=0: the compressor remains off
Ont>0 and OFt=0: the compressor
remains on
0 … 60 min 15 15 15
OFt 1 Compressor OFF time in the
event of probe failure
0 … 60 min 15 15 15
dOn 1 Compressor activation delay
The time, starting from the switch on request, after which the
compressor is effectively activated.
In the event of network control in sequential mode, this represents the
activation delay from compressor to compressor
0 … 250 sec 0 0 0
dOF 1 Minimum compressor OFF time
The time, starting from the moment of deactivation, for which it is not
possible to restart the compressor
0 … 60 min 3 3 3
dbi 1 Delay between switch on times
The time, starting from the moment of previous activation, for which
the compressor cannot be restarted.
0 … 60 min 0 0 0
OdO 1 Outputs delay at power-on (compressor, fans, defrosting)
This is used to delay the enabling of adjustments after the instrument
has been switched on for a set amount of time.
The transition from stand-by to machine activated (ON command
from the keyboard) bypasses this delay
0 … 60 min 3 3 3
