Fixed settings
• Minimum compressor ON time is 1 minute;
• If there is no defrost relay, the compressor will be shut down for defrost;
• Freeze the display when defrost, it returns when the temperature reaches the set point;
• Alarm is bypassed 1 hour after defrost;
• Open door alarm will be activated after detecting the door opening 5 minutes.
Setting the set point (desired temperature)
• press for 1 s, the set value will start flashing after a few moments;
• increase or decrease the value using or ;
• press to confirm the new value.
Switching the device ON/OFF
press for more than 3 s. The control and defrost algorithms are now disabled and the instru-
ment displays the message“OFF” alternating with the temperature read by the set probe.
Manual defrost (only for models C/Y)
press down for DOWN more than 3 s (the defrost starts only the temperature conditions are
valid).
Show defrost probe temperture(only for models C/Y)
press and together.
Access and setting type F (frequent) and type C (configuration)
parameters
• press for 3 s (the display will show “PS”);
• to access the type F and C parameter menu, enter the password “22” using / ;
• to access the F parameter menu only, press (without entering the password);
• scroll inside the parameter menu using / .
To display/set the values of the parameter displayed, press , then / and finally to
confirm the changes (returning to the parameter menu).
To save all the new values and exit the parameter menu, press for 3 s;
To exit the menu without saving the changed values (exit by timeout) do not press any button for
at least 60 s.
Display and functions
