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;
Setting the set point (desired temperature)
• press for 1 s, the set value will start fl ashing after a few moments;
• increase or decrease the value using or ;
• press to confi rm 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 (confi guration)
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 fi nally to
confi rm 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
During normal operation, the controller displays the ambient temperature. In addition, the
display has LEDs that indicate the activation of the control functions (see Table 1), while the
3 buttons can be used to activate/deactivate some of the functions (see Table 2).
