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
•
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
•
scroll inside the parameter menu using
To display/set the values of the parameter displayed, press
confirm the changes (returning to the parameter menu).
To save all the new values and exit the parameter menu, press
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).
