day of the week.
• dd1 = Sunday defrost

• dd6 = Friday defrost
• dd7 = Sunday defrost
Ld1…Ld6
Defrost starting time: (00h00min to 23h50min) these parameters set the
beginning of the programmable defrost cycles during any ddx day. Example: when
Ld2=12.4, the second defrost starts at 12:40 am during working days.
N.B.: To disable a defrost cycle set it to “nu”(not used). Ex: if Ld6=nu; the sixth defrost cycle will
be disabled.

16 DIGITAL INPUT
The free voltage digital inputs are programmable in different configurations by the i1F or i2F
parameters.
16.1 DOOR SWITCH INPUT (dor)
It signals the door status and the corresponding relay output status through the odC parameter: no =
normal (any change); FAn = Fan OFF; CPr = Compressor OFF; F_C = Compressor and fan OFF.
Since the door is opened, after the delay time set through parameter did, the door alarm is enabled, the
display shows the message “dA” and the regulation restarts is rtr = yES. The alarm stops as soon as
the external digital input is disabled again. With the door open, the high and low temperature alarms are
disabled.
16.2 GENERIC ALARM (EAL)
As soon as the digital input is activated the unit will wait for did time delay before signalling the “EAL”
alarm message. The outputs status doesn’t change. The alarm stops just after the digital input is de-
activated.
16.3 SERIOUS ALARM MODE (bAL)
When the digital input is activated, the unit will wait for did delay before signalling the “CA” alarm
message. The relay outputs are switched OFF. The alarm will stop as soon as the digital input is de-
activated.
16.4 PRESSURE SWITCH (PAL)
If during the interval time set by did parameter, the pressure switch has reached the number of activation
of the nPS parameter, the “CA” pressure alarm message will be displayed. The compressor and the
regulation are stopped. When the digital input is ON the compressor is always OFF. If the nPS
activation in the did time is reached, switch off and on the instrument to restart normal
regulation.
16.5 AUXILIARY OUTPUT CONTROL (AUS)
To activate and deactivate the auxiliary output
