It allows to activate a defrost cycle when the device is turned on.

 

The selection of the after-reset defrost option has priority over the compressor regulation and over the continuous 

cycle activation.

 

d5:  DEFROST DELAY AFTER RESET OR EXTERNAL TRIGGER

 

It defines the time interval between the reset and the beginning of a defrost.

 

In case a digital trigger is used to start defrost, it defines the delay between the activation of defrost and its effective 

start.

 

d6:  DISPLAY LOCK DURING DEFROST

 

It allows to lock the display to the last value measured before defrost start.

 

The display comes back to normal operation when the temperature reaches for the first time its set-point or when 

the d8 alarm exclusion time finishes.

 

If the display is not locked, during defrost the device displays the message dF.

 

dd:  DRIPPING TIME

 

Compressor and fan are OFF for this time after a defrost cycle finishes.

 

If dd is not zero, the defrost stops when the device has turned the compressor OFF (in case of a hot gas defrost) 

and the reverse cycle relay is turned OFF.  If dd=0 the dripping phase is not initiated: after defrost only the reverse 

cycle relay is deactivated.

 

d8:  ALARMS EXCLUSION TIME AFTER DEFROST AND DOOR OPEN

 

After defrost the temperature alarm is inhibited for the time defined by this parameter.  This allows the temperature 

to exit the alarm range during and after defrost.

 

It also defines the time to inhibit the temperature alarm after door is closed if the door switch is active.

 

d9:  FORCE DEFROST START

 

It allows to ignore the protection times for the compressor (minimum ON, minimum OFF, interval between two 

ONs) when the defrost is started.

 

d   : DEFROST PROBE MEASURE

 

It enables the display of the value measured by the defrost probe when this is connected.

 

dC: TIME BASE

 

It allows to modify the time base used for the defrost interval (dI) and the defrost duration (dP).

 

0=dI in hours, dP in minutes

 

1=dI in minutes, dP in seconds.

ALARMS

 

A0: ALARM AND FAN DELTA

 

It represents the temperature hystheresys of the “regulator” of alarm and of the fan regulator.

 

AL: MINIMUM RELATIVE SET

 

The low temperature alarm is activated when the temperature has values less than the minimum set relatively to 

the set point.

 

If the parameter is 0 the minimum alarm is inhibited.

 

AH: MAXIMUM RELATIVE SET

 

The high temperature alarm is activated when the temperature has values greater than the maximum set relatively 

to the set point.

 

If the parameter is 0 the maximum alarm is inhibited.

 

Ad: TEMPERATURE ALARM DELAY

 

The alarm of high and low temperatures is acknowledged with an Ad delay from the moment the cause starts.  

This delay is active also at the reset of the device.

 

After defrost, door open/closed, continuous cycle, the temperature alarm is immediately acknowledged after the 

delay set by the defrost and the continuous cycle.
