(1) the unit of measure depends on parameter P2
(2) set the parameters related to the regulators appropriately after the modification of the parameter P2
(3) if parameter C1 has value 0, the delay since the end of the cabinet probe error will however be 2 min
(4) the differential of the parameter is 2.0 °C/4 °F
(6) the instrument stores the count of the defrost interval every 30 min; the modification of parameter d0 has effect since the end of the previousdefrost interval or since
the activation of a defrost by hand
(7) the display restores the normal operation as soon as the after dripping evaporator fan delay ends and the cabinet temperature falls belowthe one that has locked the
display (or if a temperature alarm arises)
(8) if parameter P3 has value 0 or 2, the instrument will work as if parameter d8 had value 0
(9) if (to the defrost activation) the duration of the activation of the compressor is shorter than the time you have set with parameter dA, thecompressor will further
remain turned on the fraction of time required to complete it
(10) if parameter P3 has value 0, the instrument will work as if parameter A0 had value 0
(12) during the defrost, the dripping and the evaporator fan delay the temperature alarms are not enabled, on condition that they have arisenafter the activation of the
defrost
(14) if parameter P3 has value 0, the instrument will work as if parameter F0 had value 2
Setting the working setpoint
make sure the keyboard is not locked and no procedure is running
press LED
press or
after changing the value, confirm by pressing
You also can modify the working setpoint through parameter SP.

2=the defrost will be activated when the evaporator temperature will have remained below
the tem-perature d9 the time d0 (8)
evaporator temperature above which the count of the defrost interval is suspended (only if
d8 = 2)
minimum time the compressor must be remained turned on (to the defrost activation) in
order that thedefrost can be activated (only if d1 = 1) (9)
TEMPERATURE ALARMS
temperature joined to the lower temperature alarm
0=cabinet temperature
1=evaporator temperature (10)
temperature below which the lower temperature alarm is activated; also look at A0 and A2
(4)
kind of lower temperature alarm
0=alarm not enabled
1=relative to the working setpoint (or "working setpoint - A1"; consider A1 without sign)
2=absolute (or A1)
temperature above which the upper temperature alarm is activated; also look at A3 and
A5 (4)
kind of upper temperature alarm
0=alarm not enabled
1=relative to the working setpoint (or "working setpoint + A4"; consider A4 without sign)
2=absolute (or A4)
upper temperature alarm delay since you turn on the instrument (only if A3 = 0)
temperature alarm delay
upper temperature alarm delay since the end of the after dripping evaporator fan delay
(only if A3 = 0)(12)
EVAPORATOR FAN
evaporator fan activity during the normal operation
0=turned off
1=turned on
2=according to the compressor
3=according to F1 (14)
4=turned off if the compressor is turned off, according to F1 if the compressor is turned on
(14)
evaporator temperature above which the evaporator fan is turned off
(only if F0 = 3 or 4) (4)
evaporator fan activity during the defrost and the dripping
0=turned off
1=turned on
2=according to F0
duration of the after dripping evaporator fan delay
