PAR
DESCRIPTION
Type of defrosting
0 = electric
d1 d1
1 = by hot gas
2 = via stopping of compressor
Temperature at the and of defrosting (only if P3=1)
d2 d2
(see also d3)
if P3 = 0 o 2 → defrosting duration
d3 d3
if P3 = 1 → maximum defrosting duration (see also d2)
0 = defrosting will be not activated
Defrosting when instrum. is switched on (only if d8=0, 1 or 2)
d4 d4
Delay in activation of defrosting after instrument is switched on (only if
d5 d5
d4=1) (see also i5)
(3)
Temperature displayed during defrosting
d6 d6
1 = if the cell temperature < Setpoint + r0, at most working Setpoint + r0
if the cell temperatura > Setpoint + r0, at most the cell temperature
when defrosting is activated
d7 d7
Dripping duration
Defrosting activation methods:
0 = AT INTERVALS
when instrument has been running for d0
1 = AT INTERVALS
d8 d8
when compressor has been switched on for d0
2 = AT INTERVALS
when evaporator temp. has been < d9 temp. for d0 time
3 = IN REAL TIME
activated at the times established in parameters Hd1...Hd6
Evaporator temperature is higher than that at which the defrost interval
d9 d9
counter is suspended (only if d8=2)
Minum time that the compressor must be switched on before defrosting
dA dA
can be activated (only if d1=1)
temperature alarms
Temperature associated with the minimum temp. alarm (AL code)
A0 A0
0 = cell temperature
Minimim temperature alarm (AL code)
A1 A1
(see also A0, A2 and Ab)
Type of minimum temperature alarm (AL code)
A2 A2
1 = relative to working Setpoint (Setpoint A1)
2 = absolute (A1)
Maximum temperature alarm (AH code)
A4 A4
(see also A5 and Ab)
Type of maximum temperature alarm (AH code)
0 = alarm absent
A5 A5
1 = relative to working Setpoint (Setpoint A4)
2 = absolute (A4)
Delay in maximum temperature alarm (AH code) after the instrument is
A6 A6
switched on
(3)
A7 A7
Temperature alarm delay (AL-AH codes)
Delay in maximum temperature alarm (AH code) following the conclusion
A8 A8
of evaporator fan
(13)
Delay in maximum temperature alarm (AH code) following the disactiva-
A9 A9
tion of the door microswitch
Durat. of interruption in the power supply when instr. is switch on Alarm
AA
AA
stored when the power supply is restored (PF code)
Ab Ab
Differential of parameters A1, A4 and F1
evaporator fan
Evaporator fan activity during normal operation
1 = switched on
2 = in parallel with the compressor
F0 F0
3 = dependent on F1
(16)
4 = switched off if the compressor is switched OFF, dependent on F1 if the
compressor is switched ON
5 = dependent on F6
Evaporator temperature above the limit at which the evaporator fan is
F1 F1
switched off (only if F0=3 or 4) (see also Ab)
