Procedure to restore the default parameters:

▪ ensure that no other procedure is in progress

▪ hold down

and

▪ press

within 15 seconds to set "743"

▪ press

or not operate for 15 seconds

▪ hold down

and

▪ press

within 15 seconds to set "149"

▪ press

or not operate for 15 seconds: the display will show "dEF" flashing, than the instrument will exit the procedure

▪ stop the power supply

Make sure that the default value parameters is correct

The unit of measurement depends on P2 parameter

(1)

Properly set the parameters corresponding to the regulators after modifying P2 parameter

(2)

The parameter has effect even after an interruption in the power supply that occurs while the instrument in switched on

(3)

The time established with the parameter is counted even when the instrument is switch off

(4)

If parameter C1 is set to 0, the delay after the end of the cell probe error will be 2 minutes

(5)

The parameter differential is 2,0 °C / 4 °F

(6)

If when the instrument is switched on the condenser temperature is already above that established in C7 parameter, than C8 parameter will not have effect

(7)

The instrument stores the defroster interval count every 30 minutes; the modiﬁ cation of d0 parameter takes effect following the end of the preceeding interval of following the activation

(8)

of manual defrosting

The display returns to normal operation when, at the end of evaporator fan disactivation, the cell temperature falls below that at which the display was initially blocked (or if a tempe-

(9)

rature alarm is signaled)

If P3 parameter is set 0 or 2, the instrument will function as if d8 parameter were set to 0

(10)

If when defrosting is activated, the operating duration of the compressor is less than the time established with parameter dA, the compressor will remain on for the amount of time

(11)

necessary to complete defrosting

If P3 parameter is set to 0, the instrument will function as if A0 parameter were set to 0, but will not store the alarm

(12)

During defrosting and dripping and when the evaporator fan is stopped, the temperature alarms are absent, provided that these where signaled after the activation of defrosting

(13)

During activation of the door microswitch input, the maximum temperature alarm is absent, provided the alarm was signaled after the activation of the input

(14)

When power is restored, the alarm will always be signaled

(15)

If P3 parameter is set to 0, the instrument will function as if F0 parameter were set to 2

(16)

The compressor is switched off 10 seconds after the activation of the input; if the input is activated during defrosting or when the evaporator fan is disactiveted, the activation will not

(17)

have any effect on the compressor

The instrument stores the alarm once the time established in i2 parameter has expired; if i2 parameter is set to -1, the instrument will not store the alarm

(18)

Make sure that the time established with i7 parameter is less than that established with i9 parameter

(19)

To avoid damaging the unit connected to the instrument, change the parameter setting when the instrument is switched off

(20)

If u2 parameter is set to 0, switching off the instrument will cause the cell light or the auxiliary output to switch off (the next time the instrument is switched on the unit connected will

(21)

remain switched off);

If u2 parameter is set to 1, switching off the instrument will not cause the cell light or the auxiliary output to switch off (the next time the instrument is switched on the unit connected

will remain switched on)

If no one relay controll the defrost, it will however occur by stopping of compressor

(22)

for some seconds: the display will show "PA"

for some seconds: the display will show "dEF"
