(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) the value depends on the kind of model (-50 for the models for PTC probe, -40 for the models for NTC probe)
(4) the value depends on parameter r5 (50 if parameter r5 has value 0, 199 if parameter r5 has value 1)
(5) if parameter r5 has value 1 (heating action), the defrost management will not be enabled
(6) the display restores the normal operation as soon as the defrost ends and the cabinet temperature falls below the one that has locked the display (or if a
temperature alarm arises)
(7) during the defrost the temperature alarms are not enabled, on condition that they have arisen after the activation of the defrost
(8) during the activation of the door switch input the upper temperature alarm is not enabled, on condition that it has arisen after the activation of the input
(9) the differential of the parameter is 2.0 °C/4 °F
(10) the compressor is turned off spent 10 s since the activation of the input; if the input is activated during the defrost, the activation will provoke no effect on the
compressor
(11) if parameter i5 has value 2 and parameter i7 has value -1, the instrument will work as if parameter i7 had value 0.
Setting the working setpoint
make sure the keyboard is not locked and no procedure is running

after changing the value, confirm by pressing
You also can modify the working setpoint through parameter SP.

maximum working setpoint
cooling or heating action
0 = cooling (defrost management is enabled)
1 = heating (defrost management is not enabled)
COMPRESSOR PROTECTIONS
compressor delay since you turn on the instrument
minimum time the compressor remains turned off
minimum time the compressor remains turned on
DEFROST
defrost interval; also look at d8 (6)
0=the defrost at intervals will never be activated
defrost duration if P3 = 0 or 2; defrost maximum duration if P3 = 1
0=the defrost will never be activated
defrost when you turn on the instrument (1 = YES)
defrost delay when you turn on the instrument (only if d4 = 1)
temperature shown during the defrost
0=cabinet temperature
1=if to the defrost activation the cabinet temperature is below "working setpoint + r0", at
most "work-ing setpoint + r0"; if to the defrost activation the cabinet temperature is above
"working setpoint +r0", at most the cabinet temperature to the defrost activation (7)
TEMPERATURE ALARMS
temperature below which the lower temperature alarm is activated; also look at A0 and A2
(4)
temperature above which the upper temperature alarm is activated; also look at A3 and
A5 (4)
upper temperature alarm delay since you turn on the instrument (only if A3 = 0)
temperature alarm delay
EVAPORATOR FAN
kind of contact digital input
0 = NO (the input will be active if you close the contact)
1 = NC (the input will be active if you open the contact)
kind of digital input (effect provoked by the activation of the digital input)
0 = no effect
1 = MULTIPURPOSE (activation external alarm) - spent the time i7 the display will show
the code "iA" flashing (as long as the input will be deactivated)
2 = MULTIPURPOSE (activation manostat) - the compressor will be turned off and the
display will show the code "iA" flashing (as long as the input will be deactivated); also look
at i7
3 = DOOR SWITCH INPUT (compressor turned off) - the compressor will be turned off (as
long as the input will be deactivated) and spent the time i7 the display will show the code
"id" flashing (as long as the input will be deactivated) (10)
if i5 = 1, delay to signal the multipurpose input alarm
-1 = no signal
if i5 = 2, compressor delay since the deactivation of the multipurpose input (11)
if i5 = 3, delay to signal the door switch input alarm
-1 = no signal
"POSITIVE TEMPERATURE -2/+8°C" (48b)
