CUr; tEn
For models with PWM / O.C. output:
- PM5 = PWM 50Hz;
- PM6 = PWM 60Hz;
- OA7 = two state, it can be used as an open collector output.
For models with [4 to 20mA] or [0 to 10V] output:
- Cur = 4 to 20mA current output;
- tEn = 0 to 10V voltage output.

switched off;
Y = the auxiliary output state is unrelated to the ON/OFF device
status.
DIGITAL INPUTS

d1d
15
Digital input 1 activation delay. 0 to 255min
When
[i1F
=
PAL]
: time interval to calculate the number of the
pressure switch activation.
When [i1F = EAL or bAL] (external alarms): d1d parameter
defines the time delay between the detection and the successive
signaling of the alarm.
When [i1F = dor]: this is the delay to activate door open alarm.
i2P
CL
Digital input 2 polarity. OP; CL
CL
means the digital input is activated by closing the contact;
OP means the digital input is activated by opening the contact.
i2F
LiG
Digital input 2 configuration.

dor; dEF; AUS;
LiG; OnF; Htr;
FHU; ES; HdY
EAL
=
external alarm;
bAL
=
serious external alarm;
PAL = pressure switch activation; dor = door open;
dEF = defrost activation; AUS = auxiliary activation;
LiG = light activation; OnF = switch on/off the instrument;
Htr = change type of action; FHU = not used;
ES = activate energy saving; HdY = activate holiday function.
d2d
5
Digital input 2 activation delay. 0 to 255min
When
[i2F
=
PAL]
: time interval to calculate the number of the
pressure switch activation.
When [i2F = EAL or bAL] (external alarms): d2d parameter
defines the time delay between the detection and the successive
signaling of the alarm.
When [i2F = dor]: this is the delay to activate door open alarm.
i3P
CL
Digital input 3 polarity. OP; CL
CL
means the digital input is activated by closing the contact;
OP means the digital input is activated by opening the contact.
i3F
ES
Digital input 3 configuration.
EAL; bAL; PAL;
dor; dEF; AUS;
LiG; OnF; Htr;
FHU; ES; HdY
EAL
=
external alarm;
bAL
=
serious external alarm;
PAL = pressure switch activation; dor = door open;
dEF = defrost activation; AUS = auxiliary activation;
LiG = light activation; OnF = switch on/off the instrument;
Htr = change type of action; FHU = not used;
ES = activate energy saving; HdY = activate holiday function.
d3d
0
Digital input 3 activation delay. 0 to 255min
When
[i3F
=
PAL]
: time interval to calculate the number of the
pressure switch activation.
When [i3F = EAL or bAL] (external alarms): d3d parameter
defines the time delay between the detection and the successive
signaling of the alarm.
When [i3F = dor]: this is the delay to activate door open alarm.
nPS
15
Number of pressure switch activations
before lock.
0 to 15
Number of activation of the pressure switch, during the
d1d, d2d
and d3d interval, before signaling the alarm event [i1F, i2F or i3F
= PAL]. If the nPS activation in the d1d, d2d or d3d time is
reached, switch off and on the instrument to restart normal
regulation.
OdC
F-C
Compressor and fan status when open
door.
no; FAn; CPr; F-C
no
= normal;
Fan
= Fan OFF;
CPr
= Compressor OFF;
F_C = both Compressor and Fan OFF.
rrd
15
Output restart delay with door open. 0 to 255min
The outputs stopped by the
OdC
parameter can restart after
rrd
time.
ENERGY SAVING
ESP P1
Energy saving probe selection. nP; P1; P2; P3; P4; P6; tEr

HES 0.0
Temperature increasing during Energy
Saving.
[-30.0°C to 30.0°C]
[-54°F to 54°F]
Sets the increasing value of the set point during the Energy Saving
cycle.
PEL nU
Energy saving activation when Light
or/and AUX are switched off.
nU(0); LIG(1); AUS(2); LEA(3)
Energy saving enabled when:
- LiG: light switched off;
- AUS: AUX switched off;
- LEA: both light and AUX switched off.
If nU then not used function.
