i1F
Digital input configuration (18-20)
(dor; dEF)
dor
= door switch function;
dEF
= activation of a
defrost cycle
i2P
Second digital input polarity (18-19)
(oP; CL)
oP
= the digital input is activated by opening the
contact;
CL
= the digital input is activated by closing the contact
i2F
Second digital input configuration
(18-19)
(EAL; bAL; PAL; dor; dEF; ES; AUS; Htr; FAn; HdF; onF)
EAL
= external alarm: “
EA
” message is displayed;
bAL
=
serious alarm “
CA
” message is displayed;
PAL
= pressure
switch alarm, “
CA
” message is displayed;
dor
= door switch
function;
dEF
= activation of a defrost cycle;
ES
= energy
saving;
AUS
= auxiliary relay activation with
oA2=AUS
;
Htr
=
type of inverting action (cooling or heating);
FAn
= fan;
onF
=
to switch the controller OFF
did
Digital input alarm delay (18-20)
when i2F=EAL or i2F=bAL
(0 to 255 min) Delay between the detection of the external alarm
condition and its signaling.
When
i2F= PAL
, it is the interval of time to calculate the
number of pressure switch activation
doA
Door open signaling delay
(0 to 255 min)
nPS
Number of pressure switch activation
(0 to 15) Number of activation, during the
did
interval, before
signaling an alarm event (
i2F=PAL
).
If the
nPS
activation during
did
time is reached, switch OFF and
ON the instrument to restart normal regulation.
odc
Fan/compressor status when door
open
(no; FAn; CPr;F_C;) -
no
= normal;
FAn
= fan OFF;
CPr
=
compressor OFF,
F_C
= fan and compressor OFF
rrd
Outputs restart after doA alarm
(n; Y)
n
= outputs not affected by the
doA
alarm;
Y
= outputs
restart with the
doA
alarm
HES
Delta temperature during an Energy
Saving cycle
(-30.0 to 30.0°C; -54 to 54°F)
Sets the increasing value of the setpoint
[SET+HES]
during the
Energy Saving cycle.
OTHER
Adr
Serial address
(1 to 247) Identifies the instrument address when connected to a
MODBUS compatible monitoring system.
PbC
Type of probe
(ntC, CtC) It allows to set the kind of probe used by the
instrument:
ntC
= NTC-EU probe,
CtC
= NTC-US probe. Set
this
PbC
parameter to
CtC
to support standard CPC temp
sensors - factory default.
onF
ON/OFF key enabling
(nU; oFF; ES)
nU
= disabled;
oFF
= enabled;
ES
= not set it
dP1
Thermostat probe display
dP2
Evaporator probe display
dP3
Third probe display (optional)
dP4
Fourth probe display
rSE
Real setpoint
Shows the setpoint used during the energy saving cycle or
during the continuous cycle.
rEL
Software release for internal use
