Probe 4 configuration
P4c Probe 4 setting (22-23):
nP = not used:
nt10 = NTC 10 K 38 - 42
nt86 = NTC 86 K 38 - 42
ntcH = NTC 10 K extended range (150°C)
O4 Probe 4 calibration the range depends on the dEU parameter:
dEU = °C: -12.0 - 12.0;
dEU = °F: -200 - 200;
Probe selection for fan
FPb Probe selection for condenser fan
nP = not used:
P1 = Probe 1
P2 = Probe 2
P3 = Probe 3
17.3 Other input configuration
iF01 Digital input 1 configuration (10 - 13)
nu = Not used: the digital input is disabled.
oA1 = Safety digital input for load 1, term. 15 - 17; (Factory setting);
oA2 = Safety digital input for load 2, term. 16 - 17
oA3 = Safety digital input for load 3, term. 17 - 18
oA4 = Safety digital input for load 4, term. 17 - 20
oA6 = Safety digital input for load 6, term. 21 - 22
inF = Safety digital input of inverter for fan, used when none relay is configured as inverter
for fans
LP1 = Low pressure switch
LP2 = low pressure switch, circuit2
HP = High pressure switch
ES = Energy saving;
oFF = instrument shut down;
LL = liquid level alarm
SIL = to enable the silence function
EAL = generic external alarm, it doesn’t affect the regulation
Co1 = running proof function for load 1, term. 15 - 17
Co2 = running proof function for load 2, term. 16 - 17
Co3 = running proof function for load 3, term. 17 - 18
Co4 = running proof function for load 4, term. 17 - 20
Co6 = running proof function for load 6, term. 21 - 22
NOTE: Also the following values oA5, Co5, are present. These values must not be used.
iF02 Digital input 2 configuration (10 - 14) – For the values see iF01; Factory setting oA2.
iF03 Digital input 3 configuration (10 - 11) – For the value see iF01; Factory setting oA3.
iF04 Digital input 4 configuration (10 - 12) – For the value see iF01; Factory setting oA4.
iF05 Digital input 5 configuration (9 - 10) – For the value see iF01; Factory setting LP1.
iF06 Digital input 6 configuration (25 - 26) – For the value see iF01; Factory setting HP.
iF07 Digital input 7 configuration (27 - 28) – For the value see iF01; Factory setting LL.
NOTE: Digital input 7 is enabled only when P4C = NP, otherwise it operates as
temprature probe
iP01 Digital input 1 polarity (10 - 13):
oP: the digital input is activated by opening the contact.
CL: the digital input is activated by closing the contact.
