C16: Maximum value of current or voltage inputs
C16 indicates the value measured when the input is given its maximum possible signal, that is 10 V when using 0÷10 V probes, 20 mA
with 0÷20 mA and 4÷20 mA probes.
Access:
Keypad: if C50=1, 3 or 4 Ü + for 5” and password 77;
if C50=0 or 2 Ü the parameter can only be displayed.
Remote control: if C50=4 Ü press “ENABLE” and and
;
Modes: in all modes except C00=0 and 1 (“SLAVE DIRECT” and “SLAVE REVERSE” )
Operating range: from C15 to 100 for temperature probes in °C (C18=0);
from C15 to 212 for temperature probes in °F (C18=1);
from C15 to 100 for humidity probes in rH (C18=2) or pressure probes in bar.
Default: C16 = 100 for FCM00NTC00 and FCM0001000, 30.0 for FCM0002000.
Not Available in FCM00NTC00.
C17: 'Filter' on probe input
C17 measures the effect of the 'filter' on the controlled value. It is the time constant of the filter.
When setting low values there is a low 'filtering' effect, with a quick reading of any variation measured by the sensor.
When setting high values the responses of the sensor are transmitted more slowly; this ensures greater immunity against noises, hence
steadier readings.
Access:
Keypad: if C50=1, 3 or 4 Ü + for 5” and password 77;
if C50=0 or 2 Ü the parameter can only be displayed.
Remote control: if C50=4 Ü press “ENABLE” and and
;
Other parameters: not accessible when using pressure probes with unspecified refrigerant (C13=2, 4, 6 and C14=0).
Operating range: from 0.0 to 10.0 seconds.
Default: C17 = 1.0 s.
C18: Unit of measure
C18 allows you to set the exact unit of measure for each parameter (St1, St2, P01, P02, C07, C15, C16, P40, P41, P25, P26, P27, P34,
P35, P36). The unit of measure will appear in bar only when you use pressure probes with types of refrigerant different from those listed
above (see C14).
Access:
Keypad: if C50=1, 3 or 4 Ü + for 5” and password 77;
if C50=0 or 2 Ü the parameter can only be displayed.
Remote control: if C50=4 Ü press “ENABLE” and and
;
Modes: in all modes except C00=0 and 1 (“SLAVE DIRECT” and “SLAVE REVERSE”)
Other parameters: not accessible when using pressure probes with unspecified refrigerant (C13 and C14).
Operating range: from 0 to 1 for FCM00NTC00
from 0 to 2 for FCM0001000 and FCM0002000.
C18=0 Ü °C (temperature in degrees Celsius)
C18=1 Ü °F (temperature in degrees Fahrenheit)
C18=2 Ü rH (relative humidity)
Default: C18 = 0 (°C).
C19: Second probe
C19 indicates how to use the second probe.
Access:
Keypad: if C50=1, 3 or 4 Ü + for 5” and password 77;
if C50=0 o 2 Ü the parameter can only be displayed.
Remote control: if C50=4 Ü press “ENABLE” and and ;
Modes: all modes except C00=0 and 1 (“SLAVE DIRECT” and “SLAVE REVERSE” )
Operating range: from 0 to 4
C19=0 Ü second probe not used (disconnected input)
C19=1 Ü the actual measure is the greater of the two probes (the lower in the “REVERSE” mode)
C19=2 Ü the actual measure is the lower of the two probes (the greater in the “REVERSE” mode)
C19=3 Ü the actual measure is the difference between probe 1 and probe 2
C19=4 Ü the second probe is used exclusively for defrost control
Default: C19 = 0 Ü second probe not used.
