d1d Digital input set as oA1 or Co1 activation delay (0 – 255 s.), This delay it is considered
when i1F or i2F or i3F or i4F or i5F or i6F or i7F is set as oA1 or Co1
d2d Digital input set as oA2 or Co2 activation delay (0 - 255 s), This delay it is considered
when i1F or i2F or i3F or i4F or i5F or i6F or i7F is set as oA2 or Co2
d3d Digital input set as oA3 or Co3 activation delay (0 - 255 s), This delay it is considered
when i1F or i2F or i3F or i4F or i5F or i6F or i7F is set as oA3 or Co3
d4d Digital input set as oA4 or Co4 activation delay (0 - 255 s), This delay it is considered
when i1F or i2F or i3F or i4F or i5F or i6F or i7F is set as oA4 or Co4
d5d Digital input set as oA5 or Co6 activation delay (0 - 255 s), This delay it is considered
when i1F or i2F or i3F or i4F or i5F or i6F or i7F is set as oA5 or Co6
did Liquid level alarm, signaling delay: (enabled only if one digital input is set as LL)
0 – 255 min
didA External alarm, signaling delay: (enabled only if one digital input is set as EAL)
0 - 255 min
ALMr Manual reset of alarms for compressors and fans.
no = automatic recover of alarm: regulation restart when the correspondent digital input
is disabled; yES = manual recover for the alarms of compressors and fans See also

17.4 Display and Measurement unit
The measurement unit of the parameters referred to temperature or pressure depends on the
parameters dEU, CF and PMu.
NOTE: The controller automatically converts values of set points and parameters referred to the
pressure/temperature when the dEU parameter is changed. In any case check the value
of the parameters referred to temperature and pressure after changing dEU.
dEU Selection of the kind of measurement unit: pressure or temperature
dEU = tMP: the parameters referred to pressure/temperature will be expressed in
temperature according to the value of the CF parameter (°C or °F)
dEU = PrS: the parameters referred to pressure/temperature will be expressed in
pressure according to the value of the PMU parameter (bar, PSI or kPA)
CF Measurement unit for temperature: it is used only with dEU = tMP, and it set the
measurement unit for parameters referred to temperature/pressure.
°C = Celsius degree
°F = Fahrenheit degree
