Measurement unit and regulation type
dEU: Default measurement unit for displaying
bar=Bar; °C=°C)
The dEU parameter sets the measurement unit also for these parameters: Pbd, LSE,
HSE, LAL, HAL. After modifying this parameter check the set point and the
parameters Pbd, LSE, HSE, LAL, HAL.
Pbd: Proportional band or neutral zone width (0.10÷5.00 bar).
Set the dEU par. and the target set point before setting this parameter. The band (or
zone) is symmetrical compared to the target set point, with extremes: set+Pbd/2 ... set-
Pbd/2. The measurement unit depends on the dEU par.
onon:
Minimum time between 2 following switching ON of the same compressor
(0÷255 min).
oFon:
Minimum time between the switching off of a compressor and the following
switching on. (0÷255min).
Note: usually onon is greater than oFon.
Cdn: don and doF equal for all the compressors.
YES: don and doF equal for all the compressors:
no: don and doF different for each compressor. In this case there are as don1, don2...
and doF1, doF2... as the compressors are.
don1:
Time delay between the insertion of the first compressor and the following one.
(It is present only if Cdn=no) (0÷255 sec)
….
don6:
Time delay between the insertion of the sixth compressor and the following
one. (It is present only if Cdn=no) (0÷255 sec)
doF1:
Time delay between the switching off of the first compressor and the following
one. (It is present only if Cdn=no) (0÷255 sec)
……
doF6:
Time delay between the switching off of the sixth compressor and the following
one. (It is present only if Cdn=no) (0÷255 sec)
don: Time delay between the insertion of two different compressors. (It is present only if
Cdn=yES) (0÷255 sec)
doF: Time delay between switching off of two different compressors. (It is present only if
Cdn=yES (0÷255 sec)
donF:
Minimum time a stage stays switched ON (0÷255 s)
FdLy: “don” delay enabled also for the first call. If enabled the triggering of the step is
delayed for a “don” value, respect to the call. (no = “don” not enabled; yES=”don”
enabled)
