rS Proportional band offset: PI band offset. It permits to move the proportional band of the
PI. With rS=0 the band is between Set-Pbd/2 ÷ Set+Pbd/2;
inC Integration time: (0 ÷ 999s) PI integration time
2Pbd Proportional band or neutral zone width for circuit 2 (0.1÷5.0bar/0.5÷30°C or
1÷150PSI/1÷50°F) The band (or zone) is symmetrical compared to the target set point,
with extremes: set-Pbd/2 ÷ set+Pbd/2. It is used as proportional band for PI algorithm.
The measurement unit depends on the dEU, CF, PMU par.
2rS Proportional band offset for circuit 2: PI band offset. It permits to move the proportional
band of the PI. With rS=0 the band is between Set-Pbd/2 ÷ Set+Pbd/2;
2inC Integration time for circuit 2: (0 ÷ 999s) PI integration time
ton Inverter at maximum capacity before starting a new load (0÷255s)
toF Inverter at minimum capacity before stopping a load (0÷255s)
ESC Energy saving value for compressors: (-20÷20bar; -50÷50°C) this value is add to the
compressor set point.
2ESC Energy saving value for compressors of second circuit: (-20÷20bar; -50÷50°C) this
value is add to the compressor set point.
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.
don: Time delay between the insertion of two different compressors (0÷99.5min; res.
10s).
doF: Time delay between switching off of two different compressors (0÷99.5 min; res.
10s)
donF: Minimum time a stage stays switched ON (0÷99.5 min; res. 10s)
MAon Maximum time for compressor ON (0 ÷ 24 h; with 0 this function is disabled.) If a
compressor keeps staying on for the MAon time, it’s switched off and it can restart after
the oFon standard time.
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)
FdLF “doF” delay enabled also for the first switching off. It enables the “doF” delay between
the request of a release and the actual switching off. (no = “doF” not enabled;
yES=”doF” enabled)
odo: Regulation delay on start-up: (0÷255s) on switching ON the instrument starts working
after the time delay imposed in this parameter.
LSE: Minimum set point: The measurement unit depends on dEU parameter. It sets the
minimum value that can be used for the set point, to prevent the end user from setting
incorrect values.
HSE: Maximum set point: The measurement unit depends on dEU parameter. It sets the
maximum acceptable value for set point.
2LSE: Minimum set point for circuit 2: The measurement unit depends on dEU parameter. It
sets the minimum value that can be used for the set point, to prevent the end user from
setting incorrect values.
2HSE: Maximum set point for circuit 2: The measurement unit depends on dEU parameter. It
sets the maximum acceptable value for set point.
17.6 Liquid injection thermostat
Lit: Set point ( °C) for cooling injection thermostat (0 ÷ 150°C) The reference probe is set
by LiPr parameter, the thermostat relay is given by the relay set as Lin.
Lid: Differential for cooling injection thermostat (0.1 ÷ 10.0) The reference probe is set by
LiPr parameter
LiPr Probe for cooling injection thermostat:
nP: function disabled
P3: probe P3 (term. 3-4)
P4: probe P4 (term. 33-34)
