Description
P35
Smin time [0-100]
G
s
This parameter sets the time delay before a shut-off
below P27 occurs.
It is only used by the Hydrovar
®
controller if P34 = STP.
It affects the control of the pump for HCS, MSE and MSY
control modes.
Default: 0 s.
P36
Window [0-100]
G
%
This parameter sets the ramp control interval, as a
percentage of the pressure setpoint.
It is used to define the range of pressures, around the
setpoint, in which the Hydrovar
®
controller uses slow
acceleration and deceleration ramps instead of fast
ones.
It affects the control of the pump for HCS, MSE and MSY
control modes (also see Par. 6.6.2).
Default: 10%.
P37
Hysteresis [0-100]
G
%
This parameter sets the slow ramp hysteresis, as a
percentage of P36.
It helps define the pressure range, around the setpoint,
in which Hydrovar
®
goes from slow acceleration ramp
(P28) to slow deceleration ramp (P29).
The parameter affects the control of the pump for HCS,
MSE and MSY control modes (also see Par. 6.6.2).
Default: 80%.
P38
Speed Lift [0-MAX*]
G
rpmx10
This parameter sets the speed limit after which the
linear increase of the actual require value starts (P02),
until the total increase (P39) at maximum speed (P26).
Default: P27.
P39
Lift Amount [0-200]
G
%
This parameter sets the increase value of the actual
required value (P02) at the maximum speed (P26),
measured as a percentage of the required value (P01).
It determines the increase of the required pressure set,
useful to compensate for flow resistances at high flow
rates.
Default: 0.

Unit of measurement
Description
P41
Pressure Sensor Unit Of
Measure [BAR, PSI]
G
This parameter sets the unit
of measure (BAr, PSI) for
the pressure sensor.
It affect the head view LED
parameter (see Par. 6.3.4).
Default: bar.
P42
Full scale value for pressure
Sensor 1 4-20mA
[0.0-25.0BAR] /
[0.0-363PSI]
G
bar/psi
This parameter sets the Full
Scale value of the 4-20mA
pressure sensor connected
to analog input 17 and 18.
Default: depending on the
type of pump.
