This parameter shows the actual motor rotational speed.
This parameter shows the Control Board software version.
Description
This parameter sets the Control Mode (default value: HCS)
ACT: Actuator mode.
A single pump maintains a fixed speed at any flow rate. ACT will
always try to minimize the difference between the speed setpoint and
the actual rotational speed of the motor.
If a 0-10V signal is supplied to terminals 7 and 8, the pump
automatically switches to ACT mode, following the external signal, as
shown in figure 17.
If the external signal is missing, the pump remains in ACT mode, using
the value set as setpoint using the display.
HCS: Hydrovar® Controller mode for Single pump.
The pump maintains a constant pressure at any flow rate: the
Hydrovar® algorithm, based on the set of parameters from P26 to P37
(see Par. 6.5.3), is implemented.
HCS mode must be set in conjunction with the use of an absolute
reading pressure sensor installed in the hydraulic circuit, which
