Setting
Description
Inverse
Reduced speed with falling actual value signal.
P325 FRQ.LIFT
G
This parameter (default value 30.0 Hz, possible setting 0.0-70.0 Hz) sets the frequency
limit for the required lift value where the required pressure starts to be increased.

Right fct.
The correct frequency is when the pump reaches the set pressure at zero flow. This can be
determined by using P305 JOG.
P330 LIFT AMOUNT
G
This parameter (default value 0.0 %, possible setting 0.0-200.0%) sets the lift amount for
the required lift value in HVAC systems or for compensation of friction losses in long pipe
work.
P330 LIFT AMOUNT

It determines the increase of the set value until the maximum speed (and maximum
volume) is reached.
For an application example, see Example P330 LIFT AMOUNT.
8.3.8 M400 SENSOR
MENU SCOPE
In this submenu it is possible to configure all actual-value sensors that are connected to
the HYDROVAR. However, the following limitations apply:
• It is possible to have maximum two transducers with current output or voltage-signal
output.
• The transducer types: it is not possible to install two different transducer types because
the main configuration is the same for all connected sensors.
This submenu includes the following software parameters:
• Dimension unit
• Configuration
• Type of sensor
• Sensor range
• Sensor curve
• Calibration
P405 DIMENSION UNIT
Selects the unit of measure for the system.
