* the maximum set pressure depends from the connected pressure sensor full scale
P1 is the MAIN operating pressure; the DGBOX control will drive the connected pumps to
keep the system at the selected pressure.
The required pressure must be set in agreement with pump performance.
In the case of operation without flow sensor
(see parameter 3.13 - FLOW SENSOR
), together
with the operating pressure P1, the parameter OFF FREQ SP1 will also have to be set; this
sets the off frequency
(see parameter 2.18 – OFF FREQ SP1).

* the maximum set pressure depends from the connected pressure sensor full scale
P2 is the second work pressure. Operation with the second work pressure is started by the external
control connected to the digital input IN1 or IN2 (see
parameters 3.5/3.6
).
The required pressure must be set in accord with the pump performance.
In the case of operation without flow sensor
(see parameter 3.13 - FLOW SENSOR
), together with
the second work pressure P2, the parameter OFF FREQ SP2 must also be set. This sets the stop
frequency
(see parameter 2.19 – OFF FREQ SP2).
