Instructions for installation and use
11. ADJUSTMENT AND COMMISSIONING
General information
PLEASE NOTE! Some models may have a slightly di erent appear-
ance, but the control function is in principle the same as described
below.
Commissioning
Commission the substation in accordance with the instructions
on pages 3-12.
Filling the system / operating pressure
Fill the unit with water according to the instructions on page 9.
If the pressure drops below 1 bar, water must be added to the sys-
tem.
The operating pressure should never exceed 1.5 bar.
(The safety valve opens at 2,5 bar)
If system pressure drops dramatically within a short time, heating
system should be examined for leakage, - this includes checking
the factory set pressure of the expansion vessel, which is normally
0,5 bar.
Di erential pressure controller (VXi Solo HWP)
The self-acting di erential pressure controller with ow limitation
primarily reduces the high unctuations in pressure in the district
heating network, ensuring constant operating pressure across the
substation and thereby ensures the best possible operating condi-
tions for radiator thermostats, which enables individual control of
the room temperature. The controller closes on rising di erential
pressure or when set max. ow is exceeded.
Control valve closes on rising di erential pressure and opens on fall-
ing di erential pressure to maintain constant di erential pressure.
The di erential pressure is preset from factory and should not be
adjusted afterwards
The controller has a control valve with adjustable ow restrictor,
and the ow setting is being done by the adjustment of the ow
restrictor position. The adjustment can be performed on the basis
of ow adjustment diagram (see relevant instructions).
The controller is equipped with excess pressure safety valve, which
protects control diaphragm from too high di erential pressure.
See enclosed instruction manual,

Di erential pressure controller (Akva Lux II VXi and VXi Solo H)
For Akva Lux II VXi and VXi Solo H, the di erential pressure controller
is installed in the AVQM self-acting ow controller with integrated
control valve. Please see page 18.

Adjustment of the ow volume
Flow setting is being done by the adjustment of
the ow restrictor position.
