7.2 Setting the minimum operating pressure for
Magcontrol
The "p " minimum operating pressure is determined by the location of the
0
Servitec.

The calculation of the minimum operating pressure can be directly calculated
and saved during initial commissioning using the Reflex Control Smart app for
configuration. Please always check the correct inlet pressure of the expansion
vessel in the system. Proceed as follows:
1 In the app, set the controller to "Magcontrol".
2. Determine the "P0" minimum operating pressure of the device relative to
the "p0" initial pressure of the expansion vessel.

The device is installed at the same level as the expansion vessel
(∆h

Note!
The safety valve actuating pressure must always be observed for the
target value of the Servitec

Note!
Avoid dropping below the minimum operating pressure. Vacuum,
vaporisation and the formation of vapour bubbles are thus excluded.
