In this menu, you can enter the user code. According to
the entered code, a different access to the setting area
of the controller is possible.
Each digit of the four-digit code must be individually
entered and confirmed.
After confirming, the cursor goes automatically to the next digit.
To receive access to all extended areas of the installation, enter the installation code 9856.
To avoid that settings are incorrectly modified, we recommend entering the customer user
code
after completion of all installation work and before the controller is given to
uninitiated system operators or customers.
15 Advanced settings
15.1 Min speed*
In this menu item you can adapt the minimum speed of the primary pump.
If an additional check valve is integrated, it can be the case that no circulation is available in the
primary circuit at low flow rates. This can be compensated by increasing the minimum speed.
*Settings only visible with installer code (see chapter "User code").
