5.2 Test the circulation pump
Optimum (variable speed) circulation pump
If a fixed speed circulation pump is used, may be the case for DHP-AQ Mini, do the test according to the next
chapter: "Constant speed circulation pump"
Optimum (variable speed) circulation pump is factory installed in DHP-AQ Midi and DHP-AQ Maxi. The OPTIMUM option is however not
activated from factory.
The following settings are made in the MANUAL TEST menu. To activate MANUAL TEST, see description above. Use + or – to move up
and down in the menu.
