Heat pump output data

information regarding the measuring method and inter-
pretation of the heat pump output data provided in these
operating and installation instructions:
The output data provided in the text and diagrams of these
operating and installation instructions has been calculated
according to the standardised measuring conditions of EN 14511.
Please note that these standardised measuring conditions do not
always wholly match the local on-site conditions of the individual
system user. The discrepancy may be significant, depending on
the measuring method selected, i.e. the degree of deviation of
the selected method, from the conditions stipulated in EN 14511.
Further factors that may have an influence on the measured values
are the measuring equipment, the system configuration, the age
of the system and the flow rates.
It is only possible to confirm the output data provided in these
operating and installation instructions for a specific heat pump if
the measurement used for test purposes was taken under identical
conditions and parameters, i.e. in accordance with EN 14511.
