10.9 Data table
The output data refers to new appliances with clean heat ex-
changers. The power consumption of the integral auxiliary drives
represents the maximum value and may vary subject to operating
point. The power consumption of the integral auxiliary drives is
included in the output details of the appliance (to EN 14511).
