This is how the heat pump is wired when delivered.
The heat pump is connected to the mains on a single ta-
riff (one consumer meter) (1). The power company re-
serves the right to switch off the compressor and the
auxiliary heating as required by means of a ripple cont-
rol signal. The duration and frequency of the deactivati-
on is determined by, or must be arranged with, the
power company.
