Adjusting the performance

5.5.1

Performance preselection

The power switch can be used to preselect the perform-
ance in ten levels between 50 % and 100 % of the rated
heating output.
By reducing the performance of the appliance and
adapting it to the level you actually require, you can
reduce the exit temperature and save energy.

5.5.2 Regulation

In the range between the preselected performance and
the minimum possible appliance performance (around
40 %), the quantity of gas is automatically, continuously
adjusted to the water flow volume (in other words, the
actual amount drawn off at the taps), thus keeping the
exit temperature constant.
