A6:5 to
A6:35
Extended economy function enabled: The burner and
heating circuit pump will stop at a variable value, ad-
justable between 5 and 35 °C plus 1 °C. The mixer
closes.
The basis for this is the adjusted outside temperature.
This is based on the actual outside temperature and a
time constant, which takes into account the cooling
down of an average building.
