Explanations
Extended economy function disabled
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.
Explanations
Heating circuit pump also "OFF":
If the mixer has been trying to close for some time.
■
Heating circuit pump "ON":
If the mixer changes to control function
■
If there is a risk of frost
