Extended economy mode active:
The burner and heating circuit pump
are switched off and the mixer will
be closed at a variable value, adjust-
able between 5 and 35 °C plus 1 °C.
The basis for this is the adjusted
outside temperature. This is derived
from the actual outside temperature
and a time constant that takes ac-
count of the way an average building
cools down.
With mixer economy function (exten-
ded heating circuit pump logic):
Heating circuit pump also "OFF":
If the mixer has been trying to
■
close for more than 20 min.
Heating circuit pump "ON":
If the mixer changes to control
