(cont.)
Extended economy mode enabled,
i.e. at a variably adjustable value be-
tween 5 and 35 °C plus 1 °C, the
burner and heating circuit pump will
stop and the mixer will close. The
basis for this is the adjusted outside
temperature. The adjusted outside
temperature is based on the actual
outside temperature and a time con-
stant, which takes the cooling down
of an average building into consider-
ation.
With mixer economy function (exten-
ded heating circuit pump logic):
Heating circuit pump also "OFF":
If the mixer has been trying to
■
close for longer than 20 min.
Heating circuit pump "ON":
If the mixer changes to control
■
function.
If there is a risk of frost
■
Without pump idle time
With pump idle time, adjustable from
1 to 15:
1 = short idle time
15 = long idle time
Heating mode: Weather-compensa-
ted
Reduced mode: With room tempera-
ture hook-up
Heating mode: With room tempera-
ture hook-up
Reduced mode: Weather-compen-
sated
Heating mode/reduced mode: With
room temperature hook-up
