A6:36
Extended economy mode
not
ac-
tive
A6:5
to
A6:35
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 stop
and the mixer closes. The basis for
this is the adjusted outside tempera-
ture. The adjusted outside tempera-
ture is based on the actual outside
temperature and a time constant,
which takes into account the cooling
down of an average building.
A7:0
Only for heating circuit with mixer:
Without mixer economy function
A7:1
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
A8:1
Heating circuit with mixer creates a
demand for internal circulation
pump
A8:0
Heating circuit with mixer creates no
demand for internal circulation pump
A9:7
With pump idle time: Heating cir-
cuit pump "OFF" if set value is
modified by changing the operating
mode or changing the set room
temperature
A9:0
Without pump idle time
A9:1
to
A9:15
With pump idle time, adjustable from
1 to 15.
1 = short idle time
15 = long idle time
b0:0
Only for heating circuit with mixer
and remote control:
Heating mode/reduced mode:
Weather-compensated
b0:1
Heating mode: Weather-compensa-
ted
Reduced mode: With room tempera-
ture hook-up
b0:2
Heating mode: With room tempera-
ture hook-up
Reduced mode: Weather-compen-
sated
b0:3
Heating mode/reduced mode: With
room temperature hook-up
b2:8
Only for heating circuit with mixer
and remote control, and operation
with room temperature hook-up
must be programmed for the heat-
ing circuit:
Room influence factor 8
b2:0
Without room influence
b2:1
to
b2:64
Room influence factor adjustable
from 1 to 64. The higher the value,
the greater the room influence.
b5:0
Only for heating circuit with mixer
and remote control:
Without room temperature-de-
pendent heating circuit pump logic
function
b5:1
to
b5:8
Heating circuit pump logic function,
see the following table.
