Coding in the delivered condition Possible change
A6:36 Extended economy mode disa-
bled (only for weather-compensa-
ted control units)
A6:5
to
A6:35
Extended economy mode active, i.e.
the burner and heating circuit pump
are switched off at a variable value,
adjustable from 5 to 35 °C plus 1 °C.
Mixer will be closed. The basis for
this is the adjusted outside tempera-
ture. This is derived from the actual
outside temperature and a time con-
stant that takes account of the way
an average building cools down.
A7:0 Without mixer economy function
(only for heating circuit with mixer)
(only for weather-compensated
control units)
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
A9:7 With pump idle time: Heating cir-
cuit pump "OFF" if the set value is
altered through a change in oper-
ating mode or through a change in
the set room temperature (only for
weather-compensated control
units)
A9:0 Without pump idle time
A9:1
to
A9:15
With pump idle time, adjustable from
1 to 15
B0:0 With remote control: Heating
mode/reduced mode: Weather-
compensated (only change the
code for the heating circuit with
mixer) (only for weather-compen-
sated control units)
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 With remote control and for the
heating circuit, operation with room
temperature hook-up must be pro-
grammed: Room influence factor 8
(only change the code for the heat-
ing circuit with mixer) (only for
weather-compensated control
units)
B2:0 Without room influence
B2:1
to
B2:64
Room influence factor adjustable
from 1 to 64
B5:0 With remote control: No room tem-
perature-dependent heating circuit
pump logic function (only change
the code for the heating circuit with
mixer) (only for weather-compen-
sated control units)
