Coding level 2
"Heating circuit 1", "Heating circuit 2", "Heating circuit 3" group
Coding in the delivered condition
A6:36 Extended economy mode disa-
bled
A7:0 Only for heating circuits with mixer:
Without mixer economy function
A9:7 With pump idle time (heating circuit
pump "OFF", see function descrip-
tion, page 78)
Note
The max. idle period is 10 h.
b0:0 With remote control:
Heating mode/reduced mode:
Weather-compensated (change
code only for heating circuits with
mixer)
b2:8 With remote control and for the
heating circuit, operation with room
temperature hook-up must be pro-
grammed:
Room influence factor 8 (change
code only for heating circuits with
mixer)
b5:0 With remote control:
No room temperature-dependent
heating circuit pump logic function
(change code only for heating cir-
cuits with mixer)

Possible change
A6:5 Extended economy mode enabled,
to i.e. at a variably adjustable value be-
A6:35 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.
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 12 min.
Heating circuit pump "ON":
If the mixer changes to control
■
function.
If there is a risk of frost

A9:0 Without pump idle time
A9:1 With pump idle time, adjustable from
to 1 to 15:
A9:15 1 = short idle time

Reduced mode: With room tempera-
ture hook-up
