Possible change
07:0
Interval function of solar circuit
pump switched off
07:1
Interval function of solar circuit pump
switched on
To capture the collector temperature
more accurately, the solar circuit
pump periodically starts for a short
duration.
08:60
The solar circuit pump is stopped if
the actual cylinder temperature
reaches 60 °C (maximum cylinder
temperature).
08:10
to
08:90
The maximum cylinder temperature
is adjustable from 10 to 90 °C.
09:130
The solar circuit pump is stopped if
the collector temperature reaches
130 °C (maximum collector tem-
perature to protect the system
components)
09:20
to
09:200
The temperature is adjustable from
20 to 200 °C.
0A:5
To protect the system components
and heat transfer medium, the
speed of the solar circuit pump is
reduced if the differential between
the actual cylinder temperature
and the set cylinder temperature is
less than 5 K.
0A:0
to
0A:40
The differential between the set cyl-
inder temperature and the start point
for reducing the stagnation time is
adjustable from 0 to 40 K.
0B:0
Collector frost protection function
switched off
0B:1
Collector frost protection function
switched on (not required with
Viessmann heat transfer medium).
0C:1
Delta T monitoring switched on
No flow rate detected in the collec-
tor circuit or flow rate too low.
0C:0
Delta T monitoring switched off
0D:1
Night-time DHW circulation moni-
toring switched on
Unintentional flow rate in the col-
lector circuit is captured (e.g. at
night).
0D:0
Night-time DHW circulation monitor-
ing switched off
0E:1
Calculation of solar yield with
Viessmann heat transfer medium
0E:2
Calculation of solar yield with water
as heat transfer medium (do not se-
lect as operation is only possible
with Viessmann heat transfer medi-
um)
0E:0
Calculation of solar yield switched
off
0F:70
The flow rate in the collector circuit
at the maximum pump speed is set
to 7 l/min.
0F:1
to
0F:255
Flow rate in the collector circuit ad-
justable from 0.1 to 25.5 l/min
10:0
Target temperature control switch-
ed off (see coding address 11)
10:1
Target temperature control switched
on
