Possible change
07:0
Interval function of the
solar circuit pump
switched off
07:1
Interval function of the
solar circuit pump switched
on.
To capture the collector
temperature more accu-
rately, the solar circuit
pump starts for short
cycles.
08:60
The solar circuit pump will
stop when the actual cyl-
inder temperature rea-
ches 60 °C (maximum
cylinder temperature).
08:10
to
08:90
The maximum cylinder
temperature can be adjus-
ted from 10 to 90 °C
09:130
The solar circuit pump will
be switched off when the
collector temperature
reaches 130 °C.
09:20
to
09:200
The temperature can be
adjusted 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 when
the differential between
the actual cylinder tem-
perature and set cylinder
temperature is less than
5 K.
0A:0
to
0A:40
The differential between
the set cylinder tempera-
ture and the start point for
reducing the stagnation
time can be adjusted 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 captured in
the collector circuit, or
flow rate too low.
0C:0
Delta T monitoring
switched off.
0d:1
Night circulation monitor-
ing switched on.
Unintentional flow rate is
captured in the collector
circuit (e.g. at night).
0d:0
Night circulation monitor-
ing switched OFF.
