Code 2
Solar
(cont.)
Coding in the delivered condition
0d:1 Night circulation monitor-
ing switched on.
Unintentional flow rate is
captured in the collector
circuit (e.g. at night).
0E:1 Calculation of solar yield
with Viessmann heat
transfer medium
0F:70 The flow rate in the col-
lector circuit at the maxi-
mum pump speed is set
to 7 l/min.
10:0 Target temperature con-
trol switched off (see cod-
ing address 11)
11:50 Set cylinder temperature
for solar 50 °C.
■ Target temperature
control switched on
(code 10:1):
Temperature at which
the solar heated water
in the DHW cylinder is
to be stratified.
■ Extended control func-
tions set to heat two
DHW cylinders (code
20:8):
If the actual tempera-
ture of a DHW cylinder
reaches the selected
set cylinder tempera-
ture, heating is trans-
ferred to the second
DHW cylinder.
