Coding in the delivered condition
08:60 Set DHW temperature (maximum
cylinder temperature) 60 °C.
09:130 Maximum collector temperature (to
protect system components)
130 °C.
0A:5 Temperature differential for stagna-
tion time reduction (reduction in
the speed of the solar circuit pump
to protect system components and
heat transfer medium) 5 K.
0b:0 Frost protection function for solar
circuit switched off.
0C:1 Delta T monitoring switched on.
No flow rate captured in the solar
circuit, or flow rate too low.
0d:1 Night circulation monitoring ena-
bled.
Unintentional flow rate is captured
in the solar circuit (e.g. at night).
0E:1 Heat statement in conjunction with
Viessmann heat transfer medium.
0F:70 Solar circuit flow rate at the maxi-
mum pump speed 7 l/min.
10:0 Target temperature control switch-
ed off (see coding address "11").
11:50 Set solar DHW temperature 50 °C.
Target temperature control
■
switched on (code "10:1"):
temperature at which the solar
heated water is to be stratified
into the DHW cylinder.
Code "20:9" (heating of two
■
DHW cylinders) is set:
when one DHW cylinder reaches
its set DHW temperature, the
second DHW cylinder is heated.
12:10 Minimum collector temperature
(minimum start temperature for the
solar circuit pump) 20 °C.
20:0 No extended control function ena-
bled.
Possible change
To capture the collector temperature
more accurately, the solar circuit
pump periodically starts for a short
duration.
08:10 Set DHW temperature adjustable
to from 10 to 90 °C.
08:90
09:20 Temperature adjustable from 20 to
to 200 °C.
09:200
0A:0 Stagnation time reduction is disa-
bled.
0A:1 Temperature differential adjustable
to from 1 to 40 K.
0A:40
0b:1 Frost protection function for solar cir-
cuit switched on (not required with
Viessmann heat transfer medium).
0C:0 Delta T monitoring disabled.
0d:0 Night circulation monitoring switched
off.
0E:2 Do not adjust
0E:0 No heat statement.
0F:1 Flow rate adjustable from 0.1 to
to 25.5 l/min.
0F:255 1 step
10:1 Target temperature control switched
on.
11:10 The set solar DHW temperature is
to adjustable from 10 to 90 °C.
11:90
12:0 No minimum limit enabled.
12:1 Minimum collector temperature ad-
to justable from 1 to 90 °C.
12:90
20:1 Additional function for DHW heating.
20:2 Differential temperature control 2.
20:3 Differential temperature control 2
and auxiliary function.
20:4 Differential temperature control 2 for
central heating backup.
