Coding addresses overview
Coding in the delivered condition
Interval function for capturing the collector temperature
07:0 Interval function of the solar circuit
pump switched off.
Maximum cylinder temperature (set cylinder temperature)
08:60 Set DHW temperature (maximum
cylinder temperature) 60 °C.
Maximum collector temperature to protect system components
09:130 Maximum collector temperature (to
protect system components)
130 °C.
Stagnation time reduction (speed reduction, solar circuit pump)
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.
Frost protection function, solar circuit
0b:0 Frost protection function for solar
circuit switched off
Flow rate monitoring
0C:1 Flow rate monitoring active.
No flow rate captured in the solar
circuit, or flow rate too low.
Night DHW circulation monitoring
0d:1 Night DHW circulation monitoring
active.
Situations with unwanted flow in
the solar circuit (e.g. at night) are
captured and relayed to the heat
source control unit.
Calculation of solar yield (heat statement)
0E:1 Calculation of solar yield with
Viessmann heat transfer medium.
Flow rate solar circuit
0F:70 The flow rate of the solar circuit at
the maximum pump speed is set to
7 l/min.
Target temperature control
10:0 Target temperature control inac-
tive.

Interval function of the solar circuit
pump switched on.
To capture the collector temperature
more accurately, the solar circuit
pump periodically starts for a short
while.
Set DHW temperature adjustable
from 10 to 90 C.
°
Maximum collector temperature ad-
justable from 20 to 200 C.
°
Stagnation time reduction is disa-
bled.
Temperature differential adjustable
from 1 to 40 K.
Frost protection function for solar cir-
cuit switched on (not required with
Viessmann heat transfer medium).
Flow rate monitoring inactive.
Night DHW circulation monitoring in-
active.
Calculation of solar yield with water
as heat transfer medium (do not set,
as operation is possible only with
Viessmann heat transfer medium).
Calculation of solar yield switched
off.
Flow rate of the solar circuit adjusta-
ble from 0.1 to 25.5 l/min.
Target temperature control active
(see coding address 11).
