Solar/group "4"
(cont.)
Coding in the delivered condition
04:4 Controller amplification of speed
control 4 %/K
05:10 Min. speed of the solar circuit
pump 10 % of max. speed
06:75 Max. speed of the solar circuit
pump 75 % of max. possible speed
07:0 Interval function of solar circuit
pump switched off
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 5 K
Reduction in the speed of the solar
circuit pump to protect system
components and heat transfer me-
dium.
0b:0 Frost protection function for solar
circuit switched off
0C:1 Delta-T monitoring ON
No flow rate captured in the solar
circuit, or flow rate too low.
0d:1 Night-time DHW circulation moni-
toring switched on.
Unintentional flow in the solar cir-
cuit is captured (e.g. at night).
0E:1 Heat statement in conjunction with
Viessmann heat transfer medium.
0F:70 Solar circuit flow rate at maximum
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

Possible change
04:1 Controller amplification adjustable
to from 1 to 10 %/K
04:10
05:2 Min. speed of solar circuit pump is
to adjustable from 2 to 100 %
05:100

09:20 Temperature adjustable from 20 to
to 200 °C
09:200
0A:0 Stagnation time reduction not active
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 switched off.
0d:0 Night-time DHW circulation monitor-
ing OFF
0E:2 Never adjust
0E:0 No heat statement
0F:1 Flow rate adjustable from 0.1 to
to 25.5 l/min
