Coding in the delivered condition
02:... Data dependent on the software
version of solar control module
SM1
03:10 The temperature differential be-
tween the collector temperature
and actual DHW temperature is
regulated to 10 K.
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 The solar circuit pump is switched
off when the actual DHW tempera-
ture reaches the maximum cylinder
temperature (60 °C).
09:130 The solar circuit pump is switched
off if the collector temperature rea-
ches 130 °C (maximum collector
temperature to protect the system
components).
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-time DHW circulation moni-
toring switched on
Unintentional flow rate in the solar
circuit (e.g. at night) is captured.
0E:1 Heat statement in conjunction with
Viessmann heat transfer medium
0F:70 Solar circuit flow rate at maximum
pump speed 7 l/min
40
Possible change
02:0 Solar circuit pump not speed-con-
trolled
02:1 With wave packet control function
Never adjust
02:2 Solar circuit pump speed-controlled
with PWM control
03:5 Temperature differential adjustable
to from 5 to 20 K
03:20
04:1 Controller amplification adjustable
to from 1 to 10 %/K
04:10
05:2 Min. speed of solar circuit pump ad-
to justable from 2 to 100 %.
05:100
06:1 Max. speed of solar circuit pump ad-
to justable from 1 to 100 %.
06:100
07:1 Interval function of solar circuit pump
switched on
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 switched off
0d:0 Night-time DHW circulation monitor-
ing switched off
0E:2 Never adjust
0E:0 No heat statement
0F:1 Flow rate adjustable from 0.1 to
to 25.5 l/min.
