Coding in the delivered condition
01:4 Stop temperature differential for
solar circuit pump 4 K
02:0 Solar circuit pump is not speed-
controlled
03:10 Temperature differential for the
start of speed control 10 K
04:4 Controller amplification of the
speed control 4 %/K
05:10 Min. speed of the solar circuit
pump 10 % of the max. speed.
06:75 Maximum speed of the solar circuit
pump 75 % of maximum possible
speed
07:0 Interval function of the 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
0b:0 Frost protection function for solar
circuit switched off
0C:1 Delta T monitoring enabled
No flow rate captured in the solar
circuit, or flow rate too low.
0d:1 Night-time DHW circulation moni-
toring enabled
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
0 A: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
