03:10 Temperature differential
for the start of speed con-
trol 10 K
04:4 Controller amplification of
the speed control 4 %/K
05:10 Minimum solar circuit
pump speed 10 % of

solar circuit pump 75 % of
the maximum possible
speed
07:0 Solar circuit pump inter-
val function OFF
08:60 Set DHW temperature
(maximum cylinder tem-
perature) 60 °C

perature (to protect sys-
tem components) 130 °C
0A:5 Temperature differential
for stagnation time reduc-
tion 5 K

Possible change
03:5 Temperature differential
to adjustable from 5 to 20 K
03:20
04:1 Controller amplification ad-
to justable from 1 to 10 %/K
04:10
05:2 Min. speed of the solar cir-
to cuit pump is adjustable
05:100 from 2 to 100 %
06:1 Maximum speed of the so-
to lar circuit pump is adjusta-
06:100 ble from 1 to 100 %
07:1 Solar circuit pump interval
function ON
The solar circuit pump
starts for short cycles to
capture the collector tem-
perature more accurately.

0A:40
0b:1 Frost protection function
for solar circuit switched on
(not required with
Viessmann heat transfer
medium).
