Solar/Group "4"
(cont.)
Coding in the delivered condition
06:80 Maximum speed of the
solar circuit pump 80 % of
the maximum possible
speed
07:0 Interval function of the
solar circuit pump
switched OFF
08:60 The solar circuit pump will
stop when the actual cyl-
inder temperature rea-
ches 60 °C (maximum
cylinder temperature).
09:130 The solar circuit pump
stops if the collector tem-
perature reaches 130 °C
(maximum collector tem-
perature to protect the
system components).
0A:5 To protect the system
components and heat
transfer medium, the
speed of the solar circuit
pump is reduced when
the differential between
the actual cylinder tem-
perature and set cylinder
temperature is less than
5 K.
0b:0 Collector frost protection
function switched OFF

Possible change
06:1 Maximum speed of the
to solar circuit pump is adjust-
06:100 able from 1 to 100 %
07:1 Interval function of the
solar circuit pump switched
ON.
To capture the collector
temperature more accu-
rately, the solar circuit
pump starts for short
cycles.
08:10 The maximum cylinder
to temperature is adjustable
08:90 from 10 to 90 °C.
09:20 The temperature is adjust-
to able from 20 to 200 °C.
09:200
0A:0 The differential between
to the set cylinder tempera-
0A:40 ture and the start point for
reducing the stagnation
time can be adjusted from
0 to 40 K.
0b:1 Collector frost protection
function switched ON (not
required with Viessmann
heat transfer medium).
