Solar/Group "4 - Viessmann VITODENS 200-W Service Instructions Manual

Solar/Group "4"

Select "Solar" for weather-compensated control units (see page 55).
Select "4" for constant temperature control units (see page 55).
Note
The solar group is only displayed if a solar control module, type SM1, is connected.
Coding
Coding in the delivered condition
00:8 The solar circuit pump
starts when the collector
temperature exceeds the
actual cylinder tempera-
ture by 8 K.
01:4 The solar circuit pump
stops when the differen-
tial between the collector
temperature and the
actual cylinder tempera-
ture is less than 4 K.
02:0 Solar circuit pump is not
speed-controlled
03:10 The temperature differen-
tial between the collector
temperature and actual
cylinder temperature is
regulated to 10 K.
04:5 Controller amplification of
the speed control 5 %/K.
05:10 Minimum speed of the
solar circuit pump 10 % of
the maximum speed
Possible change
00:2 The differential between
to the actual cylinder temper-
00:30 ature and the start point for
the solar circuit pump can
be adjusted from 2 to
30 K.
01:1 The differential between
to the actual cylinder temper-
01:29 ature and the stop point for
the solar circuit pump can
be adjusted from 1 to
29 K.
02:1 Solar circuit pump is
speed-controlled with
wave pack control
02:2 Solar circuit pump is
speed-controlled with
PWM control
03:5 The differential tempera-
to ture control between col-
03:20 lector temperature and
actual cylinder tempera-
ture can be adjusted from 5
to 20 K
04:1 Controller amplification
to adjustable from 1 to
04:10 10 %/K
05:1 Minimum speed of the
to solar circuit pump is adjust-
05:100 able from 1 to 100 %
