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

Code 2
DHW/group "3"
(cont.)
Coding in the delivered condition
65:0 Do not adjust
67:40 For solar DHW heating: set DHW
temperature 40 °C. Reheating is
suppressed above the selected set
temperature: boiler only starts as
backup if the rise in the DHW tem-
perature is too low.
6F:... Max. heating output for DHW heat-
ing in %, specified by the coding
card
71:0 DHW circulation pump: "ON" ac-
cording to time program (only for
weather-compensated control
units)
72:0 DHW circulation pump: "ON" ac-
cording to time program (only for
weather-compensated control
units)
73:0 DHW circulation pump: "ON" ac-
cording to time program (only for
weather-compensated control
units)

Solar/group "4"

Select "Solar" for weather-compensated control unit
(see page 58).
Select "4" for constant temperature control unit (see
page 58).

73:1 "ON" from once per hour for 5 min
to up to 6 times per hour for 5 min dur-
73:6 ing the time program
73:7 Constantly "ON"
Note
The solar group is only displayed if a solar control
module, type SM1, is connected.
