Dhw; Additional Heat Generator - Viessmann Vitoligno 300-C Installation And Service Instructions For Contractors

Codes
Code 1
(cont.)

DHW

Coding
Coding in the delivered condition
DHW differential
0C:0 The differential temperature of
DHW heating (difference between
system temperature and DHW
temperature) is determined auto-
matically.
DHW return temperature
0D:10 Flow control active. Set return tem-
perature corresponds to DHW tem-
perature plus 10 °C

Additional heat generator

Available if code "Additional boiler: Yes", Hardware
group is selected.
Coding
Coding in the delivered condition
Buffer charging until sensor
D0:1 The additional heat source charg-
es the heating water buffer cylinder
up to the first buffer temperature
sensor.
Buffer charging until temperature
D1:75 The additional heat source charg-
es the heating water buffer cylinder
until the temperature of 75 °C at
the selected sensor (code
"D0:1-5") is reached.

Possible change
0C:0 Fixed setting of differential tempera-
to ture from 1 °C to 20 °C
0C:20
0D:0 Flow control deactivated. Valve is al-
ways fully opened.
0D:1 Flow control active. Set return tem-
to perature corresponds to DHW tem-
0D:30 perature plus value set in °C.
Possible change
D0:0 The heating water buffer cylinder
temperatures are ignored.
D0:2 The additional heat source charges
the heating water buffer cylinder up
to the second buffer temperature
sensor.
D0:3 The additional heat source charges
the heating water buffer cylinder up
to the third buffer temperature sen-
sor.
D0:4 The additional heat source charges
the heating water buffer cylinder up
to the fourth buffer temperature
sensor.
D0:5 The additional heat source charges
the heating water buffer cylinder up
to the fifth buffer temperature sen-
sor.
D1:50 Adjustable value in °C
to
D1:100
