Product information

Vitodens 200-W, WB2C
Set up for operation with natural gas H.
For conversion to LPG P (without conversion kit), see the service instructions.
The Vitodens 200-W should generally only be delivered to those countries specified
on the type plate. For deliveries to alternative countries, an approved contractor must
on his own initiative arrange individual approval in accordance with the law of the
land.
All Vitodens 200-W WB2C up to 35kW have a built-in sealed system kit, circulating
pump and a diverter valve.
The system boilers have two pairs of heating flow / return pipes - the outer pair are
for central heating and the inner for the cylinder primaries. The hot water cylinder is
recommended to be controlled by a Viessmann cylinder temperature sensor, and if
it is an un-vented Vitocell cylinder, a 2-port valve and cylinder control stat is not
required.
The boiler is either supplied with a constant temperature controller (Vitotronic 100)
or a weather-compensated controller (Vitotronic 200).
The Vitotronic 100 (HO2A) provides a 7-day electronic timing for hot water and central
heating. A separate room thermostat may be fitted.
The Vitotronic 200 is a weather compensated controller and includes a 7-day timing
function, outdoor sensor as well as the option to control three separate heating circuits
with independent time and weather-compensated control. Additional remote control-
lers are available. A standard room thermostat can not be connected.
