Introductory Information; Product Information - Viessmann VITODENS 200-W Operating Instructions For The System User

Intended use
(cont.)
Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibi-
ted and will result in an exclusion of liability. Incorrect
usage also occurs if the components in the heating
system are modified from their intended use (e.g. if the
flue gas and ventilation air paths are sealed).

Product information

The control unit is a boiler and heating circuit control
unit for the following operating modes:
Weather-compensated operation
■
■ Continuous operation
■ Room temperature-dependent operation
Your heating contractor will configure the operating
mode during commissioning in accordance with your
heating system. These instructions describe all 3 oper-
ating modes.
Weather-compensated operation
Fig. 1
In weather-compensated operation, the flow tempera-
ture level is controlled according to the outside temper-
ature. The lower the outside temperature, the higher
the flow temperature. This means that more heat is
provided for central heating on cold days than on
warmer days.
In weather-compensated operation, 1 heating circuit
without mixer and up to 2 heating circuits with mixer
can be operated with the control unit.
Continuous operation
Fig. 2
In continuous operation the heat generator provides
heating water with a constant flow temperature regard-
less of the outside temperature.
In continuous operation, 1 heating circuit without mixer
and up to 2 heating circuits with mixer can be operated
with the control unit.
Room temperature-dependent operation
Fig. 3
In room temperature-dependent operation, the central
heating is switched on or off subject to the room tem-
perature. The flow temperature remains constant.
In room temperature-dependent operation, 1 heating
circuit without mixer can be operated with the control
unit.
