Vitodens 100-W B1HE/B1KE Operating

Terminology

Standby mode
Boiler is switched off. Only frost protection of boiler and
DHW tank is active. No central heating, no DHW heating
System version
The system version describes the components of your
system.
Some examples:
Boiler
Heating circuit pump
Mixing valve
Valves
Electronics module
Radiator
Every system is individually configured and adapted to
the local conditions by your heating contractor.
Operating program
The operating program enables you to define the
following, for example:
How you heat your rooms
Whether you heat DHW
Operating status
See "Time program".
Operating mode
See "Heating operation".
Infloor heating
Infloor heating systems are slow, low temperature
heating systems that respond only very slowly to short
term temperature changes.
Heating with reduced room temperature at night therefore
does not result in any significant energy savings.
Heating operation
Operating modes
To heat your home, the boiler provides heat as specified
by the set supply temperature. The operating mode
determines whether the supply temperature is specified
with a fixed value or whether it is automatically
calculated and adjusted subject to several ancillary
conditions.
Your contractor can configure the following operating
modes during commissioning:
Weather-compensated operation
Constant operation
Constant operation
In constant operation the boiler provides heating water
with a constant supply temperature regardless of the
outside temperature.
Weather-compensated heating operation
In weather-compensated operation, the supply
temperature is controlled subject to outside temperature.
More heat is made available at lower outside temperatures
than at a higher ones.
The outside temperature is captured and transmitted to
the control unit by a sensor fitted outside the building.
