Viessmann VITOTROL 100-E - Heating Circuit; Night Setback

Screed drying affects all heating circuits:
■
All rooms are heated according to the temperature/
time profile.
Your settings for central heating have no effect on
the duration of screed drying (max. 32 days).
■
DHW heating is enabled.
Underfloor heating system
Underfloor heating systems are slow low temperature
heating systems and respond only very slowly to short
term temperature changes.
Heating with reduced room temperature at night there-
fore does not result in any significant energy savings.
Heating mode
Standard heating mode or comfort heating mode
For periods when you will be at home during the day,
heat your rooms to the standard room temperature or
comfort room temperature.
Reduced heating mode
For periods when you will be absent or during the
night, heat your rooms to the reduced room tempera-
ture. With underfloor heating systems, reduced heating
mode only yields limited energy savings (see "Under-
floor heating system").
Weather-compensated heating mode
In weather-compensated mode, the flow temperature
is controlled according to the outside temperature.
More heat is made available at a lower outside temper-
ature than at a higher one.
The outside temperature is captured and transmitted to
the control unit by a sensor. The sensor is fitted to the
exterior of the building.
Heating circuit
A heating circuit is a sealed unvented circuit connect-
ing the heat generator and the radiators, in which the
heating water circulates.
There may be several heating circuits combined in one
system. For example, one heating circuit for the rooms
occupied by you and one heating circuit for the rooms
of a separate apartment.
Night setback
See "Reduced heating mode"
Room heating
Room heating is carried out with different temperature
levels (see "Heating mode").
The changeover between the temperature levels for
room heating is set via a time program (see "Time pro-
gram").
