Changing The Boiler Water Temperature - Viessmann Vitotronic 100, GC1 Operating Instructions And User's Information Manual

Changing the boiler water temperature

Selecting the time programs
In a multi-boiler system with the Vitocontrol-S, VD2/CT3/CM2, the boiler water
temperature is determined by the Vitocontrol-S, VD2/CT3/CM2 for all boiler
control units.
It is not possible to make the setting on the Vitotronic 100, GC1.
You can select time programs for central heating, domestic hot water (if a DHW
tank is installed) and the DHW re-circulation pump (if installed). The DHW
re-circulation pump ensures that hot water is available at the taps when required.
A time program consists of 4 time phases, i.e.
The central heating can be switched up to 4 times per day to and fro between
the "normal room temperature" and the "reduced room temperature".
The domestic hot water supply and DHW re-circulation pump can be switched
on and off up to 4 times per day.
Time phase 1 is preset in the factory for all days of the week, i.e. during this
time central heating takes place with the normal room temperature, domestic
hot water heating takes place and the DHW re-circulation pump is switched on.
The following buttons are assigned to the time programs:

You can set identical time programs for all days of the week or individual time
programs for each day of the week.
When setting the time programs, please take into account the reaction time of
the heating system. Therefore choose correspondingly earlier starting and
finishing times.
