The time programmes for hot water or for a dhw
circulation pump are set in the same way as
described for heating circuit 1. For hot water
and the dhw circulation pump, it is not
necessary to programme comfort temperatures.
4.7.2 Programming holiday periods
For a longer period of time when you are not at home,
you can define a lower room temperature. This will save
heating energy.
The control ensures that the boiler heats up the living
rooms only to this room temperature.
You can, e.g. set a room temperature of 15 °C if you are
on holiday from the 10th to the 24th February. In this
time period, the living rooms are heated only to 15 °C.
You can also select the frost protection function instead
of a room temperature.
Proceed as follows to programme a holiday period:
⇒
Turn the left-hand dial until you reach screen 7
"Holiday programming for cpl. system".
