Setting the time program for central heating/central cooling
Factory setting: one time phase from 00:00 to 24:00 h
for every day of the week with the "Standard" operat-
ing status.
Note
■
The factory setting is suitable for operation with
underfloor heating systems.

When making settings, please bear in mind that your
heating system requires some time to heat or cool
the rooms to the required temperature.
Operating status for central heating/central cooling
"Standard"
■
Central heating/central cooling takes place with the
standard room temperature "Set room tempera-
ture": see page 26.
"Reduced"
■
Central heating takes place with the reduced room
temperature "Set red. room temp": see page 26.
Note
In the "Reduced" operating status, a heating/cooling
circuit is not cooled.
"Fixd value"
■
Central heating takes place with the max. permissi-
ble flow temperature of the respective heating circuit,
irrespective of the outside temperature.
■
Central cooling takes place with the min. flow tem-
perature of the respective heating circuit, irrespective
of the outside temperature.
■
Factory settings: your contractor may have adjusted
these values.
–
