5.3 Adapting settings for heating system
automatic mode
Normally, the time program provides the best heating comfort.
In the default settings for each heating circuit, time program 1
is active with the following settings:
• Starting at 06:00 (08:00 on Saturdays and Sundays) heat
to 21 °C (heating mode). Starting at 23:00 heat to 15 °C
(setback mode).
These settings provide economic heating from 23:00 in the
evening until 06:00 in the morning on the following day.
Heating circuit 1 ... 4 with C 400 or heating circuit 1 ... 8
with C 800
If more than one heating circuit has been installed and
configured, the settings for heating circuits 1 ... 4 or 8 are
changed in the same way as for systems with one heating
circuit. However, changes are valid only for the selected
heating circuit.
A remote control can be installed for each heating circuit. If an
CR100 is assigned to a heating circuit as a remote control, the
CR100 determines the time program for the heating system.
For this heating circuit, the time program cannot be set at the C
400/C 800. The Time program menu is not displayed for the
heating circuit assigned to the remote control. The most recent
change to the operating mode in this heating circuit (on the
CR100 or the C 400/C 800) is always the valid setting.
