Operating modes
The room thermostat function has
four operating modes:
– Frost protection mode:
The room temperature control is out
of service; the room is only heated if
the room temperature has fallen so
low that there is a risk of the heating
installation freezing.
– Comfort mode:
The setpoint for the room
temperature is set to a value which
enables "normal use" of the room at
a pleasant temperature.
– Standby mode:
The room temperature is lowered
(e.g. during temporary absence) so
that heating costs are saved but the
comfort temperature can be
reached again quickly.
– Night mode:
If the room is not used for an
extensive period during the night;

the room temperature is lowered to
a pleasant night temperature and
can be increased again relatively
quickly in the morning.
It is possible to toggle betweent these
operating modes through switching
telegrams to the communication
objects "Frost protection", "Night" and
"Comfort" or via the panel display
(see also the diagram of the
operating modes). The frost/heat
protection has the highest priority i.e.
it is not possible to switch to another
operating mode in this case. To do
so, the frost/heat protection mode
must first be deactivated e.g. by
closing an open window. Comfort
mode has the next highest priority
followed by night mode. If none of the
three operating modes is active, the
room thermostat is in standby mode.
Party time (Comfort extension)
If the panel is switched to night mode
via the bus (or internally), the party
time can be activated via the panel
display (change to comfort mode, see
diagram top left). Once the party time
has elapsed, the thermostat switches
back to night mode.
During the party time, the symbols for
night and party are shown together in
the display. By pressing the party
button again, the party time can be
reset manually to night reduction.
This function can also be used for the
temporary deactivation of the heat and
frost protection. As in night mode, it is
possible to switch to comfort mode
for the parameterised period. The
function is switched on and off in the
same way. The symbols for frost
protection and party are shown
together in the display during this
comfort extension.
