Room temperature control and
limitation
With the room temperature limitation
function, the heating circuit pump can
be disabled if the room temperature
exceeds the current room temperature
setpoint by more than the preset
differential.
The room temperature limitation does
not work in the case of pure weather
compensation.
Boost heating
Boost heating is used to reach the
new setpoint more quickly when
switching from the reduced setpoint
to the comfort setpoint, thus reducing
the heat-up time. During boost
heating, the room temperature
setpoint is raised by the value set
here. A higher setting leads to
shorter heat-up times, a lower setting
to longer heating times.
 Boost heating is possible with or
without room sensor.
Quick setback
During quick setback, the heating circuit
pump is deactivated and, in the case of
mixing valve circuits, the mixing valve is
fully closed.
 Function with room sensor:
When using the room sensor, the
function keeps the heating switched off
until the room temperature has dropped
to the level of the reduced setpoint or
the frost level. When the room
temperature has fallen to the reduced
level or the frost level, the heating
circuit pump will be activated and the
mixing valve will be released.
 Function without room sensor:
Quick setback switches the heating off
for a certain period of time, depending
on the outside temperature and the
building time constant.
 Quick setback is possible with or
without a room sensor.
