• Version: 10.09.2018 • Technical changes and errors excepted.
The
increment
for the setpoint changes is predefined. Whether the change only re-
mains temporarily active (not saved) or is also retained after power supply restoration
(and programming), is specified in the first section of "General control". This also ap-
plies to a comfort extension.
The control may be reset to comfort mode from eco mode, which is used as night mo-
de, via the comfort extension. This allows the user to maintain the comfort setpoint
value for a longer time, e.g. when having guests. The duration of this comfort extensi-
on period is set. After the comfort extension period expires, the system returns to eco
mode.
Comfort Setpoint
Comfort mode is usually used for daytime mode when people are present. A starting
value is defined for the comfort setpoint as well as a temperature range in which the
setpoint value may be modified.
If setpoint values are entered separately:
If the comfort setpoint value is used as a basis:
If the comfort setpoint value is used as a basis, the reduction/increment of the value is
set.
If the comfort setpoint is used as the basis without a switching object, a dead zone is
specified for the control mode "heating
and
cooling" to avoid direct switching from he-
ating to cooling.
