Room Temperature Controller KNX eTR 101-BA2
• Version: 20.04.2021 • Technical changes and errors excepted.
Actual value and set point/base shift displays the actual value in normal functioning
conditions. If the + or - buttons are touched, the set point or the base set point shift are
displayed. The set point/base shift view closes after 7 seconds of inactivity, after which
the display switches back to the actual value.
If a switching object is used, define the behaviour and the value after reset.
The
grades
for the set point changes are predefined.
The control can be switched to comfort mode from eco mode, also night-time opera-
tion, via the comfort extension. This allows the user to maintain the nominal comfort
set point for a longer time, e.g. when having guests. The duration of this comfort ex-
tension period is set here. After the comfort extension period is terminated, the system
returns to eco mode.
Set point for comfort
Comfort mode is usually used for day-time operation when people are present. A start-
ing value is defined for the comfort set point as well as a temperature range in which
the nominal value may be modified.
If set point values are entered separately:
If the comfort set point value is used as a basis:
If the comfort set point value is used as a basis, an increase/decrease relative to this
value is set.
