Setting the parameters
Room Temperature Controller KNX eTR 101-BA2
• Version: 20.04.2021 • Technical changes and errors excepted.
The
minimum and maximum readings
can be saved and sent to the bus. Use the
‘Reset temperature min/max. value’ object to reset the values to the current readings.
The values are not retained after a reset.

Temperature PI controller
Activate the control if you would like to use it.
General rules
Decide in which cases
nominal values and delay times
received per object are to be
kept. The parameter is only taken into consideration if the setting by object is activated
further down. Please note that the setting "After power restoration and programming"
should not be used for the initial start-up, as the factory settings are always used until
the first call (setting via objects is ignored).
Comfort, standby, eco and building protection modes may be used as necessary to
control room temperature.
Comfort
when present,
Standby
when absent,
Eco
as a night-time mode and
Frost / heat protection
(building protection) e.g. when the window is open.
The settings for the temperature control include the set point temperatures for the in-
dividual modes. Objects are used to determine which mode is to be selected. A change
of modes may be triggered manually or automatically (e.g. through a timer, window
contact).
