Setting the parameters
Room Temperature Controller KNX eTR 101-BA2
• Version: 20.04.2021 • Technical changes and errors excepted.
The
status object
reports the current status of the output (0% = OFF, >0% = ON) and
may for example be used for visualisation, or to switch off the heating pump as soon
as the heating is switched off.
Then define the
type of control
. Heating and/or cooling may be controlled in two stag-
es.
General set point values
You may enter separate set point values for each mode or use the comfort set point as
a basic value.
If you are using the controls for both heating
and
cooling, you may also select the set-
ting "separately with switching object". Systems used for cooling in the summer and
for heating in the winter can thus be switched from one to the other.
If you are using the basic value, only the deviation from the comfort set point value is
listed for the other modes (e. g., 2°C less for standby mode).
Determine, which
value must be shown on the display.
Actual value only means that the currently measured temperature value (or the mixed
value defined) is displayed. A set point change using buttons is then
not
possible.
Set point/base shift only means that the currently valid set point (e.g. 21.5 °C) or the
base set point shift (e.g. +2 °C) is displayed, depending on the set point settings. Use
the buttons to change the set point or the base set point shift.
