Temperature Sensor KNX T-UN • Version: 27.01.2020 • Technical changes and errors excepted.
In case of a common control variable for heating and cooling, 0 is always transmitted
as a fixed value.
PI control with predetermined application:
This setting provides fixed parameters for frequent applications.
Now specify what should be sent when the control is blocked. Set a value greater 0
(=OFF) to receive a basic heating level, e.g. for floor heating.
On release, the control variable follows the rule again.
In case of a common control variable for heating and cooling, 0 is always transmitted
as a fixed value.
2-point-control (only stage 2):
2-point-control is used for systems which are only set to ON or OFF.
Enter the hysteresis that prevents frequent on/off switching of temperatures in the
threshold range. Then set whether a 1-bit object (on/off) or an 8-bit object (on with per-
centage/off) should be used.
