Setting parameters
Temperature Sensor KNX T-AP
• Version: 27.01.2020 • Errors excepted. Subject to technical changes.
If the setpoint is set via communication object:
A starting setpoint value is defined as well as a temperature range in which the setpoint
value may be changed.
6.5.1. Heating control level 1/2
If a heating control mode is configured, one or two setting sections for the heating lev-
els are displayed.
In the 1st level, heating is controlled by a PI control, which allows to either enter control
parameters or select predetermined applications.
In the 2nd level (therefore only in case of 2-level heating), heating is controlled via a PI
or a 2-point-control.
In level 2, the setpoint difference between the two levels must also be specified, i.e. be-
low which setpoint deviation the second level is added.
Specified setpoint using
Communication object
The last communicated value should
• not be retained
• be retained after power restoration
• be retained after power restoration and
programming (not to be used for first
commissioning)
Start setpoint (heating) in 0.1°C
valid until first call
(only if the last retained value is "not"
retained, or retained "after power restora-
tion")
-300 … 800; 200
Object value limit (min) in 0.1°C
-300 … 800; 140
Object value limit (max) in 0.1°C
-300 … 800; 250
Start setpoint (cooling) in 0.1°C
valid until first call
(only if the last retained value is "not"
retained, or retained "after power restora-
tion")
-300 … 800; 200
Object value limit (min) in 0.1°C
-300 … 800; 140
Object value limit (max) in 0.1°C
-300 … 800; 250
Type of setpoint change
