Temperature resolution is 0.1°C.
21.3°C gives the value 21.3 in the inter-
nal variable.
If the value is transferred to the PCD, the
format "DEC1" must be selected in the
Web Editor.
As a result, the value is stored as 213 in
the PCD.
Calibrating the temperature sensor:
The temperature sensor must be calibrated in the device's Setup Menu when it is used for the first
time.
To do this, you need to open the panel's Setup Menu as described in
Chapter 5.3.5
.
In
Setup Menu -> System -> Special -> Calibration
, a correction value for the installation location
must be defined.
To do this, you need to measure the temperature at the installation location using an external
measuring device. The temperature value measured must be entered in the Setup Menu. The cor-
rection factor is calculated and saved by the device itself.
IMPORTANT:
To ensure that the system functions correctly, the installation location must be taken into account
when using the temperature sensor as described in Chapter 1.5.1.
