Application Example
Task: A heating element is to keep the room temperature between 19°C and 21°C during daytime. At
night, the temperature must be lowered by 4°C.
A temperature sensor located in the room is coded for address A2 and displays the tempera-
ture on a Touchscreen.
Solution: Since the analog sensor value on A2 is already needed for displaying the temperature, we
assign the temperature sensor object - and consequently the relay controlled by the heating
element - to address A3.
For the night setback, we assign a real-time clock to A4 with the desired switching times. The
real-time clock serves as an additional address for enabling the second pair of limit values.
