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.
