Assortment / System Description

Monitoring and recording mandatory events and functions (e.g. "Legionella"

function).

Monitoring of maximum value:

If data point "Limit value on" > "Limit value off", the maximum value is monitored

and displayed by the event logger under "Maximum".

Logic relationships of universal inputs

The measured value at input 1, OR Logic A, gives the switch on command for

storage tank charging.

The measured value at input 1, NAND Logic B, ends charging.

Operating line Setting value

[Logic A] function OR

[Logic B] function NAND

[Logic C] function AND

[Logic A switching value 1] on 30 °C

[Logic A switching value 1] off 35 °C

[Logic B switching value 1] on 65 °C

[Logic B switching value 1] off 60 °C

Logging measuring variables
