Water Pump Control
...
The way these inputs are interpreted, depends on the setting of parameter P. Twin/P. Twin Blk NC.
Note
It is possible to achieve the same result by inverting the digital input Water Pump A Input Block: select REG / IA1 instead of REG IA1, as indicated in the example.
...
For both valves, a dead band PID can be considered, which is always set in Configuration 2:PHOTO TBD
...
The dead band (delta K) is a range within which no corrections are made to the PID output, essentially ignoring the error. If it is = 0, it is not taken into account.
...
Once the overheating alarm is reached, it is not enough for the circuit probe to cool down, the system must also be switched off and on again!

The indicated times are added together, so if 10 seconds is entered for each, if within 30 seconds the temperature does not fall below the maximum allowed, the system will signal an overheating alarm for circuit x.
Warning
The overheating alarm also occurs if the same circuit is called upon to work in both heating and cooling mode at the same time.
