Water Pump Control
When a circuit is active (in Comfort, Economy, Antifreeze mode), the associated pump in the “Circuit Water Pump Management” section is switched on:
...
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.
...
If the Temperature Limit on the Circuit Page is not set (=0), but the parameters for overheating control in Configuration 2 are not taken into accountset, once the limit time past the overheating alarm will appear if the circuit is ON! So even if this alarm is not interesting for that specific circuit insert anyway a value different from zero!
Vice versa, if the parameters in Configuration 2 are not set, but the limit temperature is set, the overheating control does not work. All 3 parameters for overheating control must be set, otherwise the alarm will not appear.
...
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.
