Notes
Minimum frequency at which you allow the pump to
work.
Maximum frequency at which you allow the pump
to work.
When the pump in operation reaches this frequency it
sends a command to the auxiliary to start up.
Time from the moment the condition of parameter 5.09
occurs until the auxiliary pump starts.
Time from when a system of two or more pumps
is working below parameter 1.4 until the auxiliary
pumps stop.
We can use the digital input as a system start-stop by
closing the input circuit, or by opening it if we select
the INV option.
It can also be used as a second set pressure in the same
way. Closing the circuit of the programmed input, the
system will ignore the second set pressure (parameter
5.05). The operation described is the reverse if we choo-
se the INV option.
"Flow Sensor NC" can be selected when a flow sensor
is available, which will stop the pump when the contact
is opened.
Selecting "Unused" will not affect the system.
See parameter 5.12
The aim of this parameter is to enable signals remotely.
OFF: The relay is never activated.
Alarm (NO): The relay closes before an alarm.
Alarm (NC): The relay opens before an alarm.
Running: The relay is energised when the unit is
running.
External stop: The relay is energised when there
is an external stop. (For this condition we must have
programmed a digital input as "·Start/Stop").
Dry running: The relay is energised if the converter
detects dry running.
Clock (NO): The relay closes depending on the time
data programmed in parameters 5.16 to 5.21.
Clock (NC): The relay opens depending on the time
data programmed in parameters 5.16 to 5.21.
