board (available on request). The settable values are:
OFF
"OFF" input disabled
"ERR" error signal: on closure of the auxiliary input, the pump will immediately shut down and "External error" will appear on the
screen. Use this function if it is necessary to stop the inverter due to an external error.
"2 <-"
the auxiliary input is used for remote control of start-up and shut-down of the electric pump; if the same setting is also active
for the parameter "Aux. Con", it is necessary to close both contacts to start the motor (AND logic)
"3 X2" the auxiliary input is used to control a second pressure set-point (Pmax2); the auxiliary input is used to control a second pressure
set-point (maxP2); if the same setting is also active for the parameter "Aux. Con", it is necessary to close one of the two contacts to
control the second set-point (OR logic)

(available on request). The settable values are:
OFF
"OFF" output disabled
"ERR" error: the output is activated (closed contact) in the presence of any error in Sirio
"P.ON" pump in operation: the output is activated (contact closed) whenever Sirio controls the pump start-up
"AUXauxiliary pump: enables control of an auxiliary pump at a set speed which starts up when the pump controlled by Sirio is no longer
able to fulfil the needs of the system. The output is activated (closed contact) when the frequency of the pump is at the maximum
admissible value and the pressure drops below the minimum start-up value. Caution: it is not possible to connect a load superior to 0.3°
to the output relay! Consult the documentation supplied with the I/O auxiliary board for the correct connection to an external control
panel.
(2.5)Delay on stop: this parameter enables the user to set after how many seconds the electric pump is stopped following
Stop.del
the closure of all utilities. If continuous start-up and stop of the pump is detected with low flows, increase the delay
10.0sec
before stopping to make operation more uniform. It may be useful to increase this parameter also to avoid excessively
frequent intervention of the dry-running protection, especially in submerged pumps or on those with problems in self-
priming. The factory setting is 10 seconds.
(2.6)Auto-reset-interval: during operation of the electric pump if a temporary absence of water on intake is detected,
Reset
Sirio will shut off power to the motor to avoid it being damaged. On this screen it is possible to set how many minutes
15 min
the device will remain stopped before carrying out an automatic restart to check for the availability of water on intake.
If the attempt is successful, Sirio will automatically exit from the error condition and the system resumes normal operation; if this is not
the case, another attempt be will be carried out after the same time interval. The maximum settable interval is 240 minutes (recommended
value is 60 min).
(2.7)Auto-reset test n.: this parameter sets the number of attempts that Sirio will perform to resolve a stop condition

due to dry running. Once this limit has been exceeded, the system shuts down and the user's intervention is required. If

this value is set to zero, the auto-reset function is switched off. The maximum number of attempts allowed is 20. Use
buttons + and – to modify the parameter value.
