"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
"AUX" auxiliary 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.

Input function on the I/O board: choose the function associated to the digital input of the auxiliary I/O board

The settable values are:
Delay on stop: this parameter enables the user to set after how many seconds the electric pump is stopped
following the closure of all utilities. If continuous start-up and stop of the pump is detected with low flows,
increase the delay 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.
Auto-reset-interval: during operation of the electric pump if a temporary absence of water on intake is
detected, Sirio will shut off power to the motor to avoid it being damaged. On this screen it is possible to set
how many minutes 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
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
Total automatic reset: when set to ON, the automatic reset function is active for any error, in addition to dry-
running, detected by the system. Caution: the automatic and uncontrolled reset of some errors (for example,
overload) could over time cause damage to the system and to Sirio. Always take great care when using this
function.
