If during the autotest (whatever pump is operating) the minimum pressure switch (CONV.L.SWITCH)
installed on the set trips, the autotest is definitively interrupted and the set resumes working in automatic
mode.
The display shows the message AUTOTEST FAIL P#.
CONV.L.SWITCH intervention is delayed by the time set on the parameter AUX3 IN DELAY.

Sometimes in the systems there is a fall in pressure caused by load losses along the pipes and these
increase when the required water flow increases.

To compensate system load losses it is possible to enable a control that supplies a pressure proportional
to the load. A direct measurement of the flow is not taken, but it is believed that it is proportional to the
number of pumps running.
When each duty pump after the first is started, the UPPER and LOWER thresholds are increased by the
value indicated in the COMP. THRESHOLD parameter.
The jockey pump is excluded.
