press the "-" button until the word "OFF" appears on the bottom line of this page.
Pmax2: this page is only disp layed if the "AUXIL IAR Y CON TACT "
parameter is set on "3" (second set-point function); this parameter is used
to set the secondary set-point of the de vice. When the auxiliary contact is
externally closed the Pmax2 pressure value becomes the new set-point
according to which the Press•o•Matic adjusts the speed of the motor pump.
Pmi n: this value represents the pump restart pressure. When any user
appli ance is switched on, the pump does not start up until the system
pressure has dropped below the Pmin value. Once the motor has s tarted
running, its rotation speed is regulated to keep the pressure as near as
possible to the value set for the Pmax. The minimum differential settable
Stop delay: Use this parameter to define after how many seconds the motor
pump should stop once all the functions have been closed. If when the
flows are low the pump continuously swi tches on and off, increase the
switching off delay so that the operation is smoother. Increasing the
parameter can also be useful to stop the frequent triggering of the dry run
Auto-reset i nterval: if the pump experiences a temporary shortage of
intake water while it is operating, the Press•o•Matic cuts off the power to
the motor to prevent it being dam aged. From this screen page, a device
automatic restart time can be set (in minutes) at the end of which a test will
be run to see if the in take water supply has returned. If the test is
successful, the Press•o•Matic automatically qui ts the error status and the
Auto-reset test n.: this parameter sets the number of attempts that the
Press•o•Matic will make 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 au to-reset function
is s witched off. The maximum number of attempts allowed is 10. Use the
+ and – buttons to alter the parameter setting..
Maximum number of starts in an hour: From this page you can set the
maximum number of starts of the motor pump in one hour before the
intervention of the Serious Leakage alarm. Only short starts are counted, in
other words those which are not followed by the suction of minimum 2.5
litres/min of water. If the Serious Leakage alarm is activated too often or
without reason, then it is ad vis able to increase the parameter on this page
