INSTALLATION AND STARTUP
Install the device on a wall near the pump (fig. 1).
Connect the supplied pressure sensor, make the electrical connections and energize.
Arrange the use of an expansion tank sized according to the hydraulic characteristics of the system.
To startup the pump, follow the instructions that will appear in sequence on the display of the device:
- Language selection.
- Pump motor ampere setting.
- Minimum flow acquisition.
- Setting of the working pressure and restart pressure if different from factory setting: system pressure 3 bar -
restart pressure 1,5 bar.
- It is now possible to start the pump
FIG.1
AUTOMATIC RESTART AND ANTI-JAMMING FUNCTION
In case of stopping due to a water shortage, the devices will automatically make 10 double attempts to rearm over the 24
hours following the failure, each lasting approximately 5 seconds to allow the pumps and the system to reload if possible.
The user can try to rearm the devices at any time by pressing the Restart button.
If for any reason the pumps remain idle for 24 consecutive hours, the devices will carry out a start-up of the pump motor for
about 5 seconds without affecting the normal operation of the unit.
In case of a temporary blackout, the pressure set will automatically rearm once the electricity returns.
