pump forcibly even in the absence of water, excluding the dry-running protection to allow the
loading of the pump itself.
You can customise the language of menus and alarm messages. Use the "+" and "-" keys to
change the parameter value.

Jockey pump switchgear
CAUTION
Fill the suction pipe of the pump when first switching on the switchgear
before supplying the system!
Once all electrical connections have been made and checked for correctness, close
the cover of the switchgear and power up the system. The switchgear will automati-
cally start the pump to allow the system to be filled. If the pump does not start, or
produces abnormal vibrations, check the correct connection of the pump itself and
its capacitor.
To make it easier to fill the electric pump, it is possible to keep the "+" key pressed on
the main screen, so that the pump can be forced to run without the intervention of the
dry-running protection ("Manual" mode).
The menu is divided into two levels: the user level and the installer level. The user level
is normally visible during normal operation and allows you to check the operating status
of the system, reset any errors and change the language. The various operating para-
meters at installer level are set at the factory.
These parameters are normally accessible when the device is powered.
These parameters are contained in hidden screens and are usually only changed during
installation. To access these pages, press the "+" and "-" keys simultaneously for
5 seconds. After calling up the background menu, scroll through the pages with the ar-
row key ">>". Use the "+" and "-" keys to change the parameter value. To return to the
main screen, press the "+" and "-" keys simultaneously for 5 seconds.
Description
This parameter can be used to set the operating mode in which Brio Top Fire con-
trols the start and stop of the pump. In "P+F" operating mode (pressure + flow)
the pump is started when the pressure drops below the set value of P
pressure) and is stopped when the water flow is almost zero. In this condition the
resulting pressure inside the system will be equivalent to the maximum delivery
head of the installed pump.
CAUTION!
The system can also operate in P+P mode (pressure + pressure). The pump is star-
ted at the set value of P and is stopped when the pressure in the system reaches
min
the P value (stop pressure). In this mode it is absolutely essential to install an
max
expansion vessel suitably sized according to the characteristics of the system. In
both operating modes, dry-running protection is active and is triggered when the
water flow is zero and the pressure in the system is lower than the P
