13.3 A. Connection of the 24V or 230V water basin filling N.C. solenoid valve (supplied
loose for installation by others) (*)
In the case of HEF2 series of recirculated water, the maximum level must manage this solenoid valve. It is
used as a security system in the event of a possible failure of the float valve. It must not be used for regulating
the water feed.
The float valve is the responsible for the regulation
.
(*) In the HEF2 series of
recirculated water this solenoid
valve must always be installed
upstream of the float valve.
In the HEF2 series-DW (Direct
Water),
this
solenoid
valve
manages the water feed of the
irrigation system (it will be
supplied assembled on the unit).
Eliminates the standard 1/2” ball
valve and makes it impossible for
the 3-way motor-zone valve to be
assembled.
