1.31 KITS AVAILABLE ON REQUEST.
• System shut-off valves kit (on request). The
Basic Magis Pro is designed for the installation
of system interception cocks, to be placed on
the flow and return pipes of the connection
assembly. This kit is particularly useful for
maintenance as it allows the Basic Magis Pro to
be drained separately without having to empty
the entire system.
• Connection unit (on request). The system
is dispatched from the factory without the
connection unit. The kit includes the pipes
and fittings for connecting the Basic Magis
Pro. It is also possible to select the connection
choosing between the kit with bottom, rear or
side connection.
• Solar heating system coupling kit. The system
is designed to be combined with the thermal
solar system as supplementary energy source.
The coupling kit is supplied complete with
expansion vessel, circulation unit and solar
control unit.
• Inertial storage kits. Check which inertial stor-
age tank kit to install according to the type of
product.
1.32 CIRCULATION PUMP (SOLAR
THERMAL SYSTEM COUPLING KIT).
The units are supplied with circulating pumps
fitted with speed regulator.
These settings are suitable for most systems.
In fact, the pump is equipped with electronic
control to set advanced functions. For proper op-
eration one must select the most suitable type of
operation for the system and select a speed in the
available range, with a focus on energy savings.
Display of operation status (Fig. 46).When the
pump starts, the LED (2) lights up green for
about 2 seconds, followed by short flashing at
great intensity to then switch off during normal
operation. The LED (3) only lights up in PWM
setting, not used in the application. The three
yellow LEDs (4) indicate the three constant
curve speeds.
Selection of operating mode.
The operating mode is always visible and indica-
ted by the 3 yellow LEDs (4).
Info: All the LEDs are off when the pump is
not powered.
Press the button (1) to change operating mode.
Every time the button is pressed, all the possible
functions are scrolled cyclically according to the
following table:

- Constant curve: the pump works maintaining
system head constant. The pump working point
will move up or down according to the system's
demand.
- PWM profile: do not use this operation mode.
Attention: if this profile is selected, the pump
will stop.
For the "Basic Magis Pro" the pump is set at
"Constant curve speed 3" by default.
Real time diagnostics: in the event of malfunc-
tion the LEDs provide information on the pump
operation status, see table (Fig. 48):
