position).
8 Leave the circuit pressurised. Any pressure drop indicates a leak
in the system.
9 Set the functioning pressure in the circuit at 1.5 bar +
0.1 bar for every metre in the distance between the so-
lar collector and the expansion vessel (practically, set the
same pressure between expansion vessel and system).
N.B.: Do not exceed 2.5 bar.
10 Switch the solar pump on at a maximum speed and make it
function for at least 15 minutes.
11 Disconnect the filling pump and close the fittings using the
relevant screwing plugs.
12 Open the ball valve above the pump completely.
Do not fill the system in conditions with strong insolation and
with the manifolds at high temperatures.
Make sure that all air bubbles have been completely eliminated.
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 storage 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 ad-
vanced functions. For proper operation 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. 57).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 ope-
ration. 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 indicated 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 con-
stant. 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 malfunction the LEDs pro-
vide information on the pump operation status, see table (Fig. 59):
