Filling The System; Operating Limits; Commissioning The Hydronic Module (Ignition) - Immergas MAGIS PRO ERP Instruction And Recommendation Booklet

1.11 FILLING THE SYSTEM.

Once the hydronic module is connected, fill the
heating system using the filling cock (Fig. 1-33
and 1-4). Filling must be done slowly to allow
the air bubbles in the water to escape through
the vents in the hydronic module and the heating
and air conditioning system.
The hydronic module has one incorporated automatic
vent valve located on the circulator and another on
the central heating manifold. Make sure that the hoods
are loosened.
The filling cock must be closed when the hy-
dronic module pressure gauge indicates approx-
imately 1.2 bar.
N.B.: during these operations, enable the "Vent-
ing" functions by setting the "M01" parameter to
ON, which lasts about 18 hours (see the "P.C.B.
programming" paragraph).
System minimum water content.
Minimum water content is mainly important to
provide proper execution of defrosting cycles.
To this end, the minimum amount of water to
guarantee is 7 l/kW for any type of system.
N.B.: it is also important to check that the
dehumidifier line has a minimum of 3 l/kW
(dehumidifier hydraulic circuit connection).

1.12 OPERATING LIMITS.

The system was designed to work in a specific
range of temperatures and at a specific maximum
flow temperature. The graphic (Fig. 1-9) shows
these limits.

1.13 COMMISSIONING THE HYDRONIC
MODULE (IGNITION).
The following requirements must be met to
commission the hydronic module in order to
issue the Declaration of Conformity, if required
by the technical standards in force (the following
operations must be done only by professionally
qualified personnel and in the presence of pro-
fessionals only):
- check that the internal system is properly sealed
according to the specifications set forth by
technical regulations in force;
- check connection to a 230V-50Hz power
mains, correct L-N polarity and earthing
connection;
- switch on the hydronic module and check for
proper ignition;
- check the operation of the main switch located
upstream of the hydronic module and on the
module itself;
Should even just one of these checks have a
negative outcome, the system must not be
commissioned.
