3.5 - MOUNTING OF THE UNIT
Before connecting the unit, make first:
a) A careful washing of all the pipings with a suitable product,
in order to eliminate the metallic residues of working and
welding, of oil and grease that could damage and alterate the
unit operation.
For the mounting of the unit:
- Once choosen the position of the thermal module, drill the
fixing holes as shown in the picture of page 11. l
3.6 - HYDRAULIC CONFIGURATIONS
The thermal module M 3000 S can be used alone or con-
nected together with other modules up to a maximum of
14
modules.
A module makes the function of main controller (MASTER); its
duty is the collection of the requests from other secondary
modules (SLAVE) and the control of the boiler.
Each module can be connected to its own, optional, modula-
ting room thermostat (REGOLAFACILE).
Minimum configuration (1 thermal module)
Maximum configutaion (14 thermal modules
- Fix the unit to the all using suitable screw anchors (not sup-
plied).
- Mark the position of flow and return of the different circuits
(boiler M - R, high temperature M1 - R1, mixed temperature
Mm - Rm).
HEATING
The heating flow and return of the boiler must be connected to
the Thermal Module as shown in the picture (upper side).
From the lower side there are:
-
R1 = Return from high temperature heating circuit
- M1 = Flow to high temperature heating circuit
- Rm = Return from low temperature heating circuit (floor
heating circuit)
- Mm = Flow to low temperature heating circuit (floor hea-
ting)
