Electrical connection of module generators
Each generator comprising the modular assembly is supplied pre-wired for both the adjustments and
the safety devices. It can therefore operate on its own (see wiring diagrams of paragraph 4.5). Connect
each generator to a single-phase electric line of 230 V ~ 50 Hz, neutral phase, via a terminal board or
regular plug, inserting fuses max. 2 A between the boiler and the line.
It is always important to connect each generator to a good earthing system.
If you want the generators forming the modular assembly to work in cascade, you will need to
use an electronic sequence controller.
Electronic sequence controller (supplied on request)
Each generator forming the modular assembly is fi tted for installing an electronic sequence controller
(Fig. 10) that can be secured to the instrument panel by simply removing the plug 1 (Fig. 1). To access
the components inside the instrument panel, see paragraph 2.5.
A single sequence controller is needed for each set of module generators.
The instructions manual for connecting, adjusting and programming the electronic sequence controller
as well as for the various types of system is contained in the controller package.

Fundamental functions of the electronic sequence controller
- Reduction interlocked with outside temperature (climate control).
- Programming on two different temperature levels (economy and comfort).
- Daily programming with up to three actions on one level and three on the other.
- Setting the daily program for the whole week.
- Rotating the action sequence every 24 hours to distribute module wear.
- Smart forced starting.
- Smart ON-OFF time control in the action cycle.
- Checking pump starting according to the outside temperature.
- Self-diagnosis for malfunctioning.
