6.4. Electrical installation
The electrical mains must be single-phase at 230v 50Hz, and a two-pole circuit
breaker must be installed between the mains and the boiler.
The boiler must always be earthed.
The elements external to the boiler as well as the power supply are carried out
from the rear by means of connectors. This facilitates future work and maintenance.
The room thermostat connection is programmed to make a demand when the
contact is closed.
The "Pump" and "3-way valve" outputs can handle a maximum of 3A.
The connections are as follows:

purpose.
If the installation has an inertia tank and you want the boiler to control it, you will
have to order an extra probe for this purpose.
