Commands outside the boiler
Externally the boiler, suitably positioned in the building
(generally by the installer or by the electrician), two devices
that the user should access to, are present. The presence
and the characteristics of these devices are prescribed by
the regulation in force.
Two-pole switch:
it is located usually close to the boiler and it's for electrically insulating the boiler itself
from the domestic mains power supply network.
Room thermostat:
it commands electrically the boiler to activate or deactivate the heating system, in
order to keep the room temperature (detected by a sensor) within a value set by the user, Regulation
in force prescribe its positioning, the temperature limits within the user can adjust it and the periods
of heating. On trade are available programmable room thermostats: most of them allow to make a
weekly programming of various temperature levels, besides special programs for various purposes.
