,
therefore, the boiler supplies the heating system with hot water
at a temperature adjusted using the
and
keys,
Any room thermostats enable or disable the heating function
to adjust the temperature of the rooms. To take full advantage
of boiler performance, it is advisable to adjust the heating
temperature to a value that is just enough to obtain the desired
room temperature. As climatic conditions grow colder, the
heating temperature should be progressively increased. As
the climatic conditions grow warmer, the heating temperature
should be reduced.
