e above example refers to a boiler equipped with an ISPESL
safety kit and a distribution manifold. e system consists of
two, low temperature mixed zones, a high temperature zone
and a storage tank for the production of domestic hot water.
e system is controlled by a zones and cascade regulator (2)
that controls the storage tank directly, two zone managers (3)
that control the two low-temperature zones and a modulat-
ing room thermostat (4) that controls the high temperature
zone.
