1.1.9. SYSTEM ACCESSORIES
DIVERTER VALVE KIT
The kit allows combining the thermal generator
with a remote boiler for the production of domestic
hot water (cod. 26097LP, fig. 1).
In this configuration, it is possible to manage the
domestic circuit in an independent manner, by
implementing a diverter valve which ensures the
power supply of the serpentine upon the pre-
heating request of the boiler.
The kit is completed with a probe for the external
boiler and with a power supply cable of the diverter
valve which is connected directly to the electronic
board of the generator.
HYDRAULIC SEPARATOR
In order to always ensure to the heat generator an
operation without problems related to two low heat
capacities (due, for example, to closed radiators or
to impurities of various type), it is strictly necessary
to install a trip unit, as an alternative, a heat
exchanger which separates the hydraulic circuit.
Choosing a separation system in the detriment of
another is exclusively imposed by the type of the
system.
In case of a new system or in case of replacement of
the generator with the possibility to wash the water
pipes, it is recommended to install a hydraulic
separator (code 12-01735, fig. 1).
The hydraulic separator creates an area with
reduced load loss, which allows hydraulically
rendering independent the primary and secondary
circuits connected to it. With the hydraulic separator
you can thus have a production circuit with constant
heat capacity and a distribution circuit with variable
heat capacity, operation conditions typically specific
to modern air-conditioning systems.
