The microSYSTEM is able to be connected to a specially designed
kit for the management of D.H.W. production. This kit gives priority to
production of D.H.W. unlike traditional systems where the boiler
power is split between C.H. and D.H.W. This generally enables a
smaller storage cylinder to be chosen as the boiler's full output will be
channelled into the cylinder allowing for a quick heat-up.
The kit (ARISTON part number
ARISTON supplier.
The kit consits of:
1)
Electronic module able to plug into the boiler's P.C.B;
2)
3-way priority valve with actuator for connection to the boiler's
flow outlet;
3)
A limit thermostat (80˚C) to check the water temperature of the
heating flow to the cylinder, to be installed within the boiler;
4)
