SYSTEM COMPONENT ADDRESSING
System pump on the secondary and area valves
Separator between primary and secondary circuit.
In the secondary circuit, a circulator is activated on energy request by
the system.
I/O MODULE
Booster pumps
Booster pumps combined with each system circuit.
The outputs of I/O modules activate the specific circulator, depending on
the real requirement of energy by the components of that hydraulic
circuit.
Management of the cooling only unit
If the boiler is used in conjunction with a unit to produce cooling
energy only the MIOX module will also switch circuits
depending on the system's operating mode (heating or
cooling).
Stand-by normally open contacts towards chiller.
Powered contact towards boiler.
