ENERGY TOP W> > > Heating division> SPECIFICATIONSSETTING AND CONTROLThe ENERGY TOP W series boilers boast an evolved electronics that can manage as standard up to two direct heating zones or an eventual storagecylinder with one direct zone, without requiring additional electronic controllers.PS: Diagrams are for mere example only and need to be verified according to the specific installation.> MIXED CIRCUIT WITH PRIORITY TO THE STORAGE TANKLegionella disinfection signalRecirculationtimerEach boiler or cascade of boilerscan be connected to an outdoortemperature probe for flowtemperature compensationoperation. MASTER-SLAVEinterconnection between the boilerspermits multiple cascadeconfigurations without requiringadditional control boards.> MIXED CIRCUIT WITH PRIORITY OR SIMULTANEOUS OPERATION OF THE STORAGE TANKLegionella disinfection signalRecirculationtimerThe Legionella protection function,after a programmable time interval,ensures the temperature inside thestorage cylinder remains at 65°Cfor 15 minutes. When Legionellaprotection is active, the boiler’selectronics sends an output signal(voltage-free contact) that can beused to control a recirculating pump.This ensures the entire water contentin the circuit is protected.In the case of combined systems (without diverting valve) domestic hot water storage cylinder can be heated simultaneously with the centralheating or as a priority function depending on the characteristics of the system.11
