HYDRAULICS New 3-way motorized valve – Supplier “Giannoni”
HYDRAULICS Heating NTC Supplier “EPCOS” Sparkling Igniter Supplier “ANSTOS” DHW NTC Supplier “EPCOS” The same features as in current version
ELECTRONICS - main PCB Current Micra 2 Micra Condensing New Micra 2 Micra Condensing Supplier “Honeywell” Supplier “Nordgas” Same features and technical characteristics as in current version
ELECTRONICS - main PCB 6 MICROSWITCHES
ELECTRONICS - main PCB • How will microswitches be on boiler? • New boilers = All OFF (SW1 based on gas type) • Spares = All OFF SW6 = OFF --- Water automatic fill-in not enabled SW6 = ON --- Water automatic fill-in enabled (Must be OFF for your boilers) SW5 = OFF --- Working pump STANDARD SW5 = ON --- Working pump OFF during heating demand SW4 = OFF --- Max achievable temp on DHW demand OFF 75°C / ON 65°C (Standard) SW4 = ON --- Max achievable temp on DHW demandOFF Tset + 3°C / ON Tset +2°C SW3 = OFF --- Delay of 3 minutes before restarting, after heating demand SW3 = ON --- No delay setted SW2 = OFF --- Range temperature setting TA1 Standard: 35°C / 78°C SW2 = ON --- Range temperature setting TA1 Ridotta: 25°C / 45°C SW1 = OFF --- boiler works with NATURAL GAS SW1 = ON --- boilerworks with LPG
