P11

Anti umidità elettrodi 

(Electrodes anti-

humidity)

This defines fan speed and operating mode, to avoid humidity inside 

the condensing module, which could otherwise cause the electrodes to 

malfunction (0 = disabled function, recommended value = 40) (RPM speed is 

calculated by multiplying the value displayed by 50)

P17 P17 External D.H.W / 

3-waypump 

-    With single boiler and common flow probe, it lets you choose between an 

external D.H.W pump and a 3-way one.

-    With a simple cascade, it manages a D.H.W. pump (downstream an 

hydraulic separator).
