2.9 FastH2O function
The
FastH2O
system guarantees the immediate D.H.W supply at the requested temperature in instantaneous
boilers with secondary DH.W plate exchanger.
Functioning
: the domestic heat exchanger is constantly kept at the adjusted temperature; the hot water, passing
through the pre-heated plates of the heat exchanger, reaches the water taps at the requested temperature.
The FastH2O function offers three advantages:
• the hot water is immediately supplied at the requested temperature.
• unnecessary delays are avoided by increasing the comfort of the final user.
• water wastes are limited waiting that the water reaches the right temperature.
FastH2O activation/deactivation
: if the parameter 01 is set on the 01 value, i.e. instantaneous boilers secondary
DH.W plate exchanger, the“FastH2O” function can be activated/deactivated by pressing simultaneously and for 7
seconds, ‘
’ and ‘
’ buttons (of D.H.W temperature setting). With its activation, “Fast H2O” will be visualized
on the display.
