3.1.10. FAST H2O FUNCTION
The Fast H2O function keeps a constant
temperature in the DHW circuit within the water
heater, according to the temperature set by the
user.
The Fast H2O 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.
To activate/deactivate the Fast H2O function please
follow the instruction indicated in the paragraph
‘ACTIVE FUNCTIONS SIGNALLING CODES’.
