The "COMFORT" function of the appliance can be
used to increase the comfort level of the user when
drawing hot water.
This function keeps the secondary exchanger hot
during periods of boiler inactivity; this increases the
initial heat status of the water drawn, as the water is
delivered at a higher temperature.
