6.3 DHW Operating Modes
Three DHW operating modes can be activated pressing the DHW
function button.
ON ( LED lit above the DHW button) The appliance will1.
always maintain a minimum heat exchanger temperature to
assure instant delivery of hot water.
ECO ( LED lit above the DHW button) The appliance2.
will learn when to maintain a minimum heat exchanger
temperature during times with typical domestic demands,
learned over the past 3 days of use.
OFF (no LED lit) - The appliance will not maintain a minimum3.
heat exchanger termperature. This will delay the delivery of hot
water.
In applications in which the DHW is not utilized or the
DHW demand is minimal, set the DHW function to OFF
