WARNING
Be aware that the domestic hot water temperature at the hot water tap will be equal
to the value selected in field setting [2-03] after a disinfection operation.

connection of the storage tank. This mixing valve shall secure that the hot water
temperature at the hot water tap never rise above a set maximum value. This
maximum allowable hot water temperature shall be selected according to the
applicable legislation.

Make sure that the disinfection function start time [5.7.3] with defined duration
[5.7.5] is NOT interrupted by possible domestic hot water demand.
