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.
When the high domestic hot water temperature can be a potential risk for human
injuries, a mixing valve (field supply) shall be installed at the hot water outlet
connection of the domestic hot water 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.
CAUTION
Be 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.
CAUTION

operation based on a weekly program. Advice: In order to avoid unsuccessful
disinfection function, at least allow the booster heater (by the weekly program) for
minimum 4hours starting from the scheduled start-up of disinfection. If the booster
heater is restricted during disinfection, this function will NOT be successful and the
applicable warning AH will be generated.
