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 [A.4.4.3]
with defined duration [A.4.4.5] is NOT interrupted by
possible domestic hot water demand.
CAUTION
The booster heater permission schedule is used to restrict
or allow booster heater 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.
