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 anti-legionella heater operation based on a weekly
program. Advice: In order to avoid unsuccessful
disinfection function, at least allow the anti-legionella
heater (by the weekly program) for minimum 4 hours
starting from the scheduled start-up of disinfection. If the
anti-legionella heater is restricted during disinfection, this
function will NOT be successful and the applicable warning
AH will be generated.
INFORMATION
In case of error code AH and no interruption of the
disinfection function occurred due to domestic hot water
tapping, following actions are recommended:
▪ When the Domestic hot water > Type > Reheat or
Reheat + sched. is selected, it is recommended to
program the start-up of the disinfection function at least
4 hours later than the last expected large hot water
tapping. This start-up can be set by installer settings
(disinfection function).
▪ When the Domestic hot water > Type > Scheduled only
is selected, it is recommended to program a Storage
eco 3 hours before the scheduled start-up of the
disinfection function to preheat the tank.
