4.5 Domestic hot water control
4.5.1 About domestic hot water control
Your system layout may or may not contain a domestic hot water
tank. When no tank is installed, the boiler provides domestic hot
water instantly. When, on the contrary, a tank is installed, domestic
hot water control is different depending on the DHW tank mode set
by the installer:
▪ Reheat mode
▪ Scheduled mode
▪ Scheduled + reheat mode
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.
