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 4hours 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.
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.

INFORMATION
There is a risk of space heating capacity shortage/comfort
problem (in case of frequent domestic hot water operation,
frequent and long space heating interruption will happen)
when selecting [6‑0D]=0 ([A.4.1] Domestic hot water
Type=Reheat only).
INFORMATION
When the DHW tank mode is reheat, the risk for capacity
shortage and comfort problem is significant. In case of
frequent reheat operation, space heating function is
regularly interrupted.
In reheat mode, you can do the following:
You can… Location

Adjust the reheat temperature.
Condition:
is displayed on the DHWtank
temperature home page.
Activate the DHWtank booster mode.
Program a booster heater allowance schedule
to restrict when the booster heater can operate.

operate during the night.
Menu structure
(Only for field supplied domestic hot water
pump for secondary return)
Program a domestic hot water pump schedule
to determine when to turn ON and OFF the pump.
When turned ON, the pump runs and makes sure
hot water is instantly available at the tap. To save
energy, only turn ON the pump during periods of
the day when instant hot water is necessary.

4.5.3 Scheduled mode
In scheduled mode (
), the DHW tank produces hot water
corresponding to a schedule. The best time to allow the tank to
produce hot water is at night, because the space heating demand is
lower.
