3.4 Domestic hot water control
CAUTION
Only for EHVH_SU_CB6W models.
When using the domestic hot water tank to produce hot
water, do NOT turn OFF the heat pump. Reason: the
electrical backup heater from the space heating circuit is
used during disinfection of the domestic hot water tank.
3.4.1 Reheat mode
In reheat mode (
),the DHW tank continuously heats up to the
temperature shown on the DHW tank temperature home page
(example: 50°C).

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.
3.4.2 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.
Example:
t
60°C
00:00 07:00

3.4.3 Scheduled + reheat mode
In scheduled + reheat mode (
), the domestic hot water control is
the same as in scheduled mode. However, when the DHW tank
temperature drops below a preset value (=reheat tank temperature –
hysteresis value; example: 35°C), the DHW tank heats up until it
reaches the reheat set point (example: 45°C). This ensures that a
minimum amount of hot water is available at all times.

To read out and adjust the desired reheat temperature (in
scheduled and reheat mode)
1 Go to [7.4.3.3]:
> User settings > Preset values > Tank
temperature > Reheat.
Result: You can read out the desired reheat temperature.
2 Press
or to adjust.
To read out and overrule the active or next scheduled desired
temperature (in scheduled mode or scheduled + reheat mode)
1 Go to the DHWtank temperature home page (Tank).
Result:

is displayed.
2 Press
or to overrule. Note: If the desired temperature is
weather dependent, you cannot change it on the home page.

To activate the DHWtank booster mode (user profile = Basic)
1 Go to the DHWtank temperature home page (Tank).
2 Press
for more than 5seconds.
