Domestic hot water control

Only applicable in case an optional domestic hot water tank is
installed.
Configuring the desired tank temperature
The domestic hot water can be prepared in 3 different ways. They
differ from each other by the way the desired tank temperature is set
and how the unit acts upon it.
# Code
[A.4.1] [6-0D] Domestic hot water Type:
▪ 0 (Reheat only): Only reheat operation
is allowed.
▪ 1 (Reheat + sched.): The domestic hot
water tank is heated according to a
schedule and between the scheduled
heatup cycles, reheat operation is
allowed.
▪ 2 (Scheduled only): The domestic hot
water tank can ONLY be heated
according to a schedule.
See "8.3.2 Domestic hot water control: advanced" on page 61
more details.
INFORMATION
There is a risk of space heating (cooling) capacity
shortage/comfort problem (in case of frequent domestic hot
water operation, frequent and long space heating/cooling
interruption will happen) when selecting [6‑0D]=0 ([A.4.1]
Domestic hot water Type=Reheat only) in case of a
domestic hot water tank without an internal booster heater.
Maximum DHW temperature setpoint
The maximum temperature that users can select for the domestic
hot water. You can use this setting to limit the temperatures at the
hot water taps.
INFORMATION
During disinfection of the domestic hot water tank, the
DHW temperature can exceed this maximum temperature.
INFORMATION
Limit the maximum hot water temperature according to the
applicable legislation.

Preset leaving water temperature
You can define preset leaving water temperatures:
▪ economic (denotes the desired leaving water temperature which
results in the lowest energy consumption)
▪ comfort (denotes the desired leaving water temperature which
results in the highest energy consumption).
Preset values make it easy to use the same value in the schedule or
to adjust the desired leaving water temperature according to the
room temperature (see modulation). If you later want to change the
value, you ONLY have to do it in one place. Depending on whether
the desired leaving water temperature is weather dependent or NOT,
the desired shift values or the absolute desired leaving water
temperature should be specified.
NOTICE
The preset leaving water temperatures are ONLY
applicable for the main zone, as the schedule for the
additional zone consists of On/OFF actions.
NOTICE
Select preset leaving water temperatures in accordance
with the design and selected heat emitters to ensure the
balance between desired room and leaving water
temperatures.
