then pauses until 10:15 am , restarts at 10:15 am,
pauses from 10:20 am to 10:30 am , and so on ...
until the end of the time window at 2:00 pm .
In this operating mode, the circulation pump
can also start outside of the time window
when hot water is being tapped. This is useful if, for
example, the time window ends at 8:00 pm and
you shower at 9:30 pm . When you then turn on the
hot water briefly, the circulation pump starts, and
you will have hot water for showering shortly
afterwards.
This runtime (outside the time window) is set in the
text menu (parameter [Circulation pump delay]).
Enter the same value as parameter [Circulation
runtime].
Heat exchanger
The tap symbol next to the heat
exchanger is only displayed if the fresh
water module is feeding hot water into the
water mains. The temperature shown
next to this is the temperature of the hot
water currently being supplied.
If no hot water is being supplied, the heat exchanger is
shown blue all the way through.
Circulation pump in operation
Optional: for [Circulation pump]
The pump symbol next to the heat
exchanger appears when the circulation
pump for hot water is in operation.
Timer [Stand-by times]
This is only displayed if option [Target value can
be set with rotary knob] is deactivated
This timer displays the set charging times of the
current day for charging the hot water tank. These time
windows are displayed as a black bar in the timer.
Timer [Circulation times]
This only appears if a circulation pump is installed
and the [Self-learning] function is deactivated.
This timer displays the set times of the current day to
operate the circulation pump. These time windows are
displayed as a black bar in the timer.

Operating modes
Ready
No hot water is currently being taken.
Working
Hot water is currently being supplied.
Buffer cold
Hot water is being supplied, but the buffer is not hot
enough to reach the configured hot water temperature.
Primary return too warm
Hot water is being supplied, but the selected hot water
temperature is being reduced because the [Primary
return] temperature in the heat exchanger of the fresh
water module is too high.
Malfunction
A temperature sensor in the fresh water module has a
defect.
Circulation
The circulation pump is in operation.
Venting
The controller has found air in the fresh water module
and automatic venting is in operation. For this, both
pumps are operated at full speed for a short period of
time to remove the air from the fresh water module.
This can also take place multiple times sequentially.
Emergency operation
The fresh water module is in emergency mode
because the admixing pump is defective. Currently, hot
water is being delivered but it is only being produced
with the buffer pump.
Without the admixing pump, calcification
protection of the heat exchangers it not
guaranteed. Protracted emergency mode can
therefore calcify the heat exchanger.
Ready (Emergency operation)
The fresh water module is in emergency mode
because the admixing pump is defective.
Without the admixing pump, calcification
protection of the heat exchangers it not
guaranteed. Protracted emergency mode can
therefore calcify the heat exchanger.
