Hot water
The speed of the primary pump is controlled depending
on the set hot water temperature.
ACHTUNG
High media temperatures (>60 °C) increase the
risk of corrosion and energy costs!
!
Do not set the hot water temperature higher
than absolutely necessary.
8.6.1
Setting of the temperature
If the operating function has not been locked, anyone can
select the hot water temperature in the start menu and in
the "Hot water" menu. The temperature that can be set
depends on the specifi ed temperatures "Hot water set
min." and "Hot water set max.".

8.6.2 Emergency operation
Emergency operation means that the pump is
permanently switched on.
If emergency operation has been activated, the
ring on the touch control fl ashes red and the
message "Emerg. op" appears in the display.
CAUTION
Risk of scalding due to excessively hot potable
water at the draw off points!
In emergency operation, the primary pump pumps
a constant quantity of water from the storage
cylinder through the heat exchanger. In extreme
cases, this can lead to the water at the draw-off
points almost reaching the temperature of the
storage cylinder water.
!
In emergency operation, reduce the
temperature of the storage cylinder circuit so
that the temperature in the storage cylinder
does not exceed the desired potable water
temperature.
!
Only use the emergency operation temporarily
to ensure the supply of hot potable water
on a makeshift basis. Immediately replace
the defective sensor and restore controlled
operation of the pump.
8.6.2.1
Automatic activation
Automatic emergency operation is used to ensure hot
water preparation even in the event of a sensor failure. The
speed after automatic activation is confi gurable.
8.6.2.2
Manual activation (DIP switch)
If, in addition to a sensor, the touch control panel has also
failed, emergency operation can be activated manually.
f
Set DIP switch 1 (see Fig. 7 on page 20) to "ON".
Z
Emergency operation is permanently activated. The
speed of the pump corresponds to 50 % of the pump
capacity.
8.7
User code
A user code can be entered in the "User code"
menu. Each digit of the four-digit code must be
entered and confi rmed individually. After confi rm-
ing the last digit, there is an automatic jump to
the next higher menu level.
When an "Installer" user code is active, the ring
around the touch control panel is green.
For the authorisation of the respective user
groups see par. 8.3 on page 34. The authorisa-
tions available to the respective user groups are
symbolised by the ticks in front of the functions.
