Operating instructions

To fill an external consumer, press the Standby softkey when
there is sufficient fill level to start the pump. The heat transfer liquid
now pumped into the external consumer can be refilled immedi-
ately. If the fill level drops too far, the device automatically goes
into the standby operating mode and the pump is switched off. This
process is performed until the device and the connected consumer
are filled.
The fill mode is completed with End filling
and the audible notifica-
tions are deactivated. The fault messages for low level and high
level take effect again.
After ending the fill mode, the device starts the tem-
perature control provided the start operating mode is not
set to off . Changing the start operating mode can be
found in
Ä Chapter 6.11.4 ‘Specifying starting mode
(Autostart)’ on page 55.
