If the fill level of the device is too low, i.e. at level stage 0, the Fill mode is
started immediately after switching on the device. The fill mode supports the
correct filling of the device. The current level stage is displayed under Start
filling (in the menu Setup Fill mode).
An audible signal with long intervals is output from approx. the fourth level
stage to warn about any overfilling of the device. If filling continues, the
interval of the signal is shortened in the following level stage. You must end
the filling at the latest now.
If a continuous tone sounds, the device is overfilled and cannot be started.
You must drain some heat transfer liquid from the device to be able to start it
again.
To fill an external consumer, press the Standby softkey when there is su-
cient fill level to start the pump. The heat transfer liquid now pumped into
the external consumer can be refilled immediately. If the fill level drops too
far, the device automatically goes into the standby state and the pump is
switched o. This process is performed until the device and the connected
consumer are filled.
The fill mode is completed with End filling and the audible notifications are
deactivated. The fault messages for low level and high level take eect again.
After ending the filling mode, the device starts the temperature
control thermostating, provided the starting state is not set to o .
Changing the starting mode can be found in Ä Chapter 6.12.4
“Specifying the starting mode (Auto start)” on page 54.
