5.3 Switching on device for the first time and filling with water
5.3.1 Fill mode
If the filling mode is active, the words " filling mode "
appear on a yellow background in the basic window.
The device does not heat or does not cool.
The device has a program for convenient filling with heat transfer
liquid.
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 fol-
lowing 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 sufficient 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 off. This process is per-
formed 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 filling mode, the device starts the tem-
perature control thermostating, provided the starting
state is not set to off . Changing the starting mode can
be found in Ä Chapter 6.12.4 ‘Specifying starting mode
(Autostart)’ on page 64 .
