9 Mixer module
In addition to the direct HC, the heating system can be extended by
additional HCs using EHS157068 mixer modules. These additional
HCs can be configured independently of the direct HC. The configur-
ation is similar to the configuration of the direct HC (see
Chap. 4 ).
Only a limited selection of parameters and functions is available (see
Chap. 9.2 ).
The optional EHS157068 mixer module does not have its own con-
trol unit. For configuration and operation, it must be connected via a
CAN bus line to the RoCon+ controller installed in the heat generator
or a EHS157034 room station. The mixer module can be operated in
terminal mode from both operating units (see
Chap. 4.8 ).
A unique device ID (≥ 1) must be set on the address switch of the
mixer module (see
Fig. 9-1 ) for the HC to be controlled by this mixer
module, which must be synchronised with the [Heating circuit as-
signment] parameter of the mixer module (see
Tab. 4-7 ]).

The current operating status can be determined directly on the
EHS157068 mixer module (see
Fig. 9-2 ).

(terminal function)
Fig. 9-3 Mixer module start screen
The start screen for the mixer module ( Fig. 9-3 ) is a reduced version
of the RoCon+ HP start screen. The meaning of the icons is the
same
Tab. 3-3 , but the mixer temperature is the only system temper-
ature displayed ( Fig. 9-3 , item 1).
The start screen for the mixer module is displayed in the menu
[→ Main menu → Terminal → Mixer #X]. Briefly pressing the rotary
switch switches to the mixer menu. A long press of the rotary switch
switches to the menu of the local control panel.
