9 Mixer module
In addition to the direct HC, the emitter type can be extended by ad-
ditional HCs using mixer modules EHS157068. 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 to the
RoCon+ controller installed in the heat generator or to a EHS157034
room station via a CAN bus line. 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. 4-10 ]).

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. 3-4 , 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.
