3.7.11 Connection of optional RoCon system
components
The optional RoCon devices must be connected to the indoor unit
via a 4-wire CAN bus cable (connection J13).
For this, we recommend shielded lines with the following character-
istics:
▪ Standardisation according to ISO 11898, UL/CSA type CMX
(UL 444)
▪ PVC outer sheath with flame retardancy according to
IEC 60332-1-2
▪ Up to 40 m, minimum cross-section 0.75 mm
cross-section necessary with increasing length.
Commercially available junction boxes can be used to connect CAN
bus lines of several RoCon devices.
Ensure that mains, sensor and data bus lines are routed separately.
Use only cable ducts with separators or separate cable ducts spaced
at least 2 cm apart. Line crossings are permissible.

A maximum of 16 devices with a total line length of up to 800 m can
be connected in the entire RoCon system.
EHS157034 room controller
A separate EHS157034 room controller can be connected for each
heating circuit to enable remote adjustment of operating modes and
target room temperatures from another room.
EHS157068 mixer module
The EHS157068 mixer module can be connected to the indoor unit
(J13 PCB connector) and is controlled by the electronic controller.
EHS157056 Internet gateway
The controller can be connected to the internet with the optional
EHS157056 gateway. This enables remote control of the indoor unit
by mobile phones (by app).
