4.7.11 Connection of optional RoCon system
components
The optional RoCon devices must be connected to the Daikin
Altherma EHS(X/H) via a 4-wire CAN bus line (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.
