Set-up and installation
4.5.12 Connecting a ROTEX room thermostat
4.5.13 Connecting optional ROTEX RoCon system
components
The optional RoCon devices must be connected to the ROTEX
HPSU monobloc compact via a 4-wire CAN bus line (connection
J13).
For this, ROTEX recommends shielded lines with the following
characteristics:
–
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
2
. Larger con-
ductor 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 sepa-
rately. 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.
ROTEX RoCon U1 room station
A separate RoCon U1 room station can be connected for each
heating circuit to enable remote adjustment of operating modes
and target room temperatures from another room.
ROTEX RoCon M1 mixer module
It is possible for the ROTEX HPSU monobloc compact to be con-
nected to the RoCon M1 mixer module, which is operated using
the RoCon mb electronic controller.
The connection of the CAN data bus lines is identical to fig. 4-38
at connection J13 of the ROTEX HPSU monobloc compact.
A separate manual containing instructions about instal-
lation and operation is included with this component.
