Safety instructions
Please follow these safety instructions closely to prevent accidents
and material losses.
Safety instructions explained
!Please note
This symbol warns against the
risk of material losses and envi-
ronmental pollution.
Note
Details identified by the word "Note"
contain additional information.
Installation, initial start-up, inspection,
maintenance and repairs must only be
carried out by a competent person
(heating engineer/installation contrac-
tor).
Before working on the equipment/heat-
ing system, isolate the power supply
(e.g. by removing a separate mains
fuse or by means of a mains isolator)
and safeguard against unauthorised
reconnection.
When using gas as fuel, also close the
main gas shut-off valve and safeguard
against unauthorised reopening.
Repairing components which fulfil a
safety function can compromise the
safe operation of your heating system.
For replacements, use only original
spare parts supplied or approved by
Viessmann.

Making the LON connection
The Viessmann LON is designed for
"line" bus topology with a terminator at
both ends (accessories).
The transfer distances for LON are sub-
ject to the electrical properties of the
relevant cable. For this reason, only
use the specified cable types. Use only
one cable type within each LON.
Cable types (on site):
■ 2-core cable, CAT5, screened
■ JY(St)Y 2 x 2 x 0.8 mm (telephone
cable)
Observe the requirements for cabling
and operation of the LON interface FTT
10-A.
All Viessmann appliances are connec-
ted with RJ45 connectors. The
Viessmann LON always requires cores
"1" and "2" plus the screen. The cores
are interchangeable.
Note
When connecting external switching
contacts and on-site components,
observe the insulation requirements of
IEC/EN 60335-1.
