Safety instructions
Please follow these safety instructions closely to prevent accidents and material losses.
Work on the equipment
Installation, initial start−up,
maintenance and repairs must only
be carried out by a competent
person (heating engineer/
installation contractor) (EN50110,
part1, and VDE1000, part10 or local
regulations).
Before working on the equipment/
heating system, isolate the mains
electrical supply (e.g. by removing a
separate mains fuse or by means of
a mains electrical isolator) and
safeguard against unauthorised
re−connection.
Disconnect the system from the
mains electrical power by means of a
device which simultaneously isolates
all non−earthed conductors with at
least 3 mm contact separation.
When using gas as fuel, also close
the mains gas shut−off valve and
safeguard against unauthorised
re−opening.
Work requiring the control unit to be
opened must not subject internal
components to electrostatic
discharges.
Work on gas equipment
This must only be carried out by an
approved installer.
Observe all commissioning work for
gas installations specified by
TRGI’86/96 or TRF1996 or local
regulations.
Repairs

repairs on components that fulfil a
safety function.
Use only original Viessmann spare
parts or equivalent, which have been
approved by Viessmann.

engineer designated by him; all
actual values should be recorded in a
