The set cylinder temperature (set DHW temperature) is
set too low.
Inform your local heating contractor.
The solar circuit pump is faulty. Inform your local heating contractor.

DHW cylinder (if installed)
Standards DIN 1988-8 and EN 806 specify that main-
tenance and cleaning should be carried out no later
than 2 years after commissioning and as required
thereafter.
Only a qualified heating contractor should clean the
inside of a DHW cylinder and the DHW connections.
If any water treatment equipment (e.g. a sluice or
injection system) is installed in the cold water supply of
the DHW cylinder, ensure this is refilled in good time.
In this connection, observe the manufacturer's instruc-
tions.
In addition for Vitocell 100:
We recommend that the correct function of the sacrifi-
cial anode is checked annually by your heating con-
tractor.
The function of the sacrificial anode can be checked
without interrupting the system operation. The heating
contractor will check the earth current with an anode
tester.
Safety valve (DHW cylinder)
The function of the safety valve must be checked
every six months by the user or a contractor through
venting (see valve manufacturer's instructions). The
valve seat may become contaminated.
Water may drip from the safety valve during a heat-up
process. The outlet is open to the atmosphere and
must not be closed off.
Potable water filter (if installed)
To maintain high hygienic standards, proceed as fol-
lows:
■Replace filter element on non-back flushing filters
every six months (visual inspection every
two months).
■On back flushing filters, back flush every
two months.
Damaged cables / lines
If there is damage to the connecting cables or lines of
the appliance or externally installed accessories, these
must be replaced with special cables or lines. Only use
Viessmann cables / lines as replacement. For this,
notify your qualified contractor.
