Intended use presupposes that a fixed installation in
conjunction with permissible, system-specific compo-
nents has been carried out.
Commercial or industrial usage for a purpose other
than central heating or DHW heating shall be deemed
inappropriate.
Any usage beyond this must be approved by the man-
ufacturer in each individual case.
Incorrect usage or operation of the appliance (e.g. the
appliance being opened by the system user) is prohibi-
ted and will result in an exclusion of liability. Incorrect
usage also occurs if the components in the heating
system are modified from their intended function.
Note
This appliance is intended exclusively for domestic
use. Untrained persons can also operate this appli-
ance safely.
Commissioning
Your heating contractor must carry out the commis-
sioning and matching of the control unit to local and
structural conditions and must also provide training in
system operation.
The Vitotrol 350 can control up to 20 different circuits.
At the factory these circuits are each designated as a
"Regulated circuit"
. We recommend you rename
these circuits during commissioning to suit local condi-
tions.
Note
These operating instructions also describe functions
that are only available for certain boilers or together
with accessories. These functions are not specifically
identified.
Check with your heating contractor should you have
any questions relating to the available range of func-
tions and accessories for both your boiler and your
heating system.
Permissible ambient temperature
Incorrect ambient conditions can result in damage to
the control unit and put safe operation at risk.
Observe the installation and service instructions
of the control unit.
Permissible ambient temperature for the Vitotrol 350:
■
Storage: -25 °C to 60 °C
■
Operation: 0 °C to 40 °C
Energy saving tips
Use the adjustment options offered by your boiler con-
trol unit:
■
For central heating, select the operating program
that meets your current requirements:
–
For brief periods of absence (a few hours shopping
for example), select
"Economy mode"
.
As long as economy mode is activated, the room
temperature is reduced.
–
If you are away for longer periods, select
"Holiday
program"
.
Central heating will be automatically switched off
for as long as the holiday program remains active.
–
If you have no need to heat your home or provide
DHW for longer periods of time, switch off heating
mode for the respective heating circuits as well as
DHW mode.
■
Never set the temperature inside the DHW cylinder
too high.
