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 use 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
use also occurs if the components in the heating sys-
tem are modified from their intended function.
Note
This appliance is intended exclusively for domestic
use. The appliance can also be operated safely by
untrained persons.
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
how to operate the system.
The Vitotrol 350-C can control up to 20 different cir-
cuits. At the factory these circuits are each designated
as a
"Regulated circuit"
. We recommend you
rename these circuits during commissioning to suit
local conditions.
Note
These operating instructions also describe functions
that are only available for certain boilers, or only in
conjunction with accessories. These functions are not
specifically identified.
For questions relating to the available range of func-
tions and accessories for your boiler and your heating
system, check with your heating contractor.
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 Vitotrol 350-C:
■
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,
for example when out shopping), select
"Economy
mode"
The room temperature is reduced for as long as
economy mode is active.
–
If you are going away for longer periods, select
"Holiday program"
.
Central heating is automatically switched off for as
long as the holiday program is active.
–
If you have no need to heat your home or provide
DHW for a prolonged period, switch off heating
operation for the respective heating circuits and
switch off DHW heating.
■
Do not set the temperature inside the DHW cylinder
too high.
