Safety instructions
Safety instructions
Please follow these safety instructions closely to prevent accidents and
material losses.
Safety regulations
Installation, initial start-up, inspection,
maintenance and repairs must only
be carried out by a competent
person (heating engineer/installation
contractor).
Observe all current safety regulations
as defined by DIN, EN, DVGW and
VDE or locally applicable standards.
See also the safety instructions sheet
in the Vitotec technical documentation
folder.
efore working on the equipment/
heating system/solar heating system,
isolate its mains electrical supply
(e.g. by removing a separate mains
fuse or by means of a mains
electrical isolator) and safeguard
against unauthorised reconnection.
Earthing/lightning protection of the
solar heating system
Install an electrical conductor on the
pipework system of the solar circuit
in the lower part of the building in
accordance with VDE or local
regulations.
The connection of the collector
system to an existing or new
lightning conductor system or the
creation of local earth bonding must
only be carried out by authorised
trained personnel under observation
of local conditions.
Repair work
It is not permitted to carry out
repairs on parts that fulfil a safety
function.
Use only original Viessmann spare
parts, or equivalent parts that have
been approved by Viessmann.
Initial start up
The initial start-up must be carried
out by the system installer or a
designated commissioning engineer.
All actual values should be recorded
in a commissioning/service report.
Instructing the system user
The system installer must hand the
operating instructions to the system
user and instruct him/her in the
operation of the system.

System design
Dual mode DHW heating with VitocellĆBĂ100 or VitocellĆBĂ300
DHW heating without solar energy
The upper indirect coil of the DHW
cylinder is heated by a boiler. The
cylinder thermostat with cylinder
temperature sensorĂ6 of the boiler
control unit switches cylinder
loading pumpĂ7Ă.
DHW with solar energy
When a temperature difference
higher than the start-up temperature
differentialĂDO set in control unitĂ1
is measured between collector
temperature sensorĂ2 and cylinder
temperature sensorĂ3, solar circuit
pumpĂ4 is switched ON and the
DHW cylinder is heated up. The pump
will be switched OFF if the actual
temperature falls below shutdown
temperature differentialĂDF.
The temperature in the DHW cylinder
is limited by the electronic
temperature limiter (safety shutdown
at 90ĂºC) in control unitĂ1 or by high
limit safety cut-outĂ5 (if required).
When the preset temperature is
exceeded, these devices switch OFF
solar circuit pumpĂ4.
The pasteurisation requirements are
met by circulation pumpĂ8 and
sufficient heat input. Circulation
(relayering) starts if 60ĂºC is not
reached inside the DHW cylinder.
ĂSafety instructions
With temperatures higher than 60 ºC,
limit the HW temperature to 60 ºC
by installing a mixing device, e.g. a
thermostatic mixing valve ( HW
cylinder accessory). The mixing
equipment does not prevent the risk
of scalding at the tap. The
installation of a mixer tap at the
draw-off point is required.
