eneral information
Safety instructions
Please follow these safety instructions closely to prevent accidents and
material losses.
Safety regulations
Installation, commissioning,
inspection, maintenance and
repairs must only be carried
out by a competent person
(heating engineer/refrigeration
specialist/installation contractor).
Observe all current safety
regulations as defined by DIN,
DINĂEN, DV W and VDE (or local
regulations).
See also the safety instructions sheet
in the Vitotec Technical uide folder.
Before 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, to
comply with VDE or local regulations.
Connection of the collector system to
a new or existing lightning protection
facility or the provision of local
earthing should only be carried out
by authorised personnel, who must
take into account the conditions
applicable on site.
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.
Commissioning
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.
¨ĂSafety instruction
In this instruction manual, this
heading denotes information which
must be observed to prevent
accidents and material losses.

General notes
Over the following pages, the
methods of operation have been
described, and the installation has
been depicted as different schemes.
A summary is provided which lists
essential control equipment.
The temperatures stated are guide
values; other values may be set to
meet particular requirements.
The circulation pumps referred to in
the examples (contained in
Solar-Divicon) are AC pumps.
A itional DHW heating function
According to DV WĂWĂ551/WĂ552,
systems with larger cylinder capacity
than 400Ălitres (incl. the solar
preheating stage) should be
pasteurised daily, i.e. the entire
water content must be heated to
60ĂºC once each day.
To meet this requirement, we
recommend that the system is
heated up, preferably late afternoon,
to ensure that the lower part of the
cylinder or the preheating stage is
cold again following the expected
hot water consumption (in the
evening and the following morning)
and can, therefore, be heated up
again by solar energy.
ĂSafety instructions
With temperatures higher than 60 º,
DHW temperature must be limited to
60 º by installing a mixing device,
e.g. a thermostatic mixing valve
(DHW 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.

(safety shutdown at 90 ºC) set at
the control unit or that set at the
high limit safety cut-out (if
required) is exceeded.
The additional function requirements
(see page 5) are met by circulation
pump 8.
Central heating without solar energy
Diverter valve qW remains at zero
volts (setting "AB-B") if the
differential temperature between
calorifier temperature sensor qP and
central heating return temperature
sensor 9 falls below shutdown
temperature differential DT6off. No
flow through the heating water
calorifier takes place.
The boiler provides heat to the
heating circuit according to the
heating curve set at the boiler
control unit.
Central heating with solar energy
Circulation pumpĂqE for heating heat
exchanger qT is switched ON if the
DHW cylinder cannot be heated and
a temperature differential higher
than start-up temperature differential
DT2on is measured between collector
temperature sensor 2 and calorifier
temperature sensor qQ. If the actual
temperature falls below shutdown
temperature DT2off or when
maximum temperature Tcyl2max has
been reached, it is switched OFF.
Calorifier loading pump qR is
switched ON and the calorifier is
heated, if a temperature differential
higher than start-up temperature
differential DT5on is measured
between temperature sensor qZ
(heat exchanger) and calorifier
temperature sensor qQ.

The pump will be switched OFF if the
actual temperature falls below
shutdown temperature differential
DT5off.
The temperature in the calorifier is
limited by the electronic temperature
limiter (safety shutdown at 90ĂºC) or
by the high limit safety cut-out (if
required). It will switch calorifier
loading pump qE OFF if the set
temperature is exceeded.
Circulation pump qE is switched OFF
for approx. 2 minutes, roughly every
15 minutes (values t stop and t circ
adjustable, see page 16), to check
whether the temperature at the
collector temperature sensor is high
enough to change over to DHW
cylinder heating. If, during this time,
DTon is exceeded, the DHW cylinder
continues to be heated.
Diverter valve qW is set to "AB-A" if
the differential temperature between
calorifier temperature sensor qP and
heating return temperature sensor 9
exceeds start-up temperature
differential DT6on; the heating return
water will be routed to the boiler via
the calorifier. If the temperature of
the preheated return water is
insufficient, the boiler reheats the
water to the necessary flow
temperature level.
If the actual temperature falls below
shutdown temperature differential
DT6off, the diverter valve will be set
to "AB-B".
