Safety instructions explained
Danger
This symbol warns against the
risk of injury.
!Please note
This symbol warns against the
risk of material losses and envi-
ronmental pollution.
Note
Details identified by the word "Note" con-
tain additional information.
Target group
These instructions are exclusively
designed for qualified personnel.
■ Work on electrical equipment must
only be carried out by a qualified elec-
trician.
■ The system must be commissioned by
the system installer or a qualified per-
son authorised by the installer.
Regulations
Observe the following when working on
this system
■ all legal instructions regarding the pre-
vention of accidents,
■ all legal instructions regarding envi-
ronmental protection,
■ the Code of Practice of relevant trade
associations.
■ all current safety regulations as
defined by DIN, EN, DVGW, VDE and
all locally applicable standards
Working on the system
■ Isolate the system from the power sup-
ply and check that it is no longer 'live',
e.g. by removing a separate fuse or by
means of a main isolator.
■ Safeguard the system against unau-
thorised reconnection.
!Please note
Electronic modules can be dam-
aged by electrostatic dis-
charges.
Touch earthed objects, such as
heating or water pipes, to dis-
charge static loads.
Repair work
!Please note
Repairing components that fulfil a
safety function can compromise
the safe operation of your heating
system.
Replace faulty components only
with original Viessmann spare
parts.

Ancillary components, spare and
wearing parts
!Please note
Spare and wearing parts that
have not been tested together
with the heating system can com-
promise its function. Installing
non-authorised components and
non-approved modifications or
conversions can compromise
safety and may invalidate our
warranty.
For replacements, use only orig-
inal spare parts supplied or
approved by Viessmann.

Danger
Subject to system configuration,
DHW temperatures above 60 °C
can occur. DHW with tempera-
tures in excess of 60 °C can result
in scalding.
To limit the temperature to 60 °C,
install mixing equipment, e.g. a
thermostatically controlled mix-
ing valve (accessory). Install a
mixer tap as anti-scalding device
at the draw-off point.
System example 1
DHW heating with dual-mode DHW cylinder
Main components
■ Viessmann solar collectors
■ DHW cylinders Vitocell 100-B or
Vitocell 300-B
■ Vitosolic 100, type SD1
■ Solar-Divicon
■ Wall mounted oil/gas boiler or oil/gas
boiler
Function description
DHW heating with solar energy
Solar circuit pump R1 eE starts and
DHW cylinder qP is heated up if the tem-
perature differential between collector
temperature sensor S1 eQ and cylinder
temperature sensor S2 qQ exceeds the
starting temperature differential DT E.
Solar circuit pump R1 eE is stopped in
accordance with the following criteria:
■ The actual temperature falls below the
shutdown temperature differential
DT A.
■ Exceeding the electronic temperature
limit (max. 90°C) of control unit eZ
■ Reaching the temperature selected at
high limit safety cut-out qW (if installed)
Auxiliary function for DHW heating
The requirements for the auxiliary func-
tion are achieved through circulation
pump R2 qT.
Suppression of DHW cylinder reheat-
ing by the boiler
Coding address "67" in boiler control unit
2 defaults a third set DHW temperature
(setting range 10 to 95 °C). This value
must be below the first set DHW temper-
ature. DHW cylinder qP will only be
heated by boiler 1 (solar circuit
pump R1 eE runs) if this set value cannot
be achieved by the solar thermal sys-
tem.
DHW heating without solar energy
The upper section of DHW cylinder qP is
heated by boiler 1. The cylinder ther-
mostat with cylinder temperature sen-
sor 3 of boiler control unit 2 regulates
cylinder heating.
