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 at temperatures
above 60 ºC causes scalding.
To limit the temperature to 60 ºC,
install mixing equipment, e.g. a
thermostatically controlled mix-
ing valve (accessories). Install a
mixer tap as anti-scalding device
at the draw-off point.
System example
DHW heating with dual mode DHW cylinder
Main components
■ Viessmann solar collectors
■ DHW cylinder Vitocell 100-U, type
CVUA
■ Vitosolic 100, type SD1
■ Solar-Divicon (integrated into Vitocell
100-U, type CVUA)
■ Wall mounted or floorstanding oil/gas
boiler
Function description
DHW heating with solar energy
If the temperature differential between
collector temperature sensor S1 eQ and
cylinder temperature sensor S2 qQ is
greater than the start temperature differ-
ential DT E, solar circuit pump R1 eE
starts and DHW cylinder qP is heated.
Solar circuit pump R1 eE stops in
accordance with the following criteria:
■ The actual temperature falls below the
stop temperature differential DT A
■ The electronic temperature limit (up to
90 °C) set in control unit eZ is excee-
ded
■ The temperature selected at high limit
safety cut-out qW (if installed) is
reached
Additional 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 specifies a third set DHW tempera-
ture (setting range 10 to 95 ºC). This
value must be below the first set DHW
temperature. DHW cylinder qP is only
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 top section of DHW cylinder qP is
heated by boiler 1. The cylinder tem-
perature controller with cylinder temper-
ature sensor 3 of boiler control unit
2 regulates cylinder heating 4.

Note
"DT E" can be set at least 0.5 K higher
than "DT A" and up to 0.5 K lower than
"DT S" (see page 29).
"DT A" can be set up to 0.5 K below
"DT E".
Information regarding speed control
of the solar circuit pump
