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

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.

Vitodens – DHW heating and central heating backup with a multi-
mode heating water buffer cylinder
Main components
■ Viessmann solar collectors
■ Vitocell 340-M or Vitocell 360-M multi-
mode heating water buffer cylinder
with integral DHW heating, with or
without stratification system
■ Vitosolic 100, type SD1
■ Solar-Divicon
■ Wall mounted gas boiler from the year
of manufacture 2008
– Vitodens 200-W, type WB2B
– Vitodens 300-W, type WB3C
Function description
DHW heating with solar energy
Solar circuit pump R1 eE starts and
heating water buffer cylinder qP is
heated up if the temperature 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)
Entire heating water buffer cylinder qP is
heated by the solar thermal system if the
insolation is adequate.
The upper part of heating water buffer
cylinder qP will only be reheated by
boiler 1 if the actual water temperature
falls below the set temperature selected
at boiler control unit 2.
If the solar energy is inadequate to cover
the entire heating demand, the DHW in
the lower part of heating water buffer cyl-
inder qP will be preheated by solar
energy. The DHW in the upper part of the
cylinder is heated to the required tem-
perature by boiler 1.
The burner is started and three-way
diverter valve rZ is switched to position
"AB-A" via cylinder temperature sen-
sor qZ of the boiler control unit. When
the set DHW temperature has been
reached, the burner is stopped and
three-way diverter valve rZ is switched
to position "AB-B".
Suppression of DHW cylinder reheat-
ing by the boiler
Coding address "67" in boiler control
unit 2 defaults a third set DHW tem-
perature (setting range 10 to 95 °C). This
value must be below the first set DHW
temperature. Heating water buffer cylin-
der qP is only heated by boiler 1 (solar
circuit pump R1 eE runs) if this set value
cannot be achieved by the solar thermal
system.

DHW heating without solar energy
The upper area of heating water buffer
cylinderqP is heated by boiler 1. The
integral instantaneous water heater/
standby section is heated by the sur-
rounding buffer cylinder water.
The cylinder thermostat with cylinder
temperature sensor qZ of boiler control
unit 2 controls
three-way diverter valve rZ.
Central heating with solar energy
The system provides central heating if
the temperature at sensor qT is ade-
quate.
Central heating without solar energy
If the temperature at sensor qT is inad-
equate, the burner and circulation pump
in the Vitodens are started. The area
between HV2/HR1 and HR2 in heating
water buffer cylinder qP is heated up to
the set temperature for the heating cir-
cuits in weather-compensated mode.
When this set temperature is exceeded,
the burner and, after a delay, the circu-
lation pump in the Vitodens are stop-
ped.

Vitodens – DHW heating with freshwater module and central
heating backup with heating water buffer cylinder
Main components
■ Viessmann solar collectors
■ Freshwater module
■ Heating water buffer cylinder
Vitocell140-E or Vitocell 160-E
■ Vitosolic 100, type SD1
■ Solar-Divicon
■ Wall mounted gas boiler from the year
of manufacture 2008
– Vitodens 200-W, type WB2B
– Vitodens 300-W, type WB3C
Function description
Freshwater module qP heats DHW
when hot water is drawn. The energy
supply to freshwater module qP is pro-
vided via heating water buffer cylin-
der rP.
DHW heating with solar energy
Solar circuit pump R1 eE starts and
heating water buffer cylinder rP is
heated up if the temperature differential
between collector temperature sensor
S1 eQ and cylinder temperature sensor
S2 rQ exceeds the start temperature dif-
ferential 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 rR (if installed)
Entire heating water buffer cylinder rP is
heated by the solar thermal system if the
insolation is adequate.
The upper part of heating water buffer
cylinder rP will only be reheated by
boiler 1 if the actual water temperature
falls below the set temperature selected
at boiler control unit 2.
The burner is started and three-way
diverter valve rZ is switched to position
"AB-A" via cylinder temperature sen-
sor rW of the boiler control unit. When
the set DHW temperature has been
reached, the burner is stopped and
three-way diverter valve rZ is switched
to position "AB-B".
Suppression of DHW cylinder reheat-
ing by the boiler
Coding address "67" in boiler control
unit 2 defaults a third set DHW tem-
perature (setting range 10 to 95 °C). This
value must be below the first set DHW
temperature. Heating water buffer cylin-
der rP is only heated by the boiler (solar
circuit pump R1 eE runs) if this set value
cannot be achieved by the solar thermal
system.
DHW heating without solar energy
The upper area of heating water buffer
cylinder rP is heated by boiler 1.
The cylinder thermostat with cylinder
temperature sensor rW of boiler control
unit 2 controls
three-way diverter valve rZ.

Central heating with solar energy
Central heating is provided via heating
water buffer cylinder rP if the tempera-
ture at sensor rE is adequate.
Central heating without solar energy
If the temperature at sensor rE is inad-
equate, the burner and circulation pump
in the Vitodens are started. The area
between HV3/HR1 and HR3 in heating
water buffer cylinder rP is heated up to
the set temperature for the heating cir-
cuits in weather-compensated mode.
