! Please noteThis symbol warns against therisk of material losses and envi-ronmental pollution.

NoteDetails identified by the word "Note" con-tain additional information.

Target group

These instructions are exclusivelydesigned for qualified personnel.■ Work on electrical equipment must

only be carried out by a qualified elec-trician.

■ The system must be commissioned bythe system installer or a qualified per-son authorised by the installer.

Regulations

Observe the following when working onthis 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 andall 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 bymeans of a main isolator.

■ Safeguard the system against unau-thorised reconnection.

! Please noteElectronic modules can be dam-aged by electrostatic dis-charges.Touch earthed objects, such asheating or water pipes, to dis-charge static loads.

Repair work

DangerSubject to system configuration,DHW temperatures above 60 °Ccan occur. DHW with tempera-tures in excess of 60 °C cancause scalding.

To limit the temperature to 60 °C,install mixing equipment, e.g. athermostatically controlled mix-ing valve (accessory). Install amixer tap as anti-scalding deviceat the draw-off point.

Function description

DHW heating with solar energy

Solar circuit pump R1 eE starts andDHW cylinder qP is heated up if the tem-perature differential between collectortemperature sensor S1 eQ and cylindertemperature sensor S2 qQ exceeds thestarting temperature differential DT E.Solar circuit pump R1 eE stops if:■ The actual temperature falls below the

stop temperature differential DT A■ The electronic temperature limit of

control unit eZ is exceeded (max.90 °C)

■ The temperature selected at high limitsafety cut-out qW (if installed) isreached

Additional function for DHW heating

The requirements for the additional func-tion are achieved through circulationpump R2 qT.

Suppression of DHW cylinder reheat-ing by the boiler

Coding address "67" in boiler control unit2 defaults a third set DHW temperature(setting range 10 to 95 °C). This valuemust be below the first set DHW temper-ature. DHW cylinder qP will only beheated by boiler 1 (solar circuitpump R1 eE runs) if this set value cannotbe achieved by the solar thermal sys-tem.

DHW heating without solar energy

The upper section of DHW cylinder qP isheated by boiler 1. The cylinder ther-mostat with cylinder temperature sen-sor 3 of boiler control unit 2 regulatescylinder heating 4.

Entire heating water buffer cylinder qP isheated by the solar thermal system if theinsolation is adequate.

The upper part of heating water buffercylinder qP will only be reheated byboiler 1 if the actual water temperaturefalls below the set temperature selectedat boiler control unit 2.If the solar energy is inadequate to coverthe entire heating demand, the DHW inthe lower part of heating water buffer cyl-inder qP will be preheated by solarenergy. The DHW in the upper part of thecylinder is heated to the required tem-perature by boiler 1.The burner starts and three-way divertervalve rZ switches to position "AB-A" viacylinder temperature sensor qZ of theboiler control unit. When the set DHWtemperature has been reached, theburner stops and three-way divertervalve rZ switches to position "AB-B".


Coding address "67" in boiler controlunit 2 defaults a third set DHW tem-perature (setting range 10 to 95 °C). Thisvalue must be below the first set DHWtemperature.

Vitodens – DHW heating with freshwater module and centralheating backup with heating water buffer cylinder

of manufacture 2008– Vitodens 200-W, type WB2B– Vitodens 300-W, type WB3C


Freshwater module qP heats DHWwhen hot water is drawn. The energysupply to freshwater module qP is pro-vided via heating water buffer cylin-der rP. Buffer cylinder rP is heated bythe solar thermal system or, in the upperarea, by boiler 1.The heated DHW is heated by freshwa-ter module qP according to the instanta-neous water heater principle. An internalpump transports the heating water fromheating water buffer cylinder rP into thefreshwater module qP. This heats theDHW in the heat exchanger of the fresh-water module qP according to the coun-tercurrent principle. The freshwatermodule qP is regulated by its internalcontrol unit.

When utilising the freshwater modulewith integral DHW circulation pump, thethree-way diverter valve qQ in conjunc-tion with sensors S3 qE and S4 qW of thefreshwater module qP can be regulatedby its control unit to provide an optimumstratification of the return water into theheating water buffer cylinder rP.


Solar circuit pump R1 eE starts andheating water buffer cylinder rP isheated up if the temperature differentialbetween collector temperature sensorS1 eQ and cylinder temperature sensorS2 rQ exceeds the start temperature dif-ferential DT E.Solar circuit pump R1 eE stops if:■ The actual temperature falls below the



■ The temperature selected at high limitsafety cut-out rR (if installed) isreached

Entire heating water buffer cylinderrP isheated by the solar thermal system if theinsolation is adequate.The upper part of heating water buffercylinder rP will only be reheated byboiler 1 if the actual water temperaturefalls below the set temperature selectedat boiler control unit 2.

1. Set "OWMZ" to "ON" (seepage 43).

2. Check the throughput at the flowmeter of the Solar-Divicon at 100 %speed and set that value as"VMAX".

3. Adjusting the frost protection of theheat transfer medium "MEDT".

4. If necessary, adjust the mixing ratioof the heat transfer medium "MED%".

Speed control

Speed control is disabled at the factory("RPM" set to 0, see page 33). It canonly be enabled for relay output R1(solar circuit pump).The solar circuit pump must not have itsown speed control. Set multi-stagepumps to the required stage.

NoteWhen using pumps with their own varia-ble speed control, set "RPM" to 0.

The solar circuit pump will be switchedon, if "DT E" is exceeded.If the temperature differential rises to"DT S" (differential temperature for thestart of the speed control), the speed isincreased by 10% with every rise by thevalue selected in "ANS" (rise).
