Please follow these safety instructions closely to prevent accidents and mate-rial losses.

Safety instructions explained

DangerThis symbol warns against therisk of injury.

! 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

! Please noteRepairing components that fulfil asafety function can compromisethe safe operation of your heatingsystem.Replace faulty components onlywith original Viessmann spareparts.

DangerSubject to system configuration,DHW temperatures above 60 °Ccan occur. DHW with tempera-tures in excess of 60 °C can resultin 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 is stopped inaccordance with the following criteria:■ The actual temperature falls below the

shutdown temperature differentialDT A.

■ Exceeding the electronic temperaturelimit (max. 90°C) of control unit eZ

■ Reaching the temperature selected athigh limit safety cut-out qW (if installed)

Auxiliary function for DHW heating

The requirements for the auxiliary 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.

The system provides central heating ifthe 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 pumpin the Vitodens are started.

Installation

The circulation pump with connectingcable is part of the Solar-Divicon pumpstation.

Separate installation and serviceinstructions

Alternative pumps must be type-testedand installed in accordance with themanufacturer's details.

Connection

3-core cable with a cross-section of0.75 mm2.Rated current: 0.8 A

NotePumps that draw more than 190 W mustbe connected via an additional relay(coupler relay). Disable the speed con-trol for this pump (see chapter "Speedcontrol").

Speed control

Speed control is disabled at the factory("RPM" set to 0, see page 45). It canonly be enabled for relay output R1(solar circuit pump).The solar circuit pump should not haveits own 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" has been exceeded.If the temperature differential rises to"DT S" (differential temperature for thestart of the speed control), then thespeed is increased by 10% with everyrise by the value selected in "ANS"(rise).
