Anti-scalding protection

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.

Equipotential bonding and lightning protection of the solar ther-mal system

Install an electrical conductor on thepipework system of the solar circuit in thelower part of the building in compliancewith VDE or local regulations.

The connection of the collector system toa new or existing lightning protectionsystem or the provision of local earthingmust only be carried out by authorisedtrained personnel, who must take intoaccount the conditions applicable onsite.

Additional function for DHW heating

DVGW W 551 specifies that the totalwater content is maintained at 60 ºC andthe pre-heat stages must be heated onceevery day to 60 ºC.■ Systems with a cylinder capacity, incl.

preheat stage, in excess of 400 litres■ Systems with a line content in excess

of 3 l from the DHW cylinder to thedraw-off point

We recommend heating up in late after-noon. This ensures that the lower cylin-der area or the pre-heating stage is coldagain following the expected drawings(evenings and the following morning)and can subsequently be heated upagain by solar energy.

NoteFor detached houses and two-familyhomes, this heat up is recommended,but not compulsory.

■ Actual temperature dropping belowthe stop temperature differential ΔToff

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

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


The requirements for the additional func-tion are achieved through circulationpump R5 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 regulatescirculation pump for cylinder heating4.

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. DHW cylinder qP will onlybe heated by boiler 1 (solar circuitpump R1 eE runs) if this set value cannotbe achieved by the solar thermal sys-tem.


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 regulatescirculation pump for cylinder heat-ing 4.

Central heating with solar energy

Circulation pump R4 eT is started to heatheating water buffer cylinder rP if theDHW cylinder qP cannot be heated andthe temperature differential between col-lector temperature sensor S1 eQ andbuffer cylinder temperature sensor S4rQ is greater than start temperature dif-ferential ΔT2on. The pump will stop if theactual temperature falls below the stoptemperature differential ΔT2off or it rea-ches the set buffer cylinder temperatureTcyl2set.The temperature inside heating waterbuffer cylinder rP will be limited by theelectronic temperature limiter or highlimit safety cut-out rR (if required).Circulation pump R4 eT is stoppedroughly every 15 min for approx. 2 min,(times adjustable), to check whether thetemperature at collector temperaturesensor S1 eQ is high enough to changeover to DHW cylinder heating qP.Three-way diverter valve R6 rZ isswitched to position "AB-A" and the heat-ing return water is routed to boiler 1 viaheating water buffer cylinder rP, if thetemperature differential between buffercylinder temperature sensor S5 rE andheating circuit return temperature sen-sor S6 rT exceeds start temperature dif-ferential ΔT6on. If the temperature of thepreheated return water is too low, boiler1 reheats the water to the required flowtemperature. Three-way diverter valveR6 rZ is switched to position "AB-B" ifthe actual temperature falls below thestop temperature differential ΔT6off.

Central heating without solar energy

Three-way diverter valve R6 rZ remainsat zero volt (position "AB-B") if the tem-perature differential between buffer cyl-inder temperature sensor S5 rE andheating circuit return temperature sensorS6 rT is less than temperature differen-tial ΔT6off. There will be no flow throughheating water buffer cylinder rP.

Boiler 1 supplies the heating circuitwith heat according to the heating curveset at boiler control unit 2.A low loss header 6 with flow temper-ature sensor 5 is required in conjunc-tion with a wall mounted oil/gasboiler.

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. This is regulated bythe internal control unit of the freshwatermodule qP.When utilising the freshwater modulewith integral DHW circulation pump, thethree-way diverter valve qQ in conjunc-tion with sensors qE and S4 qW of thefreshwater module can be regulated byits 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 is greater than the start tempera-ture differential ΔTon.Solar circuit pump R1 eE is stopped inaccordance with the following criteria:■ Actual temperature dropping below

The temperature inside heating waterbuffer cylinder rP will be limited by theelectronic temperature limiter or highlimit safety cut-out rR (if required).Circulation pump R4 eT is stoppedroughly every 15 min for approx. 2 min,(times adjustable), to check whether thetemperature at collector temperaturesensor S1 eQ is high enough to changeover to DHW cylinder heating qP.Three-way diverter valve R6 rZ isswitched to position "AB-A" and the heat-ing return water is routed to boiler 1 viaheating water buffer cylinder rP, if thetemperature differential between buffercylinder temperature sensor S5 rE andheating circuit return temperature sen-sor S6 rT exceeds temperature differ-ential ΔT6on. If the temperature of thepreheated return water is too low, boiler1 reheats the water to the required flowtemperature. Three-way diverter valveR6 rZ is switched to position "AB-B" ifthe actual temperature falls below thestop temperature differential ΔT6off.


Three-way diverter valve R6 rZ remainsat zero volt (position "AB-B") if the tem-perature differential between buffer cyl-inder temperature sensor S5 rE andheating circuit return temperature sensorS6 rT is less than temperature differen-tial ΔT6off. There will be no flow throughheating water buffer cylinder rP.Boiler 1 supplies the heating circuitwith heat according to the heating curveset at boiler control unit 2.

■ If the relays 3, 6 and 7 have not beenassigned by the scheme ("System"),they could, for example, be used forthe Function blocks 1 to 3 (see thetable for the respective system frompage 95).

■ Within a function block, there are 4functions that can be combined asrequired:– 2 thermostat functions– 1 temperature differential control– 1 time switch with three periods that

can be activated

■ In the delivered condition, certain sen-sors are assigned to these functions(Reference sensors). These sensorscan be switched, i.e. sensors alreadyused can be used for additional func-tions (see page 161).

■ Make all settings in menu "System"(see from page 158).

A relay assigned to a function block willonly switch if the conditions of all acti-vated functions are met. These func-tions act like individual switches in aserial circuit (see the following dia-gram).

Cyclical heating

■ If the consumer cannot be heated withpriority, the next consumer in line willbe heated for an adjustable cycle time"t-circ.".

■ After this time has expired, the solarcontrol unit checks the rise of the col-lector temperature during the cyclicalpause time "t-stop".If the value "ΔT Col" is reached, "t-stop" is set to zero and starts again.

■ As soon as the start conditions for theconsumer with priority have been met,that consumer will be heated again.Otherwise, the next-in-line consumerswill continue to be heated.

■ Once the consumer with priority hasreached its set temperature "Tcylset", it will no longer be taken into con-sideration for cyclical heating.
