General safety instructions All electrical connections and safetymeasures have to be carried out by aspecialist according to the valid normsand VDE-guidelines as well as the localinstructions.

The electrical connection must be fix (seeinstructions by VDE 0100).

The electrical connection has to be doneaccording to the wiring diagram of therespective boiler control panel.

Important! Switch off plant completely before opening boiler control panel. Do not plug or unplug electrical connectors under voltage. This may cause a defect to the control or a dangerous electrical shock.

Safety measures for EMC - conform installation 1. Cables with mains voltage must be

generally installed separately fromsensor and data bus cables. In thiscase a minimum distance of 2 cm mustbe observed. Crossing of lines ispermitted.

2. Controls with own mains connectionrequire a separate installation of mainsand sensor or data bus cable. Whenusing cable ducts such with internalseparators are recommended.

3. Installing control or remote units closeto other components with electromagnetic emission such as solid staterelays, motors, transformers, dimmers,micro wave ovens, TV-sets, loud-speakers, computers, radio telephonesetc. a minimum distance of 40 cmmust be observed.

4. Between remote units and standardunit a minimum distance of 40 cm hasto be observed. Several standard unitsmay be installed side by side.

5. The mains connection of the heatingplant (standard unit or boiler controlpanel) must be carried out as anindependent electric circuit. It is notpermitted to install fluorescent tubes orother machines that could produceinterferences to the same electricalcircuit.

Remote unit RS

Mounting location

a – for applications without room sensorWithout room sensor function theremote unit may be fixed at any placein the interior range.

b – for applications with room sensorThe remote unit should be fixed at aheight of approx.1.20 – 1.50 m at aplace most representative of all rooms.It is recommended to chose an interiorwall of the coolest day room (such asentrance halls). In order to ensuresufficient air circulation at the roomstation, it must be mounted to the wallwith a gap inbetween.

The remote unit must not be mounted

– at locations exposed to direct sunlight(seasonal variations should be takeninto account)

– close to heat-producing appliances(televisions, refrigerators, wall lamps,radiators etc.)

– onto walls heated by under plasterheating pipes or chimneys.

– onto outside walls

– in corners behind curtains or shelves(due to insufficient ventilation)

– close to doors of unheated rooms (dueto the influence of low temperature)

– on unsealed under-plaster wiringboxes (influence of external lowtemperatures due to the chimneyeffect of installation tubes)

– in rooms with radiators controlled bythermostatic valves (mutual influence).

Mounting After removing the front panel by pressingthe locating lug at the lower side thesocket can be mounted at the desiredlocation using the enclosed dowel pinsand screws. The cable for the busconnection has to be led through the lowercut-out of the socket.Recommended connecting cable:

Terminal assignment The wiring between remote unit andstandard unit or boiler control panel has tobe made by a shielded data bus cable atterminals A and B of both units. Theconnecting terminals may not be changed and have to be installedaccording to the labelling of the terminalsA/B in the wall socket. Changing theterminals causes no displaying.

Socket (unit removed)

After completing the electrical wiring hangremote unit conclusively on top sideaccording figure on page 11 and turndown until it clicks into the wall socket. Electrical connections (control unit) See installation instructions of control unit.

Data bus addressing In order to guarantee a selectivecommunication between remote units andcontrol units it is necessary to set everyremote unit in the bi-directional data bussystem to the corresponding data busaddress.

This concerns in the same way thecoupling of control units for extension ofheating circuits, which communicate onthe same data bus line.

By this reason control units and remoteunits are equipped with data bus addresses.

Data bus address (control unit)

Single control units must always have theaddress 10. In heating plants with severalcontrol units (maximum 5) the maincontroller that works on the burner getsthe data bus address 10, the remainingcontrollers have to be set to addresses 20,30, 40 and 50 one after the next.

Adjustment of data bus address of the control unit To adjust the data bus address in thecontrol unit the corresponding specialistcode must be entered in the data bus levelfirst (see starting up the control unit).

Adjustment of data bus address of the remote unit

The assignment between the data busaddresses of the control units and remoteunits is to a fixed factory preset scheme inaccordance with the following table:

Automatic SET-Function This function allows to remove heating orhot water circuits from operation.

The control circuits are registratedautomatically, if their correspondingsensors are connected and provideacceptable measuring values. Controlcircuits without the corresponding sensorsremain automatically withoutconsideration.

The automatic set function will beactivated after every switch-on.

Automatical activation

Provided that the auto-set function isturned on (see SYSTEM-Level –parameter 14) and the initial start-up datewas not yet stored, connected ordisconnected sensors will be registeredautomatically at every switch-on of thecontrol unit. During this time errormessages of sensors (short circuit orinterruption) will be suppressed.

After the initial start-up date was stored, amodified sensor configuration can only betaken over by manual activation.

Manual activation

The auto-set function can be activated tooat any time manually by keeping the rotaryknob pressed when switching the unit on,until the auto set function is accepted inthe display.

The auto set function registers thefollowing sensors:– Outdoor sensor– Flow sensor 1– Flow sensor 2– Hot water tank sensor– Heat generator /boiler sensor

Furthermore the auto set function iscarried out only, if the control circuitswhich are assigned to the correspondingsensors were parameterised in therespective levels.

For the hot water sensor: HYDRAULIC Level

Parameter 2 - Function DHW charging pumpSetting range OFF or 1 (DHW chargingpump)

For the supply sensor 1: HYDRAULIC Level

Parameter 3 - Function mix. heating circuit 1Setting range OFF or 3 (mix. heatingcircuit)

For the supply sensor 2: HYDRAULIC Level

Parameter 4 - Function mix. heating circuit 2Setting range OFF or 3 (mix. heatingcircuit)

For the boiler sensor: Level HEAT GENERATOR Parameter 1 – Type of heat generatorSetting range OFF or 1 (1-stage-burner)

With that a programmed parameterisationwill not be changed again, the currentvalues will be checked before. Amodification is carried out only if one ofthe adjustments listed above is given. Inthis way the auto set function for examplenever can cancel a return flow increase ofmixer heating circuit 2, or can function it toa mixer heating circuit.

Malfunction messages In order to set up a precise diagnosis inthe case of malfunction the control systemis equipped with an extensive malfunctionmessage system. An occurring error isalways announced in the display of thecorresponding basic control and stored.

There are five different categories ofmalfunction messages:

1 - Sensor alarm messages Sensor values which are not in theirrespective measuring range will either besensor breaks or sensor short circuits.They appear with an error messageaccording to their use.

2 - Boiler alarm messages This messages depend on the actualswitching conditions. They appear with thecorresponding error message, dependingon the version and allocation.

3 - Logical alarm messages These messages will react on the actualcontrol result. They appear with thecorresponding error message, dependingon the version and allocation.

4 - Bus alarm messages These messages display addressproblems such as double addresses or notrecognizing addresses within the data bussystem. They appear with thecorresponding error message, dependingon the version and allocation.

5 - Alarm messages from boiler control (high efficiency condensing boilers)These fault messages come of the boilercontrol and are divided into permanentfaults (permanent lock) with error code E-XX (MCBA-code) or temporary faults (selfcancelling lock) with error code B-XX(MCBA-code).

The displaying characters and furtherprocessing of the logical faults can beenabled or suppressed by acorresponding parameterization (seeSYSTEM level-parameter 13 (logical errormessage).

Further processing in case of malfunction messages: – Alarms will be indicated in the basic display

of the control unit

– System errors appear in the informationlevel beside the corresponding information

– Malfunction messages are loaded into amalfunction message log (see descriptionbelow)

– Malfunction messages activate in case ofcorresponding parameterisation an alarmoutput for optical or audible signallers.

– Malfunction messages are transmitted viadata bus to corresponding gateways.

Malfunction log

The control unit has a malfunction log inwhich a maximum of five malfunctionmessages can be saved. The malfunctionmessages are displayed with date, timeand malfunction type (error number). Thequery is carried out in the sequence of theentered malfunction messages in the levelALARM.

The last (= most recent) malfunctionmessage is in first position (No. 01); theprevious malfunction messages areshifted down by a position upon each newmalfunction message. The fifthmalfunction message is deleted when anew message appears.

Malfunction messages from condensing boiler controls (MCBA) represent a specialfeature. They will not be stored into theinternal malfunction log because they areexternal errors.
