The intelligent boiler managementcontroller for perfect operation ofheating and hot water systems.

TopTronic

For perfect control of heating and hot water systemsfor single and multiple boiler arrangements.

TopTronic

State-of-the-arttechnologyThe TopTronic control systembrings together Hoval'sconsiderable experience inthe field of heating & hotwater control, together with ahigh performance micro-processor controls package.

The result is a simple user-friendly operating platformthat controls individualheating and hot watersystems and optimisesenergy conservation.

Display showing date and time,boiler and DHW temperatures.

Flip down access cover forprogramming either manually or viaa PC link.

Adjustable setpoint for roomtemperature during night time/standby operation.

Multi-functional switch with 3individual time programmes, 3additional operating positions andpositions for hand and standbyoperation (with frost protection).

Adjustable setpoint for roomtemperature during daytimeoperation.

Interface

Simple programmeselectionProgramme selection at theboiler is by use of the centrerotary switch. The use ofclearly defined symbols foreach of the operatingpositions ensures operation isboth simple and error-free.

Commissioning andservicingCommissioning and servicingpersonnel can access theTopTronic controller on aseparate level to the user.This avoids the need to alterprogramme settings made bythe user. Access is gainedvia a password system.

Data interrogationand inputAll operating parameters canbe read and changedmanually at the controller.Alternatively programming viaa PC can be done using theRS485 port.

Perfect communicationThe interface betweenTopTronic controllers androom sensors is via a databusnetwork.

Remote fault findingRemote diagnosis is possiblevia a telephone modem link.

Calendar clockThe current date and time arepre-set during manufacture.

The controller will function forup to five years in the eventof a power interruption.

Summer/winter operation isautomatically changed overby the built-in calendar clock.

Boiler sequencingThe Hoval TopTronic systemis suitable for sequencing twoboilers with either on/off,modulating or pre-mixmodulating burner controls.

Main operating featuresSeveral TopTronic controloptions are available formatching with the Hoval boilerrange.

● Up to two variabletemperature and oneconstant temperaturezone can be linked toeach controller.

● Two individual weathersensors can be added percontroller.

● Each variable temperaturezone can be weathercompensated and linked toa room sensor if required.

● Each controller will alsocontrol a calorifier primarypump for DHWtemperature regulation.

● Can be interfaced with all types of burner controls.

Individual timeprogramme selectionThree individual timeprogrammes can be pre-setto meet the needs of theend-user.

Comprehensive displayAs well as indicating the timeand boiler/DHW temperatures,the display will also showoperating conditions, burnerrun times (and starts) andfault conditions.

Safety functionsThe TopTronic control has in-built safety functions toensure continued safeoperation of the plant at alltimes. These include frostprotection, minimum andmaximum temperature limitsand boiler start protection.Clearly defined operatinglevels ensure system integrityis maintained.

Efficient operationEconomic and environ-mentally friendly performanceare at the heart of the newHoval TopTronic system.

These include:● Reduced burner stop/start

cycling to improve emissions

● Optimised starting facilitywith start stages andselectable heating curves

● Two stage or modulating burner control

These programmes enablethe heating and hot watersystems to best match theuse of a facility, thusmaintaining a comfortableand energy efficientenvironment.

Databus connectionsUp to two TopTronic controllers can be fitted directly intothe boiler control panel on most models (see productbrochures for details), enabling control of up to fourvariable temperature, two constant temperature and acalorifier primary circuit. These are linked together bydatabus connections. On the UltraGas AM and TopGascondens boilers this gives a direct link to the modulatingpre-mix controls.

Separate control panelUse of the databusconnections will also allowup to five controllers to belinked together. With largeinstallations the TopTroniccan be mounted in aseparate control panel ifrequired.

For medium and large oil and gas boilers with pressure jet burners

For small oil and gas boilers with pressure jet or atmospheric burner

For gas boilers with modulating pre mix burner

Optional RS roomstationsThe RS10 room station canbe remotely connected to anyHoval boiler fitted with aTopTronic controller, to provideremote monitoring of boilerstatus and adjustment of pre-programmed settings withinthe TopTronic controller.

These include:● Room temperature.● Heating and hot water

programmes.● Absent, party and holiday

The display normally indicatesdate, time and roomtemperature together withoutdoor/system temperatures,parameter settings and faultconditions. In addition theRS10 provides the facility to‘block programme’ time clocksettings.

The RS30 room station isavailable to link directly to asingle Hoval UltraGas orTopGas boiler only (i.e. withouta TopTronic controller fitted),and provides the samefeatures as the RS10, exceptthat it will only control a single,directly compensated circuit.
