Any other use of this appliance will beconsidered improper.UNICAL declines any responsibility for any damages or injuries caused by an improperuse; in this case the risk is completely at the user’s responsibility.In order to use the appliance accordingto the scopes it was designed for it is essential to carefully follow the instructions indicated in this guide.3 - WATER TREATMENT• The hardness of the mains water supply conditions the frequency with which the heat exchanger is cleaned.• In hard water areas where the main water can exceed 15°f total hardness, a scale reducing device isrecommended. The choice of this device has to be made taking into consideration the characteristics ofthe water.• In order to improve the resistance to lime scale it is recommended to adjust the domestic hot water temperatureas near as possible to the one you really require.• The use of a modulating room thermostat reduces the dangers of lime scale formation.• We recommend you to check the state of cleanliness of the domestic hot water heat exchanger at the end ofthe first year and subsequently, on the basis of the lime scale found, this period can be extended to two years.2

Operating instructionsReset key/error code display”Chimneysweeper” function indicator ledThis key has a dual function:- it will reset correct boiler operation after the cut-off devicehas shutdown the boiler (red “G” led indicator illuminated)MODEWARNING!This operation can be carried outexclusively by personnel from authorizedAfter Sales Service centres. The person incharge of the appliance is NOT authorized to activate thefollowing described function.This “N” indicator led will illuminate, when the“Chimneysweeper” function is activated by a qualifiedprofessional service engineer. This means that the boiler willoperate forcefully at the maximum (or minimum) output so asto permit the adjustment operations and the combustionanalysis.- it will display the boiler’s error code, instead of thetemperature “U”, after the fault indicating led “R” hasilluminated.Central heating mode indicator ledMODEThe led indicator “P” will illuminate when there is a requestfor central heating.Temperature control /error code displayThis displays:- The CH circuit temperature (during central heatingoperation)- The CH return temperature (by pressing simultaneouslythe LIGHT BLUE “I” and BLUE “L” keys)- The set temperature of the CH circuit (by pressing theYELLOW “B” key).Power On indicator ledThe led indicator “Q” will illuminate when the boiler isconnected to the electricity supply6

Operating instructionsFault indicator ledWhen this led is illuminated on the display it indicates thatthe boiler has detected a failure in normal boiler operation oris in lock-out due to a permanent failure.The code which identifies the cause can be viewed in placeof the centigrade temperature scale by pressing the LIGHTBLUE “I” reset key (for the list of error codes refer to paragraph5 – “error codes” in the servicing and installation instructionsmanual).6.2 - CONTROL OF THE OPERATINGPARAMETERSCentral Heating circuit temperatureBy pressing the YELLOW key on the control panel it is possibleto control the set value of the CH circuit temperature (valuebetween 30° and 80°).SETSETBurner On indicator ledWhen the “S” led is illuminated it indicates that the burner isfunctioning correctly, both in central heating request modeand in domestic hot water production modeError codeWhen the fault indicator led “R” is illuminated on the display,by pressing the LIGHT BLUE key on the control panel, it ispossible to control the Error codes (for the list of error codesrefer to paragraph 5 – “error codes” in the servicing andinstallation instructions manual).MODELock-out indicator ledWhen this led (G) is illuminated it indicates that the burner’ssafety cut-off device has shut-down the boiler, due to thefollowing causes:- presence of air in the piping (if it is a new system or aftera long inactivity of the boiler).- no gas supplyIf this is the case, and the burner fails to light, it will benecessary to check that the gas supply cock is in the Onposition.MODEIf the cut-off device operates more than 3times, causing boiler shutdown, do not try toreset the boiler yourself. Contact yournearest After Sales Service Centre.6.3 - CHECK LIST BEFORECOMMISSIONINGBefore commissioning the appliance it is recommended tocheck the following points:- Check that the On-Off gas valve, positioned upstream ofthe boiler, is in the On position.- Check that any On-Off valves fitted on the flow and returnpipes for servicing purposes are in the On position.- Check that any On-Off valves fitted on the cold water inletfor servicing purposes are in the On position.- Check that the boiler is connected to the electrical supply;the indicator led “P” on the control panel must beilluminated.- Check the heating system pressure, indicated by thepressure gauge. For correct operation the pressure shouldbe between 0,8 and 1 bar (with the pump not running).- If the pressure falls below 0,7 bar when the system iscold and the boiler not operating, than restore the correctpressure by operating the filling valve foreseen on thesystem.7

Operating instructions6.4 - BOILER OPERATIONCentral Heating modePress the BLUE “L” key and select the mode: Central Heating(the green indicator led “M” will illuminate).SETSETMODEYou can adjust the central heating temperature by keepingthe YELLOW “B” key pressed down, and simultaneouslypressing the keys “+” to increase the temperature or “-” toreduce it.SET6.6 - ELIMINATING THE FAULTSWhen the “Q” led is illuminated on the control panel displayit indicates that the boiler has detected a failure in normalboiler operation or is in lock-out due to a permanent failure.The code which identifies the cause can be viewed in placeof the centigrade temperature scale by pressing the LIGHTBLUE “H” reset key (for the list of error codes refer toparagraph 5 – “error codes” in the servicing and installationinstructions manual).The person in charge of the appliance can try to reset normalboiler operation only in the following cases:- Burner Off indicator led illuminatedFor all the other error codes, the person incharge of the appliance is NOT authorized toreset the boiler. Your nearest Unical authorizedAfters Sales Service Centre should becontacted as soon as possible.SETIf a room thermostat has been installed, checkthat the desired temperature has been set..6.5 - SHUTTING DOWN THE BOILERFor switching the boiler completely Off, switchthe “A” switch in 0 position: the display will be Off.To completely shut down the boiler switch off the mainselectricity supply.Lock-out indicatorled illuminatedDescription:The burner’s lock-out device has intervened due to:- no gas supply- presence of air in the piping (if it is a new system or aftera long inactivity of the boiler).Eliminating the fault:Check that the gas supply cock is in theOn position and press the reset key to restore correctboiler operation.If the cut-off device operates repeatedly (a maximum of 3times), causing boiler shutdown, do not try to relight theboiler yourself. Contact your nearest Unical authorizedAfter Sales Service Centre.- no gas supplyIf the boiler will remain shut down for a longer period, turn theOn/Off gas cock into the Off position and, if fitted, turn off thecold water supply valve.WARNING!If the boiler will remain shut downfor a prolonged period, and frost is likely, theentire system should be drained.However, it is possible to avoid this operationby using specific frost protection productssuitable for multi-metal systems.8
