Control unit IFunction IOperation

The heating program selector enables you to choose four operating modes:

Summer mode(central heating off)onlyDHWheating;frost protectionfor

the centralheatingsystemisensured.Integralanti-seizingpumpprotection.

Winter mode;inwintermode,the boilerheatsthe heatingwater temperature

to the value set at the heating water thermostat. Accordingto the pump

operatingmode,the circulationpumpoperatesconstantly(factorysetti1'19)

or only parallelto the burner control with/without run-on period.

Select this setting .!!iTwhen connecting control accessories.

Emissionstest mode:

Theemissionstest modeisactivated byrotating theprogramselectorinto

position i. A dot illuminates between the heating water temperature

indicationonthe LCDdisplay,whilstthe system isin emissionstest mode.

The program selector returns automatically to winter mode when it is

released.Afteremissionstest modehas been activated,the boilerheats to

the temperature set at the heatingwater thermostat without modulation

orto the maximumheating water temperature adjustedvia parameterno.

8. Any previouscycle blockwill be cancelled.The red dot between the

heating water temperature indication extinguishes when emissionstest

modeends.Inconjunctionwith DRT/ DWT/ DWTM/ DWTK,the emissions

test symbolwillbe transferred to the function display.Activationonlyon

the boiler.

°, DHWtemperature selection

When gas-fired condensing boilers are combinedwith a DHWcylinder,

setting1-9 correspondstoa cylindertemperatureof15-70°c.

°,

Heating water temperature selection

Thesetting range 1-9 correspondsto a heating water temperature of

20-75 (85)°C.Thesetting on the heating water thermostat willbecome

ineffectivewhen the system is used in conjunction with a digital room

thermostat or a weather-compensated controller.

Pressure di~play

Thisindicatesthe water pressurein the heating system.Innormal

operation,the water pressureshould be between 1.5-2.5bar.

Insummer mode, the circulator pump operates for approx. 30 seconds after

a maximum idle period of 24 hours.

Aburnerstart-up delayisintegrated to avoidfrequent burnerstarts during

the heating mode.Thecycleblockcan be adjusted from0-30 minutes.

Initial start-up

~ Onlyqualified personnel may carry out

ili the commissioningand initial operation

of the boiler and instruct the user.

.Checktheboilerfor leaks.Preventwaterleaks-

.Checkthat allfluegasaccessorieshavebeen

properlyinstalled.

.Openthe shut-off valvesonflow and return.

.An error codeflasheson the displayif the

boiler hasnot beenproperly commissioned.

Fordetails about error codes,seethe abridged

operating instructions.

.Position the operating instructions where they

areclearlyvisible.

.Instructthe userintheoperationofthe boilerand

handoverthe operating instructions.

Saving energy

.histruct the customer about energy-saving

options.

.Usethis opportunity for reducing the heating

temperatureduringnight operationusingcontrol

accessories.

.Adjust the temperaturesoyou are comfortable;

everydegreeof roomtemperature reductionwill

achieveenergysavingsof upto 5 0/0.

.Reduce the room temperature in unoccupied

rooms as far as possible; please observefrost

protection.

.Ensurethat all thermostatic radiator valvesare

fully opened in roomswhere room thermostats

areinstalled.Theymustnotbeblockedbyfurniture

or curtains.

.Positionthe operating instructions where they

are clearlyvisible.

To ensure the reliable and economic

function of a heating system and to

avoiddangers to individualsand prevent

material losses, the system user should

be advised that an approved specialist

should clean and check the heating

system annually.

~Modifications must onlythe carried out

Wolf service engineers.

~Incorrect operation can lead to the

system developing faults.

Please note when using parameter 5

(frost protection/outside temperature),

that frost protection isnot safeguarded

ifyou set temperatures lowerthan 0 °c.

To'preventdamageto the heating system,

cancel night setback when outside

temperatures fall below -12°C. If this

rule isnot observed,icemayaccumulate
