OperatinginstructionsATAGQ-Series

TheATAGQboilerisaroomsealed,condensing

andmodulatingcentralheatingboiler,withorwit-

houtanintegratedhotwaterfacility.

The boiler is provided with a compact stainless

effectontheheatexchangerandthefunctionof

theboiler,isdrainedthroughaninternalsiphon.

Theboiler is provided with anintelligentcontrol

system(CMSControlManagementSystem).The

boileranticipatestheheatdemandofthecentral

heatingsystemorthehotwaterfacility.

Whenanoutsidesensorisconnectedtotheboiler,

theboilerworksweatherdependantly.Thismeans

thattheboilercontrolmeasurestheoutsidetem-

peratureandowtemperature.Withthisdatathe

boilercalculatestheoptimalowtemperaturefor

theinstallation.

Description of the boiler

Room sealed boiler

The boiler retreives its com-

bustion air from outside

then discharges the ue

gasses to the outside.

Condensing

Retrieves heat from

the ue gasses. Water

condensates on the heat

exchanger.

Modulating

Higher or lower burning

according to the heat

demand.

Stainless steel

Super solid kind of steel

which keeps its quality for

life. It will not rust or erode

in contrast to composition

materials, like aluminium.
