The displayed value depends onthe temperature controller setting. The maximumdisplay value is reached only if the control buttonis set to “Pos. ” at the end of the respective hea-ting cycle.If any other controller setting is chosen, the poin-ter will indicate a lower temperature value.8. Setting range limitation (EWH, EKR, EKA)In order to exclude the risk of accidental scaldingwith hot water, the setting range of the tempera-ture controller can be limited to max. 65°C. Elec-trically disconnect the device from the mains (allpoles must be disconnected). Set control buttonto “Pos. “. Open the connection chamber andpull out the bolt from the bore in the back wall ofthe control panel. Reinsert bolt in the bore, inser-ting the long shaft first.9.

If the water is very hard, either of the following options is recommended: toconnect a commercially available standard descaling device upstream of the tank, to use an anti-scaling tank of Austria Email AG or to observe a maximum operating temperature of approximately65°C (setting “Pos. ”). The bare-tube heat exchanger of the EKR series must be flushed properlybefore the initial installation is performed. If the bare-tube heat exchanger is not used, the outer tubeends must be sealed to prevent back-cooling. The drinking water quality must be appropriate toensure proper operation.It is recommended to fit a water filter upstream of the device to keep the tank free of dirt and otherparticles.Should a device, at the point of delivery, clearly display a malfunction, damage or other defect,this must not be fitted, installed or used in the system.
