Terminology Constant temperature operation Heating circuit In constant temperature operation, the heating water is constantly heated to the selected boiler water temperature. A heating circuit is a sealed circuit between the boiler and radiators, in which the heating water circulates. Heating program Heating circuit pump The heating program determines whether you heat your rooms and DHW, or only heat DHW, or whether you shut down your heating system with frost protection monitoring.
Terminology (cont.) Summer mode Heating program " ". At warmer times of the year, i.e. when the rooms do not have to be heated, you can stop heating mode. The boiler remains enabled for DHW heating. Cylinder primary pump Circulation pump for heating the DHW in the DHW cylinder. Drinking water filter 5592 669 GB A device that removes solids from the water. The drinking water filter is installed in the cold water pipe upstream of the DHW cylinder or the instantaneous water heater.
