Notes
Mounting
Flow measuring section
The mounting orientation is optional, the mounting location (heat or cold side) must
correspond to the meter type.
On heat energy meters or combined heat/cooling energy meters, the mounting location of
the cooling side corresponds to the return
and the mounting location of the heating side
to the flow
.
On cooling energy meters, the mounting location of the heating side corresponds to the
return
and the mounting location of the cooling side to the flow .
On meters with adjustable mounting location 'P', the mounting location, heat side, is
displayed as 'hot'. The mounting location, cooling side is displayed as 'cold'.
NOTICE
The mounting location is locked and can no longer be changed once the meter recognizes
a volume of 10 liters. After that, 'P' is no longer displayed: 'hot' or 'cold'.
Settling paths are not required, neither upstream of nor downstream from the meter. If the
meter is installed in the common return of 2 heating circuits, e.g. space heating and DHW,
the mounting location must be at an adequate distance from the T-piece (min. 10 x DN) to
allow the different water temperatures to properly mix.
Thoroughly flush the plant prior to installing the meter.
