A lower limit for the flow velocity can be entered.
• Select
sign
to define a cut-off flow depending on the flow direction. One limit is set for
the positive and negative flow velocity.
• Select
absolut
to define a cut-off flow independent of the flow direction. A limit is set
for the absolute value of the flow velocity.
• Press ENTER.
• Select
factory
to use the default limit of 2.5 cm/s (0.025 m/s) for the cut-off flow.
• Select
user
to enter the cut-off flow.
• Press ENTER.
If
Cut-off Flow
\
sign
and
user
are selected, 2 values have to be entered:
• Enter the cut-off flow.
• Press ENTER.
All positive values of the flow velocity smaller than this limit are set to zero.
• Enter the cut-off flow.
• Press ENTER.
All negative values of the flow velocity greater than this limit will be set to zero.
If
Cut-off Flow\absolut
and
user
are selected, only one value have to be entered:
• Enter the cut-off flow.
• Press ENTER.
The absolute value of all flow velocity values lower than this limit will be set to zero.
The heat quantity is the totalizer of the heat flow.
• Select the unit of measurement for the heat flow (
