Outlet
energy
registers
A1
and
A2
The
function
behind
the
“Outlet
energy
registers”
is
that
A1
accumulates
heat
energy
consumed
with
low
outlet
temperature
for
which
the
customer
receives
a
discount,
and
A2
accumulates
heat
energy
consumed
with
high
outlet
temperature
for
which
the
consumer
receives
a
surcharge.
The
energy
calculations
of
a
heat
meter
with
flow
sensor
in
outlet
are
shown
below:
A1

t2

A2

The
outlet
temperature
reference
t5
can
be
factory
‐
configured
as
required,
or
can
be
changed
via
METERTOOL
HCW
after
delivery.
Typical
configuration
is
t5
=
50
°C.

As
the

has
direct

on
the
accuracy
of
outlet

registers
A1
and

the

of

the

from

to
