COOLING
A
heat
pump
can
both
emit
and
absorb
heat.
It
is
therefore
possible
to
cool
the
water
in
the
heating
system.
If
the
room
temperature
rises
above
a
certain
value.
it
is
maintained
at
the
set
value
in
cooling
mode.
Idle
When
the
system
is
idle
.
neither
heating
nor
cooling
takes
place
.
This
status
can
occur
between
the
heating
and
cooling
modes.
