V),
current
error
(over
17
A),
or
temperature
error
(over
90°C)
is

does
not
receive
a
serial
signal,
it
will
stop
approximately
30
seconds
later.
Note
that
this
is
true
only
of
normal
operation;
in
test
mode,
it
does
not
stop
and

on
the
test
mode
commands.
2-8 Four-way rotary valve
The
four-way
rotary
valve
will
not
switch
when
there
is
a
large
difference
in
refrigerant
pressure.
To
make
the
four-way
rotary
valve
switch
normally,
switching
is
delayed
by
approximately
3
minutes
and
the
refrigerant
pressure
difference
is
decreased
first.
Also,
the
temperature
of
the
indoor
heat
exchanger
at
the
time
of
compressor
activation
and
the
temperature
150
minutes
after
activation
are
compared,
and
it
is
determined
whether
or
not
they
are
suitable
for
the
opera
mode
at
that
time.
If
they
are
not
suitable,
a
four-way
rotary
valve
error
results
and
the
compressor
is
stopped.
