the
temperature
of
the
indoor
heat
exchanger
exceeds
the
overheating
prevention
line
during
heating
due
to
the
operating
frequency
or
the
nature
of
the
operation,
the
frequency
is
lowered
by
approximately
5
to
10
Hz.
After
that,
the
frequency
is
lowered
by
approximately
5
to
10
Hz
once
every
60
seconds.
When
the
temperature
of
the
indoor
heat
exchanger
goes
below
the
overheating
prevention
line,
the
frequency
is
raised
by
approximately
5
Hz
once
every
60
seconds,
and
normal
operation
is
restored.
If
the
frequency
is
lowered
to
35
Hz
without
the
temperature
of
the
indoor
heat
exchanger
decreasing
and
this
condition
lasts
for

overheating
if
the
temperature
of
the
outdoor
heat
exchanger
exceeds
approximately
57°C
during
cooling,
the
operating
frequency
is
lowered
by
approximately
5
to
15
Hz.
After
that,
the
frequency
is
lowered
by
approximately
5
to
10
Hz
once
every
60
seconds.
When
the
temperature
of
the
outdoor
heat
exchanger
goes
below
approximately
55°C,
the
frequency
is
raised
by
approximately
5
Hz
once
every
60
seconds,
and
normal
operation
is
restored.
If
the
frequency
is
lowered
to
35
Hz
without
the
temperature
of
the
outdoor
heat
exchanger
decreasing
and
this
condition
lasts
for
1

the
compressor
will
be
stopped.

Control
for
prevention
of
discharge
overheating
If
the
discharge
temperature
exceeds
approximately
105°C
during
compressor
operation,
the
operating
frequency
is
lowered
by
approximately
5
Hz.
After
that,
the
frequency
is
lowered
by
approximately
5
Hz
once
every
60
seconds.
When
the
temperature
of
the
outdoor
heat
exchanger
goes
below
approximately
104°C,
the
frequency
is
raised
by
approximately
5
Hz
once
every
60
seconds,
and
normal
operation
is
restored.
If
the
frequency
is
lowered
to
35
Hz
without
the
discharge
temperature
decreasing
and
this
condition
lasts
for
1
minute,
the compressor will be stopped.
(5)
Control
for
prevention
of
indoor
heat
exchanger
freezing
If
the
temperature
of
the
indoor
heat
exchanger
goes
below
approximately
5°C
during
cooling,
the
operating
frequency
is
lowered
by
approximately
5
Hz.
After
that,
the
frequency
is
lowered
by
approximately
5
Hz
once
every
60
seconds.
When
the
temperature
of
the
indoor
heat
exchanger
rises
above
approximately
5°C,
the
frequency
is
raised
by
approximately
5
Hz
once
every
60
seconds,
and
normal
operation
is
restored.
If
the
temperature
of
the
indoor
heat
exchanger
goes
down
to
approximately
0°C
and
this
condition
continues
for
4
minutes,
the
compressor
is
stopped.
When
the
temperature
rises
above
approximately
2°C,
normal
operation
is
restored.
