independent of the defrosting signal.
• When the power relay becomes ON after expiration of the time TE,
defrosting will be started immediately with input of the defrosting signal.
• Once defrosting has been completed, the defrosting signal is not
accepted for the time TE.
• When a defrosting signal has been given as input at the time of stop
by means of the start/stop switch or at the time of OFF timer count-up,
defrosting is executed before operation stop.
• The defrosting signal is not accepted at the time of overload input.

The 50 minutes of defrosting
prohibition are counted from
Thermostat ON after start/stop
switch ON. When the thermostat
is OFF at the time of start/stop
switch ON, the 60 minutes will be
counted from the time of thermostat
ON. The initial OFF time is not
counted. Counting starts when the
thermostat becomes ON, and the
count then continues even if the
"Automatic"
heating
thermostat becomes OFF.

In case of switching from "Heating"
the reversing valve is held for 3
minutes.

The defrosting signal is not
accepted with overload input, and
the operation becomes as shown
below when the overload input
disappears.

When
previously
the
defrosting signal existed

defrosting
will
start
immediately.
(2)
In cases other than the
above, defrosting will be
executed with a defrosting
signal in the condition
without overload input.
