Outline of specifications
1) The heating operation is performed as follows based
on the detected temperature of Tc sensor or Tcj sensor.
• When [M] zone is detected, the commanded frequency
is decreased from the real operation frequency.
After then the commanded frequency changes every
30 seconds while operation is performed in [M] zone.
• In [N] zone, the commanded frequency is held.
• When [L] zone is detected, the commanded fre-
quency is returned to the original value by approx.
6Hz every 60 seconds.

1) In cooling operation, the drain pump is usually
operated.
2) If the float switch works while drain pump drives, the
compressor stops, the drain pump continues the
operation, and a check code is output.
3) If the float switch works while drain pump stops, the
compressor stops and the drain pump operates. If the
float switch keeps operating for approx. 4 minutes, a
check code is output.
When heating operation stops, in some cases, the indoor
fan operates with [FAN] for approx. 30 seconds.
Remarks
Same status as that
when “thermostat-OFF”
Check code [P10]
NOTE:
When the operation has started or when Tc or Tcj < 30°C
at start of the operation or after operation start,
temperature is controlled between values in parentheses
of A and B.

Use for remote start/stop
When using HA terminal
(CN61), the connecting
connector sold sepa-
rately is necessary.
In a group operation,
connect it to any of
master or follower indoor
unit for use.
HA control
1) ON/OFF is possible by HA signal input from the
remote site when it is connected to the wireless
remote unit or the remote Start/Stop I/F.
2) ON/OFF status is output to HA output terminal.
3) HA I/O specification conforms to JEMA Standard.
