(11)  Drain motor (DM) control [Applicable type: FDT, FDTW, FDTS and FDR]

(a)  Drain  motor  (DM)  start  operation  at  the  same  time  when  compressor  ON  at  cooling  and  dehumidifying  mode  and 

keeps operating for 5 minutes after operation stop, the anomalous stop, thermostat OFF and switching from cooling or 
dehumidifying operation to fan or heating operation.

Stop 

(1)

Indoor unit operation mode

Control A

Control B

Compressor ON

Compressor OFF

Cooling

Dehumidifying

Heating

Fan

 (2)

Note (1) Including the stop from cooling, dehumidifying, 
 

 

fan and heating operation and the anomalous stop.

 

(2) Including the “Fan” operation according to the 

 

 

mismatch of operation modes.

(i)  Control A

1)  If the float switch detects any anomalous draining condition, the unit stops with the anomalous stop (displays E9) 

and the drain pump starts.

2)  The drain motor keeps operating while the float switch is detecting the anomalous condition.

(ii)  Control B
 

If the float switch detects any anomalous drain condition, the drain motor is turned ON for 5 minutes, and at 10 seconds 
after the drain motor OFF it checks the float switch. If it is normal, the unit is stopped under the normal condition or, if 
there is any anomalous condition, E9 is displayed and the drain motor is turned ON. (The ON condition is maintained 
during the drain detection.)

(b)  Drain motor (DM) interlock control

(i)  Start conditions
 

Depending on the function setting of the remote controller, the drain motor is turned ON under either one of the 
following conditions.
1)  During heating operation (Both the thermostat ON/OFF)
2)  During heating operation (Both the thermostat ON/OFF) + Fan operation
3)  Fan operation

(ii)  Stop conditions
 

The drain motor is turned OFF 5 minutes after the stop of operations 1) to 3) above.

(12)  Operation check/drain pump test run operation mode

(a)  If the power is turned on when the dip switch (SW7-1) on the indoor PCB is ON state, it enters the mode of operation 

check/drain pump test run. It is ineffective (prohibited) to change the switch after turning power on.

(b)  When the communication with the remote controller has been established within 60 seconds after turning power on by the 

dip switch (SW7-1) ON, it enters the operation check mode. Unless the remote controller communication is established, it 
enters the drain pump test run mode.

Note (1)  To select the drain pump test run mode, disconnect the remote control connector (CNB) on the indoor PCB to shut down the remote controller 

communication.

(c)  Operation check mode
 

There is no communication with the outdoor unit but it allows performing operation in respective modes by operating the 
remote controller.

(d)  Drain pump test run mode 
 

When the drain pump test run is established, only the drain pump operates, and during operation the protective functions 
by the microcomputer of indoor unit become ineffective.

(13)  Indoor heat exchanger anti-frost (anti-frost control)
 

Thermostat OFF control

1)  Thermostat  is  turned  OFF  depending  on  the  temperature  detected  with  the  heat  exchanger  sensor  (Th

I

-R1,  R2) 

during “Cooling” and “Dehumidifying” operations.

1.0

Forced thermostat OFF

Thermostat ON OK

Heat exchanger temperature

5-min timer

Temperature drop

Temperature rising

10°C

2)  For 4 minutes after the thermostat ON, the forced thermostat OFF control for the anti-frost protection is not effective.

a) 

When temperatures detected by the heat exchanger sensors Th

I

-R1 and R2 are higher than the anti-frost protection 

temperature at 4 minutes after the thermostat ON, the detection starts from the state of thermostat ON.

3)  If  the  temperature  detected  with  the  heat  exchanger  sensor  Th

I

-R1  or  R2  has  stayed  below  the  anti-frost  protection 

temperature (-0.5°C) continuously for 5 minutes after 4 minutes of the thermostat ON operation, then the thermostat is 
turned OFF forcibly.

 

The thermostat will be turned ON if temperatures detected by Th

I

-Ra and R2 picked up in the thermostat ON range.

4)  “Anti-frost” signal is sent to the outdoor unit.
