CONTROL LOGIC DESCRIPTION. 

 

SOFTWARE AND HARDWARE OPERATION POINTS. 

 

1).  CLK Remote clock terminals

.  There are no ”CLK” terminals for remote start/stop in this range of 

     

 units. 

2).  Ioniser & Power electrostatic filter.

  New clean air features provided by the IONISER and the 

4800 Volt powered electrostatic filter. 

3).  Outdoor fan operation.  

Outdoor fan runs on for 15 secs after compressor has stopped. 

4).  Strong function.

  The strong function on the remote will run the indoor fan at super high speed for 

15 mins and then will revert to its previous setting. 

5).  Power LED. 

 Power/Operation indicator lights up red when connected to power and standing by 

waiting for a command from the remote control, (OFF mode).  Changes to green during operation. 

6).  I Feel mode.  

In “I Feel” mode if the control PCB has not received an I Feel signal from the remote 

control within 4 mins the unit will revert to units return air sensor control.  If the I Feel data is then 
received the unit will resume the I feel operation.  The remote control must be in line of sight of the 
unit and measuring the room temperature without any “other” temperature influences. 

7).  TEST Operation.  

For “test operation”,  with unit in standby, press the “sleep” button for 3 secs, 5 

beeps will sound and the unit will run in cooling with high speed indoor fan for 30 minutes. 

8).  AUTO Mode.

  The Auto mode on these units selects either heating or cooling mode according to 

     

 requirements and then runs in that mode until turned OFF.  It does not swap from heating to cooling 

      mode. 

9).  Filter Clean LED.

  The filter clean LED is illuminated when the indoor fan has run for 512 hours. 

    

  Press the reset button on the indoor unit to clear the filter LED after cleaning the filters. 

 

MICROPROCESSOR PCB JUMPERS PLUGS. 

 

There are several 

“Jumpers” 

on the PCB which select the unit model and mode. The PCB’s come 

configured for the model designated by the control box assembly and for this reason the assemblies or 
boards should not be interchanged without first checking the jumpers. 

 
JUMPER DESCRIPTION.  Refer PCB Layout page 18. 
1).  J1, J2 & J3

 on PCB are to choose unit mode.

2).  J4 

is unused.

 

3).  J5

 is for self test mode, when power is switched off short 

J5 

so unit will go into self test mode when 

powered on. Refer page 18. 

4).  J6 

is for cooling only/reverse cycle mode, if 

J6 

is shorted the unit is a cooling only model. 

5).  J7, J8 & J9 

 are model selection jumpers.
