See table 2
• Check connection of thermistor.
• Check resistance value of thermistor.
0 ˚C; 15.0 kΩ
10 ˚C; 9.6 kΩ
20 ˚C; 6.3 kΩ
30 ˚C; 4.3 kΩ
• Check local system if air flow is reduced.
• Check outdoor fan motor.
• Check connection of thermistor.
• Check resistance value of thermistor.
For characteristics, refer to (P2) above.
• Check connection cable for damage or loose connections.
• Check system configuration of remote controller.
• Check that outdoor unit has not been turned off.
• Check connection cable for damage or loose connections.
• Refer to outdoor unit service manual.
• Replace PCB A.
• Check connection of thermistor.
• Check resistance value of thermistor.
For characteristics, refer to (P2) above.
• Use correct remote controller PZ-01RC (Number "BH00J360"
is displayed on the bottom.)
Error
• Check the model selection dip-switches (SW11-9 and
11-10 on PCB B), SW1-7 on PCB A and the actual
model name.
See table 1
• Check the lead wire cable is properly connected
between CN105 on PCB A and CN5 on PCB B.
• Check the PCB A is properly working.
• Check the connection cable (accesory) is properly
connected between CN20 on Lossnay PCB and
CN120 on PCB B.
• Check the power to Lossnay unit is properly supplied.
• Check the SW7-1 of Lossnay unit PCB is ON.
• Check the water level in the unit. If the drain pump is
broken the water level becomes high and then error
code 2600 will be displayed.
• Check the lead wire cable of the water sensor is
properly connected to CN10.
• Check the lead wire cable of the supply air thermistor
is properly connected to CN9.
• Check if SW11-1 on PCB B is OFF.
• Check Lossnay PCB and the service handbook.
• Check the drain pump if it works properly and replace
when necessary.
