Error diagnosis and countermeasure flow chart
Is temperature sensor
connector connections
are normal?
No
• Sub-cool circuit in the
outdoor unit
Check and correct connection
Yes
Is the value of temperature
sensor resistance normal?*
No
Replace sensor
(Plus)
Yes
Replace outdoor unit PCB
* Sensor resistance 100 ༮ over (open) or 100 ȳ below (short) will generate error
(Plus II)
Note: Temperate sensor resistance vary with temperature, So compare temperature sensor resistance value
according to outdoor unit temperature by referring below table (·5% tolerance)
Air temperature sensor: 10୅ = 20.7༮ : 25୅= 10༮ : 50୅= 3.4༮
Pipe temperature sensor: 10୅ = 10༮
: 25୅= 5༮ : 50୅= 1.8༮
