After sefety
for defrosting
The compressor shall be forced ON regardless of R sensor

12. Handling of the AT sensor
Item Explanation
Outline
AT sensor is on PFB. Therefore, it affected heat from other parts or
neighboring instruments.
To reduce these influence, following value regard as sensor value.
Within 1min
after Power supply ON
AT sensor regards it as 30
o
C.
When 1min passes, store actual AT sensor temperature.
(To stabilize PFB Unit test in LAB any temperature condition.)
After that
Store AT sensor temperature when compressor switched from OFF to
ON.
When sensor is
abnormal
If AT sensor value is abnormal, (Over 107
o
C or Under -38
o
C)
AT sensor regards it as 28
o
C, and continue control other instruments
normally.
