Penyelesaian
Masalah
Perhatian
Be sure to turn off the power switch before connecting or disconnecting
connectors, or parts may be damaged.
Replace the sensor tekanan rendah.
Replace the unit outdoor PCB
(A1P).
Replace the sensor tekanan rendah.
Replace the unit outdoor PCB
(A1P).
Reset the operation, and then
restart the unit outdoor.
1. Mount the low pressure
gauge.
2. Connect the checker (
3) for
VRV.
Are the characteristics of the low
pressure sensor normal? (Make
a comparison between the
voltage characteristics (
2) and
the gauge pressure.)
NO
YES
If the PCB pressure
detection normal? (Make a
comparison between the
checker (
3) pressure data
and the voltage
characteristics (
2).)
NO
YES
Are the
