The temperature change of TK1
cannot be detected even after
Compressor 1 starts operating.
• Check the TK1 sensor
installation.
• Check the TK1 sensor resistant
characteristics.
• Check the misconnection of TK1,
TK2, TK3, TK4, or TK5.
• Check the SV3E and SV3F valve
error.
• Check the oil circuit capillary
clogging and non-return valve
error.
• Check the hibernating refrigerant
in compressor.
The temperature change of TK2
cannot be detected even after
Compressor 2 starts operating.
• Check the TK2 sensor
installation.
• Check the TK2 sensor resistant
characteristics.
• Check the misconnection of TK1,
TK2, TK3, TK4, or TK5.
• Check the SV3E and SV3F valve
error.
• Check the oil circuit capillary
clogging and non-return valve
error.
• Check the hibernating refrigerant
in compressor.
The temperature change of TK3
cannot be detected even after
Compressor 3 starts operating.
• Check the TK3 sensor
installation.
• Check the TK3 sensor resistant
characteristics.
• Check the misconnection of TK1,
TK2, TK3, TK4, or TK5.
• Check the SV3E and SV3F valve
error.
• Check the oil circuit capillary
clogging and non-return valve
error.
• Check the hibernating refrigerant
in compressor.
The temperature change of TK4
cannot be detected even after
Compressor 4 starts operating.
• Check the TK4 sensor
installation.
• Check the TK4 sensor resistant
characteristics.
• Check the misconnection of TK1,
TK2, TK3, TK4, or TK5.
• Check the SV3E and SV3F valve
error.
• Check the oil circuit capillary
clogging and non-return valve
error.
• Check the hibernating refrigerant
in compressor.
The temperature change of TK5
cannot be detected even after
Compressor 5 starts operating, or
the temperature difference from that
of the other TK sensor changes only
in the specified range for a given
time or longer.
• Check the TK5 sensor
installation.
• Check the TK5 sensor resistant
characteristics.
• Check the misconnection of TK1,
TK2, TK3, TK4, or TK5.
