1. Error
Code
Transmission processor hardware error
2. Error definition and error detection method
Although "0" was surely transmitted by the transmission processor, "1" is displayed on the transmission line.
The address/attribute appeared on the display on the remote controller indicates the controller where an error oc-
curred.
3. Cause
1) When the wiring work of or the polarity of either the indoor or outdoor transmission line is performed or is changed while the
power is on, the transmitted data will collide, the wave shape will be changed, and an error will be detected.
2) Grounding fault of the transmission line
3) When grouping the indoor units that are connected to different outdoor units, the male power supply connectors on the multiple
outdoor units are connected to the female power supply switch connector (CN40).
4) When the power supply unit for transmission lines is used in the system connected with MELANS, the male power supply
connector is connected to the female power supply switch connector (CN40) on the outdoor unit.
5) Controller failure of the source of the error
6) When the transmission data is changed due to the noise on the transmission line
7) Voltage is not applied on the transmission line for centralized control (in case of grouped indoor units connected to different
outdoor units or in case of the system connected with MELANS)
4. Check method and remedy
