NOTES
• As the compressor turns ON and the Indoor fan signal is not available then indoor fan will start to run on medium
PWM speed.
• If the compressor turn ON, during reduced fan operation, the controller will increase the fan speed to the "low
PWM fan limit" if it is running less than the low PWM Limits.
• Indoor fan low and high PWM limits depends upon the model.
• The Voltage can be linearly interpolated using the above table to determine the desired PWM or unit output.
• Compressor turns on with 100% speed request.
Run and Fault Indication Output (Outdoor Board)
To activate, the unit must be wired as illustrated below. If required, a fault output connection terminal is also available to
show any error/fault with the a/c system. RUN/FAULT relay outputs (230VAC/5A MAX) connection.
