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 turns 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. Refer to Section 17 for more details.
• The Voltage can be linearly interpolated using the above table to determine the desired PWM or unit output.
