8. Fan characteristics
The document includes fan characteristic curves for various models, showing the relationship between airflow (SCFM) and external static pressure (in. W.G.) for both standard and maximum static pressure conditions. These curves are provided for different fan taps (L, M, H).
Note: The factory wiring corresponds to the standard static pressure. To adjust the indoor unit to the maximum static pressure, the motor wiring needs to be changed. Refer to the IOM for specific operations.
9. Sound data
The document provides sound data, including sound pressure levels and Noise Criteria (NC) curves, for various models. The measurements are taken with a microphone placed at a specified distance from the indoor unit, with different fan taps and external static pressures.

The PWM duty cycles are: 0%, 20%, 60%, 80%, 100% 0% Initial operation Up to 2 seconds, until first measurement is ready. 20% Normal operation - monitoring 60% Alarm Concentration of refrigerant above 10'000 ppm. The Alarm signal is on while a concentration above 10'000 ppm is detected and stays on for 30seconds after the concentration has returned below 10'000 ppm. 80% Sensor fault Sensor reading may not be accurate. This can be due to a permanent error, due to a temporary condition (e.g., ambient conditions outside operating range), or due to a temporary internal error. 100% Power supply OFF |
