Notes:
1. The fan speed index is related to the fan speed in rpm and can take any integer value in the range 1 (slowest) to 30 (fastest).
2. Silent mode:
0: night silent time 6h/10h; 1: night silent time 6h/12h; 2: night silent time 8h/10h; 3: night silent time 8h/12h; 4: no silent mode; 5: silent mode;
6: super silent mode.
3.
Te: Low pressure equivalent saturation temperature (°C) Tes: Target Te value. Tc: High pressure equivalent saturation temperature (°C) Tcs: Target Tc value
.
