Fan control commands are available for thermostat revisions with an integrated fan system: Fan control commands are available for thermostat revisions with an integrated fan system:
1. `fan` - show fan stats: `fan_pwm`, `abs_max_tec_i`, `auto_mode`, `k_a`, `k_b`, `k_c`. 1. `fan` - show fan stats: `fan_pwm`, `max_abs_i_meas`, `auto_mode`, `k_a`, `k_b`, `k_c`.
2. `fan auto` - enable auto speed controller mode, where fan speed is controlled by the fan curve `fcurve`. 2. `fan auto` - enable auto speed controller mode, where fan speed is controlled by the fan curve `fcurve`.
3. `fan <value>` - set the fan power with the value from `1` to `100` and disable auto mode. There is no way to completely disable the fan. 3. `fan <value>` - set the fan power with the value from `1` to `100` and disable auto mode. There is no way to completely disable the fan.
Please note that power doesn't correlate with the actual speed linearly. Please note that power doesn't correlate with the actual speed linearly.
4. `fcurve <a> <b> <c>` - set coefficients of the controlling curve `a*x^2 + b*x + c`, where `x` is `abs_max_tec_i/MAX_TEC_I`, a normalized value in range [0,1], 4. `fcurve <a> <b> <c>` - set coefficients of the controlling curve `a*x^2 + b*x + c`, where `x` is `max_abs_i_meas/MAX_TEC_I`, a normalized value in range [0,1],
i.e. the (linear) proportion of current output capacity used, on the channel with the largest current flow. The controlling curve is also clamped to [0,1]. i.e. the (linear) proportion of current output capacity used, on the channel with the largest current flow. The controlling curve is also clamped to [0,1].
5. `fcurve default` - restore fan curve coefficients to defaults: `a = 1.0, b = 0.0, c = 0.0`. 5. `fcurve default` - restore fan curve coefficients to defaults: `a = 1.0, b = 0.0, c = 0.0`.
