I have added 24v water pump and need some help to fix configuration it is fan2
M106 P2 L20 X200 B0.1 H1 T55 S1 C"Water"
when temp reaches 55 degrees, in the console i ask M106 P2
output " M106 P2
Fan 2 (Water), speed: 100%, min: 7%, max: 78%, blip: 0.10, temperature: 55.0:55.0C, sensors: 1, current speed: 7%:"
Question: why it is only 7% ???
if i do M106 P2 H-1 S1 pump works at 100%.

For some reason you cannot use the L or X parameters in M106 for a thermostatic fan.
If you have L and X the fan speed is either 0 or L.
If you have only L the fan speed is either 0 or S.
if you have only X the fan speed is either 0 or default L which is 0.1.
I tested M106 with/without the L and X parameters and that is what I discovered - at least with firmware 3.2.2.
