Fan speed names don't align

[Sammy1Am]

The capabilities packet for my air handler says it should support 3 fan speeds, but the "Actual Fan Speed" sensor is reporting speeds like "Very Low" and "Quiet".

Setting the climate control to "Low" results in "Quiet", "Medium" is "Low" (IIRC).

Need to make sure these all line up properly.

It gets worse. My air handler supports three fan speeds, but:

It cycles between OFF, Quiet, Very Low, Low, and Powerful. I haven’t explicitly tried forcing fan speeds for mapping purposes yet, but it seems to be a mess.

My mapping however:

• Low maps to Quiet actual speed
• Medium maps to Low actual speed
• High maps to Powerful actual speed

Meanwhile, my 5-speed wall unit:

• Quiet maps to Super Quiet actual speed
• Low maps to Quiet actual speed
• Medium maps to Low actual speed
• High maps to Powerful actual speed
• Very High maps to Super Powerful actual speed

The Very Low mode seems to only be engaged on my air handler after the heating setpoint has been met, and likely is controlled by the Thermal Off Fan setting.

Supported Speeds: 5	Set Speed	"Actual" Speed
Any	0	Unit is in idle
?	1	Haven't confirmed this one yet
1	6	!
2	2
3	3
5	4	(this is fine, there isn't a speed 4 🤷‍♂️ )
6	5

Supported Speeds: 3	Set Speed	"Actual" Speed
Any	0	Unit is in idle
?	1	"Actual" 1 is present during pre-heating
2	2
3	3
5	4	(this is fine, there isn't a speed 4 🤷‍♂️ )

So, weirdness with there being no set-speed 4 aside:

• Low/Medium/High/Very High = Quiet/Low/Powerful/Super Powerful seems to line up numerically.
• Very Low seems to be a special case for preheating and thermal off (haven't confirmed if this actually is a real-life fan-speed difference, or just a difference in reporting)
• The lowest speed on 5-speed units maps to 6, but that makes sense since "1" was already the special Very Low case, and they'd run out of small numbers.

I think it's not unreasonable to maybe change the names of "actual" speeds 2-6 so that they do match up with the set speed names. I'm in favor of renaming them to match something more traditional like "Quiet,Low,Medium,High,Very High" (we can preserve the "powerful" in code comments :P )

"Very Low" would remain a special speed that only shows up in the "Actual Speed" sensor.

Closing as resolved in #42.
