FYI folks found this which shows full list of secret codes on air con unit
Hold down "econ" button, and press the up vent (next to recirculate). Both temp displays will read 00 or 00 0, and you can release the buttons once they do.
Twist the LEFT temp knob clockwise until it reads 19 0.
Twist the FAN knob unti the left temp reads 19 1 (like 19.1).
The right temp display is now a digital speedometer!
For Tachometer turn FAN clockwise untill it reads 19 3.
to cancel just hit the "econ" button again.
