I've recovered an indoor part of an air conditioner with the wish to
turn it into a fan coil unit to heat a workshop. I have about 2 tonne
of 80C water to dissipate from a wood burner.

Manual at

http://nagyker.columbus-klima.hu/wri...BAB_24LUAR.pdf
and specifically page 12.

As this is an inverter model I was half expecting the motor to be
three phase but it now looks like it is a single phase ( 50Hz 42W 220V
on motor) with a remote start capacitor, and 3 sets of windings.

The three speeds look strange 540, 480 & 390 rpm.



Also apart from blue, purple, red, white and black wires to the motor
there are a second set of thinner black red and white wires pass to
the back of the motor.

I'm looking for insights as to whether I can run the fan without the
control board, on any one of the speeds, any ideas?
