I learned something new, the efficiency rating is really different than what occurs when in use, so 90% efficiency pans out as less than 70%. So the work here is to keep the temperature of the motor down to maintain efficiency.

the difficulty is not all motors are of course able to be programmed so while this fix will help those that are it does point out that there are still big energy savings to be had to replace existing 'dumb' motors. Now I will mention the obvious, none of them should be on the net but I can see a local network that is air gap being useful
