No, we can't modify the autotrim to ONLY output 12V, it will still output whatever is put into it. However, the older autotrim is not suitable for sustained 24V input. When a current load is put on it at 24V, it's lifespan is shortened. The new model (which is wired the same way) is able to handle 5A @ 24V. We'll take a look at yours and most likely exchange it for a new version. In the meantime, you'll want to set up a convertor in your aircraft to bring the input voltage down to 12V. RMA to follow soon. Thanks!

So Doug, I would send him the s/n on your unit to see if it is "at risk".   This means it won't address my trim speed issue until I reduce the voltage to 12v or establish a PWM interface (bi-directional dc motor pwm schematic with airspeed switch input, anyone?) but it will prevent some form of failure they must be concerned about.
