electromechanical T/A ???

[Tim_Lentz@cargill.com]

     A friend and I were talking about the Thermostatic Actuators on SPICA 
     equipped cars. We both thought that having an electromechanical device 
     seemed like a much better way to go. This friend thought he had once 
     saw a digest post about just such a device. Anyone know if this 
     "animal" exists?
     
     Also, isn't there an adjustable screw on the pump, under the T/A, and 
     wouldn't this compensate for a T/A that reads either low or high 
     (throughout it's entire movement) ?
     
     How does one go about getting the cap on the adjusting screw off ?
