1231C controller.
Be sure to mount the 1209B/1221B/1221C controller so as to allow access
to the adjustment screws. Although not usually necessary, a thermal joint
compound can be used to improve heat conduction from the case to the
mounting surface.
1231C
The controller should be fastened to a clean, flat metal surface that provides an
adequate heat sink. The mounting surface is an integral part of the overall
heatsinking of the controller, and affects its ability to dissipate heat.
