To fix problem #2, I removed the bottom plate of the control unit by
taking out the two small Phillips head screws. I turned an adjusting
screw on the thermostat relay to narrow the gap between the relay arms,
thereby reducing the temperature deviation required to cycle the
thermostat.

You know, I thought there was a thermal-swtich in the blanket, that
controlled the relay in the box, and the control was Yes or No. Not
a thermal rheostat. ???

CAUTION: The adjustment screw will have 120V if the
controller is plugged in. Either use an insulated screwdriver or unplug
the controller before attempting this. You can tell when the gap is
appropriate by turning the adjustment screw and then rotating the
temperature control dial back and forth. You should aim for a position
of the relay arms to cause the relay to open/close with less than a 1
number rotation of the temperature control dial. Before I did this, I
was getting a 2-3 number deviatio
