Green Controller Light
Indicates when lighted that the temperature of the Resin component in the heater
is within +/- 5° F of dial set point.
Amber Controller Light
Indicates when lighted that the temperature of the Resin component in the heater
is more than +/- 5° F cooler than dial set point.
Red Controller Light
Indicates when lighted that the temperature of the Resin component in the heater
is more than +/- 5°F warmer than dial set point.
10. A-PRIMARY HEATER
CONTROLLER
Controls the temperature of the liquid maintained by the A Primary Heater. Set
Control Selector (dual scale, Fahrenheit or Centigrade) to the desired
temperature. From this point, the temperature control is completely automatic.
