THE TEMPERATURE CONTROLLER

ABOUT THE ATC™
The Automatic Temperature Controller (ATC) can be
manually programmed to reach a desired temperature or
computer controlled for sophisticated temperature
profiling. The controller automatically determines the best
settings for optimal heating based on the thermal
response of a particular system. It features two
thermocouple inputs and one 24V heater output, allowing
regular or cascade operation. Regular or single loop
control is used for accessories with only a sample
thermocouple. Accessories equipped with a sample and
heater thermocouple use cascade or double loop control.
Cascade control minimizes damage to system
components, allows for over sizing heaters for optimal
heat-up rates and extends heater life by reducing thermal
cycling of the heater.
This manual contains only “quick start” instructions. For
detailed instructions see the included Watlow manuals.
ENVIRONMENTAL
CONDITIONS
The Automatic Temperature Controller (ATC) is intended
for use in light industrial and laboratory environments.
