CA970253/a
When switched on, the controller lights up, goes through a short test routine, and then displays the measured
temperature and starts to control. The output light glows or flashes as heating occurs. The Page key allows
access to parameter lists within the controller; most lists and parameters are hidden and cannot be accessed
by the operator (they contain factory-set parameters which should not be changed). A single press of the page
key displays the temperature units, normally set to °C; further presses reveal the lists indicated in the navigation
diagram, Fig. 4. The Scroll key allows access to the parameters within a list. A single press displays the
temperature units; further presses reveal the parameters in the current list indicated in the Navigation Diagram.
Some parameters are display-only; others may be altered by the operator. To return to the Home list at any
time, press the Page and Scroll keys simultaneously, or wait for 45 seconds. The Up and Down keys are used
to alter the setpoint or other parameter values.
