Program Ramp Rate
If you desire to ramp to the set temperature at a specified
rate, depress scroll button until "PR" appears. ("PR" =
program ramp rate, which is the rate of heat increase or
decrease in °C/minutes). Depress up or down button to
give current setting of ramp rate. Depress up or down
button again until you achieve desired setting.
To start the temperature ramp, push the run button. With
the run initiated, the program will commence and the
legend on the display will indicate "RAMP". While a
program is running, the short scroll will contain three
parameters. SP = set point. OP = output power. Time =
time remaining in program ramp to reach set point
temperature. Single depression of the scroll button will
allow you to view each of these parameters.
When the program ramp has ended, an "E" will appear
on the display.
Program Ramp Reset
A running or finished program can be reset by depress-
ing the run/hold button.
After depressing the run/hold button, the parts of the
display associated with programming will be extinguished
and the controller will operate as a single set point
control as described before.
