Example C
Initial Bath Temperature = 25°C
Program Priority = Temperature
Desired Profile: Cool bath temperature to 20°C as fast as possible.
Increase bath temperature to 55°C as fast as possible.
Repeat 7 times.
This example requires a 2-step program with the number of loops set to 8:

Duration Controller Operation
1 20°C 1 second
Controller cools fluid to 20°C as fast as possible. Until
20°C temperature set point is achieved, “Starting”
appears on the display.
When fluid temperature reaches 20°C, “Running” appears
on the display.
Controller applies heat until 55°C set point for Step 2 is
reached.
2 55°C 1 second
Controller loops back to Step 1, applying cooling until
20°C set point is reached.
Steps 1 and 2 repeat seven more times. When the last
loop has been completed, “Complete” appears on the
display. Fluid temperature is maintained at 55°C until the
set point is changed.
