Controller Operation
1 20°C 5 minutes
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.
Fluid temperature maintained at 20°C for 25 minutes.
2 20°C 1 second
Controller heats fluid as fast as possible until the 30°C set
point programmed for Step 3 is reached.
3 30°C 15 minutes Fluid temperature is maintained at 30°C for 15 minutes.
4 30°C 45 minutes
Controller slowly heats fluid until 50°C set point
programmed for Step 5 is reached. Ramp rate is based
on the 45 minute step duration.
5 50°C 1 second
Controller then cools fluid as fast as possible until 5°C set
point programmed for Step 6 is reached.
