ASTM C 666. The controller allows for up to 100 cycles in this mode. The
controller is set up to cycle down to 0°F and then up to 40°F for a total of 36
cycles. When the last cycle has been completed, the controller will automatically
go to standby mode.
5.0 Changing Ramp/Soak Cycle Settings
The settings in the cycle recipe can be changed to the user’s needs. The
temperature set points, ramp times, soak times, and number of cycles can be
changed by going into the recipe menu. One cycle can have up to eight
temperature set points. Each temperature set point has an associated ramp time to
reach that temperature set point and a soak time at that temperature. This
controller is preset to have two temperature set points in a cycle.
5.1 Setting Recipe Options
1. Press the Menu button on the front of the controller and hold it down for at
least three seconds until the display changes.
2. Press the Menu button again quickly to change the red display. It may be
necessary to press the Menu button several times until the red display reads “r-S”
