5.8 Setting Soak Time
1) Continuing from section 5.7, while the green display is alternating between
“SL1” and the soak temperature, continue pressing the Mode button until
the green display flashes “St1” (Figure 17). The display will alternate
between “St1” and the soak time (in minutes). As in the case of the ramp
time, this is the first of 8 soak times available. Soak time 1 is preset to 0 so
that as soon as the temperature reaches the set point, the controller
switches to the next ramp to reach the next temperature set point.
2) To change the soak time, press the up or down arrow button until the
desired time is achieved.
Note: It is necessary to set ramp time 1, soak level 1, and soak time 1 before
setting ramp 2 and soak 2. Simply continue pressing the Mode button until
rt2, SL2, and St2 appear in the green display. If no more temperature levels
are required in the cycle, return to the main operating mode by pressing
and holding down the Menu button until the red display reads the current
temperature. Ramp time 2 is preset to 5 minutes. Soak level 2 is preset to 40°F.
Soak time 2 is preset to 0. The remaining 6 ramp times are preset to 0. If the
ramp time is set to 0, the ramp will be skipped.
