3. Programming the temperature profile.
A total of 6 steps can be programmed for this controller. Each step contains the temperature (C-X)
and time duration (t-X) setting. They are represented by the symbol C-X and t-X, where “X” is the
step number (e.g. temperature value of Step 4 is represented by C-4 and time value of step 4 is
represented by t-4). The character, “t”, is displayed as the symbol, “
T
”. Time is defined as the
duration between the last step and the next step. Please make sure the time is long enough for
the heater to heat up the oven. If the time is set too short, the temperature may not be able to
reach set temperature, before it jumps to the next step. The time unit is in minutes with 1 minute
resolution. If the recipe only needs one step, you can program the time of the rest of the steps to
zero.
To program the temperature profile, press SET key once. The display will show C-1 for one
second and then display the temperature setting for step 1. Use “+” and “-” keys to change the
setting. When finished, press the SET again to confirm the change. The display will show t-1 for a
second and then change to the time setting for step 1. Use “+” and “-” keys to change the setting.
When finished, press the SET again to confirm the change. The display will go to the step 2
setting. The following is the flow chart (Figure 6) for the setting procedure.
The temperature setting will not be changed if SET key is not pressed (confirmed). After
programming the necessary cooking steps, you can finish programming by pressing the SET
repeatedly until the display passes t-6 and displays the current temperature. You can also leave
the controller alone. The display will return to the normal display mode if no key is pressed within
15 seconds.
