7. Single-step mode
In this mode, the controller will hold temperature at one set value (C-1) continuously as long as
the controller is powered on. Even if the controller is powered off and turned on again, it will
resume working in this mode. You do not need to enter any other program steps in this mode.
To enter the single-step mode, the user need to set the parameter “PrG” to “off”. Under the
normal operating mode, to recall a recipe, press and hold SET key for 3 seconds until the
Parameter Window displays “LOCK”. Release the SET. The display will show “0”. Use “+” and “-”
keys to adjust the display to 3 and press SET. The display will show “PrG” for a second and then
the value “on”. Use “+” or “-” key to toggle between “on” to “off”. Select “off” and press SET key if
you want to enter the single-step mode. Otherwise, select “on” and press SET key to enter the
program mode. The controller will go back to the normal operating mode. To set the temperature,
press SET key once, and the left window will show “C-1”. Use “+” or “-” key to adjust the
temperature in the right window, then press SET to save and exit. Figure 13 shows the flow chart
of how to switch to the single-step mode.
