4.4 Mode 1 Operation
Mode 1 is used for set temperature and mixing control for a set/unlimited period of time and
can be programmed for up to 10 programmable user functions.
The mode display will show the Mode and the program setting. For example, the display
above shows 1-0 for the mode setting, indicating Mode 1 program 0. For this mode
operation, use the Temperature adjustment buttons, RPM adjustment buttons and Time
adjustment buttons to set the Temperature, RPM, and Mix Time.
The temperature can be set from 2°C to 99°C or the Temperature control function can be
turned off by holding down the Temperature adjustment arrow until the Temperature display
reads “off” and audible beep is heard.
Note: During cooling operation, increased fan velocity may be observed.
The timer can also be set to count up by holding down the Time adjustment arrow until the
time display reads “off” and audible beep is heard.
To save the set parameters to the Mode, press and hold the Save button until an Audible
beep is heard.
Press the Start/Stop button to start the operation. As in the figure above, “RUN” will appear
in the function indicator area showing that an operation is in process.
Pressing the Start/Stop button once will “PAUSE” the operation. Pressing the Start/Stop
button again will resume the operation. Upon completion of the operation an audible beep will
sound and the Function indicator will read “END”.
Note: Upon the completion of an operation, the unit will stop mixing. The heat/cool
function will continue to operate at the last set temperature.
To reset a program to the starting point or change function parameters during the operation
of a program, first pause the cycle by pressing the Start/Stop button. Once paused, the
mode cycle will need to be reset by pressing and holding the Start/Stop button for
approximately 3 seconds until an audible beep is heard and the function indicator reads
“STOP”. At this point you can change function parameters or start a new program cycle.
