Using Preset Programs

The SUPER-NUOVA plate features the option of presetting
4 setpoints into its memory. To program a preset, adjust the
heat and/or stir features to your desired setpoints. Press
and hold one of the presets and the unit will beep indicating
those setpoints have been stored in memory. The presets
will be held in memory, even if the unit is unplugged, until
you choose to override it with another preset.
To activate one of the presets, quickly press the correspon-
ding number and the stir and heat features will automatical-
ly adjust themselves.
It may be helpful to set one of the presets at "OFF" "OFF."
This way, the heating and stirring can be shut off quickly.
No. 2 pencil may be used to gently mark up writable preset
surface.
Heating Metal Vessels and
Sand Baths
Metal vessels and sand baths cannot be heated on most
solid aluminum tops because of the tendency for the metal
and the sand to reflect heat back into the top, eventually
exceeding the maximum temperature rating for an alu-
minum top. Because of its advanced electronic control, the
SUPER-NUOVA is capable of precisely regulating the top
plate temperature. Metal vessels and sand baths may be
heated safely without danger to the aluminum top.
Setting the Timer
The timer function on the SUPER-NUOVA can be set to
shut off stirring, heating or both. The timer can be set for a
desired number of hours (1, 2, 4, 8 or 12) or for a non-spe-
cific period of time (Infinity symbol). To set the timer, use
the right and left arrows until the light above the number
corresponds to the desired time. The default setting is turn-
ing off heating only. To change this setting, see "Service
and Calibration/Timer Shutdown."
