❏ Heater: Auto or Off
The heater setting should be set to “Automatic” when temperatures
are at or below freezing and the display begins to get sluggish. When
the heater setting is “Auto,” the Allegro monitors the display
temperature every five minutes. If the temperature is less than -3° C
then the heater is turned on. When the temperature is above -3° C, the
heater is turned off. The Allegro does this automatically. When the
heater is on it uses 250 mA of current. When the heater setting is
“Off,” the heater is always off.
