How to change track color by temperature variation
This setting paints the track in up to five colors according to temperature variation se-
lected. The setting [EV. 0.2], for example, paints the track red when the water tem-
perature is between 65.0°F and 65.1°F; yellow when the water temperature is
between 65.2°F and 65.3°F. Thus, the track color changes green, light-blue and pur-
ple in 0.2 degree steps. When the water temperature becomes 66.0°F, the track color
returns to red (see the figure below).
