What does the Overtemp light on the control panel indicate?
The Overtemp Light (item 4 on the control panel) is a warning indicator on the front of the CST 280. While the manual identifies it as a labeled component on the control panel diagram, it signals that the machine has reached an over-temperature condition. The Fan-On-Demand cooling system operates only when needed to help prevent overheating. (Page 2)
