Ring Led - Honeywell ComfortPoint Open CPO-PC400-W Manual

RING LED

The CPO-PC400-W/CPO-PC400-UW is built with a Ring LED to indicate the operational status of the controller.
When a controller restarts successfully, the Ring LED operates in the following pattern:
• Top half of the ring LED glows in red with high intensity.
• Two blinks with reduced delay between the blinks and subsequently stops glowing for a few milliseconds.
