Notes:
1. * AFC STATUS LED will be solid ON during this fault•
2. COMM LED (amber) will flash the number of communicating devices connected
3. BM LED should be ON Solid when power is applied
4. STATUS LED will flash once per second in Idle mode.
Once a thermostat demand is received, it will flash 1 time/100 CFM requested
5. UNIT LED (blue) will flash once every four seconds when communications are norma
