Flashing Indicators

Several situations or events are indicated in normal operation by blinking display indicators or segments in the display:

Flashing On Indicator : This means that the furnace is in the “Lighting” state waiting for either a 3 minute timeout to begin burning or for the furnace to reach the warm temperature whichever comes first.

Flashing Off Indicator : This indicates that the furnace is in the “Shutdown” state waiting for the OFF button, or for a 15 minute period after the furnace was turned off, or for the furnace to cool down, or for the door to be closed.

Flashing dash “-“ in Heat Range Display : This indicates that the furnace is in the normal run mode and is ramping from the current heat range setting to the target heat range setting. Once the ramp is complete, the “-“ will stop flashing. For ramping from heat range 1 to 3, the default time is 90 seconds between internal settings.

Flashing Automatic Mode Indicator : This indicates that the furnace is in normal operation and is running in the automatic mode. However, either the Draft Fan or Auxiliary setting is manually configured.

Flashing Draft Fan Setting Indicator : This indicates that the furnace is in normal operation and that the vacuum sensor detects a loss of pressure either because the door is open or because there is a negative pressure in the room with respect to the exhaust.

Flashing Heat Range Setting Indicator : This indicates that the furnace is in normal operation and that an overtemperature condition exists causing the fuel to stop.

Flashing Auger Delay Indicator : This indicates that the furnace is in normal operation and that the hopper lid is open.
