Display 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 stove is in the “Start Up” state waiting for either a 3 minute timeout to begin burning or for the stove to reach the warm temperature whichever comes first.
Flashing Off Indicator: This indicates that the stove is in the “Shutdown” state waiting for the OFF button, or for a 15 minute period after the stove was turned off, or for the stove to cool down, or for the door to be closed.
Flashing dash in Heat Range Display: This indicates that the stove 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 dash will stop flashing. For ramping from heat range 1 to 9, the default time is 12 minutes (with a 90 second ramp time).
Flashing Automatic Mode Indicator: This indicates that the stove 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 stove 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.
Factory Defaults
To return the control to its original factory default settings, press and hold the AUX UP and AUX DOWN buttons together for three seconds.
