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 heater is in the “Start Up” awaiting for the ignition procedure to complete.
Flashing Off Indicator: This indicates that the heater is in the “Shutdown” state waiting for the OFF button, or for a 15 minute period after the heater was turned off, or for the heater to cool down, or for the door to be closed.
Flashing dash in Heat Range Display: This indicates that the heater 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 5, the default time is 12 minutes (with a 90 second ramp time).
Flashing heat range value in “Heat Range” display: For example, if the display is showing
Flashing Automatic Mode Indicator: This indicates that the heater 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 heater 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 Aux Indicator: This indicates that the igniter is on during the lighting stage.
Quick (changes twice per second) Flashing Heat Range Setting Indicator : This indicates that the heater is in normal operation and that an over temperature condition exists causing the fuel to stop.
Slow (changes once per second) Flashing Heat Range Setting Indicator : This indicates that the heater is in a cutback condition in an attempt to prevent an over temperature shutdown.
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.
