Efficiency With The Great Lakes Guardian Auto Draw Off System.

Your Great Lakes Guardian will diligently monitor the temperature in your stack so that you can maintain your heat within a target zone. This will help you maintain a nice even boil for great fuel savings.

The ADD FUEL/AIR status light on the Command Center tells you when to add more heat (factory preset is 980ºF). The HIGH LIMIT status light tells you when your evaporator is being run too hot (factory preset is 1500ºF). These temperature settings can be easily customized to suit your personal preferences.

To customize the ADD FUEL/AIR setting:
-Give the SET button on the Stack Temperature module one quick tap.  Then use the up and down arrow buttons to adjust the flashing digit.
-To make larger adjustments to temperature, use the left arrow button to move to other
digits. You can then adjust those digits with the up and down arrow buttons.
-Give the SET button a quick tap to return to the home screen.

To customize the HIGH LIMIT setting:
-Press and hold the SET button on the Stack Temperature module for 4 seconds. Then
use the up and down arrow buttons to adjust the flashing digit.
-To make larger adjustments to temperature, use the left arrow button to move to other
digits. You can then adjust those digits with the up and down arrow buttons.
-Press and hold the SET button for 4 seconds to return to the home screen OR after
30 seconds, the computer will automatically return to the home screen on its own

NOTE: If you quick tap the SET button, you will toggle to the LCY mode. Do NOT make changes to the LCY mode. It should always be zero. To return to the stack temperature module’s home screen from the LCY mode, hold SET for 4 seconds.
