OPEN LID DETECT 
 
This feature will allow quick recovery to the setpoint temperature after the lid is opened. When the open lid is set to 

 (open lid yes), open lid detect is enabled. When the lid is opened, the temperature will drop. This can cause 

the blower to over-fire the coals and cause overshoot when the lid is shut. This mode detects when the pit’s lid is open and 
minimizes the blower running during that time. Some overshoot will always be present when the pit’s lid is opened and 

closed even if the blower is off, because it still introduces oxygen to the fire. The factory default is 

, so 

disable this feature if there are problems with excess air currents in the pit. To disable this feature, set it to 

 

(open lid no). To prevent false alarms, the alarm will not sound when the temperature drops and the lid is open. 
 
 
OPEN LID DETECT – OVERSHOOT ELIMINATOR 
When the open lid detect is enabled, the rate that the temperature rises in the pit will be limited, preventing over-firing. 
This will make a typical startup to a temperature of 250 degrees F take a minimum of 20 minutes and will help to 
eliminate startup overshoot.  
 
 

 

11. ADAPTIVE CONTROL STRATEGY 

The DigiQ’s Adaptive Control Strategy is designed to operate with a wide variety of pits by continually learning what the 
pit is doing and adapting to many factors such as outside air temperature, amount of charcoal, damper settings, etc. For the 
DigiQ to work properly and determine how to adapt, the temperature inside the pit cannot oscillate up and down and the 
lid must stay closed. If the lid is opened often, especially on startup, the control cannot be expected to maintain setpoint. If 
the lid is left closed for approximately 10-20 minutes, the temperature will become stable after the control adapts. If the 
lid has been shut for at least 20-30 minutes and the temperature is going up and down significantly (+/- 10 degrees or 
more), the fan damper needs to be closed more. The pit may run a few degrees high or low due to various conditions but 
the control will bring it back to the setpoint. Pit temperatures of 20 degrees high or low rarely have an effect on the quality 
of food. 
 
SNAP-TO SET POINT 
Air currents in your grill or smoker can make a sensitive and accurate instrument like the DigiQ read actual temperatures 
rapidly (ie: 223, 224, 223, 225, 224, 226, etc. when the pit temperature is set to 225°F). The DigiQ control is programmed 
to snap to the pit set point temperature when the pit is /- 5 degrees of the temperature set
