4. PROBES
The probes provided with the DigiQ are precision stainless steel thermocouples. The thermocouple wires have an armor
braid with moisture and smoke resistant Teflon insulation that is rated for steady-state temperatures up to 500 degrees F.
The user can pass these thin wires under the lid of the grill or through a small hole without creating a large gap which
would allow air to get through (air intrusion). Be careful not to kink these wires or let them come in contact with flames.
These probes are user-replaceable and are available at www.bbqguru.com
;
we recommend having a spare set for
unforeseen emergencies.
Important Note:
Be sure to fully insert your probes into the control. Push the plug into the receptacle until you feel
and hear it snap in place. If you do not plug the probes in securely, you may experience sporadic temperature readings
and the DigiQ DX2 will not control your cooker accurately. The temperature may also read low, causing your cooker to
get excessively hot.
Important Note:
The pit probe must be placed in the pit for proper temperature regulation. If the pit probe is not
located in the pit, proper control will not take place. This can cause the blower to run constantly causing your pit to
become excessively hot.
Important Note:
The Big Green Egg and other ceramic grills present a special-case situation that can lead to early
probe failure.
If you use the plate setter heat diffuser, you need to run the probe cables over one of the ceramic legs. The heat coming
up through the gaps is intense and focused, and if the cable is exposed to this heat, it “bakes” and begins to break down
much more quickly than usual.
Even if you do not use the plate setter, any heat or flame “event” inside your Egg can send a blast of heat – even flames –
up the inside of the smoker, sometimes ruining a probe instantly. In this case, we recommend placing a disposable pan
inside the Egg to create a “safe zone” for your probes. This can be done with or without the place setter.
It is the very efficiency and insulation that makes the ceramic cookers so versatile that makes special steps necessary.
Follow these steps and you can experience the 2-3 year probe life that is common with other types of smokers.
4.1. FOOD PROBE
If the food probe will not be used, it should be unplugged before applying power to the DigiQ, not during operation. This
will allow the DigiQ time to configure its alarm operation to prevent false food alarms. The food probe can also be left
plugged in, but not inserted into the food.
