Primo Precision Control Kit Large

Will this fit my Primo Oval Large?

Yes, this is the Oval Large kit. Primo lists a separate control kit for each size, so buying by the name in the title is the whole trick. An X-Large owner needs the X-Large kit and a Round owner needs the Round kit, and no amount of similarity between the grills changes that.

How is a control kit different from a wireless thermometer?

One measures, one manages. A wireless thermometer sends you readings so you can decide what to do about them, such as Primo Remote Wireless Grill Thermometer. A control kit takes the decision as well, working to keep the grill at the target you set. Many people end up running both, for different parts of the same cook.

Do I still need a heat deflector if I have a controller?

Yes, they do unrelated jobs. A deflector puts a physical barrier between the fire and the food, which is what makes the cooking indirect. A controller decides how hot the grill runs. Low and slow generally wants both: the barrier so nothing scorches, and the steady temperature so the cook lands where you planned.

What kind of cooking is this actually for?

Long ones. Brisket, pork shoulder, ribs, a turkey that needs hours rather than minutes. On those the enemy is drift, because a fire that creeps up while you sleep does damage you cannot undo in the morning. For steaks and burgers you are standing at the grill anyway and a controller adds very little.

Can I move the kit to another Primo later?

Treat it as belonging to the grill named in the title. The kits are listed one per size for a reason, so if you add a second Primo, plan on the second grill having its own rather than shuttling one between them. That is different from a thermometer, which travels wherever you cook.
