Yet another PID question...

yes thx i was understood but didnt explain enough.

Okay. Glad you got it.

on the circonstances you mentionned i will use a cold smoke set up (outside box )for my smoke gen heat and a pid for the cabinet.

I was going to make a mention of the cold smoke box, but didn't want to throw another curve at you, if you hadn't been understanding the other stuff. Now that you have all that figured out, when are you installing the ABS (Automatic Beverage Server)?

Have a good one.

sorry i dont drink lol! unless i didnt understood your joke :D

You understood it....but beverages can mean water, pop (soda), and tea/lemonade as well. :D

if i asked everything about pid its beacause i fond a couple pre wire on ebay and its seems to be the best for preheating the smoker at a specific temp before puting the food inside. about 45$. Since i already own a maverick thermometer, it will be easier to cook perfectly. Like habs bacon, mtl smoked meat, jerky etc

hey wildcat one last question...What is diferancial.( for pid of course) it says ajustable from 1 to 30 degree. If i want my pid to be accurate at +-1 degree should i set at 1 differencial? Sorry never seen it before.

On my PID, there is a way to set the differential. Basically, if you can determine exactly what the true cabinet temperature is from another reliable source and the PID does not have the same reading, then you can use this feature to correct the PID.

Ok thx i undertood it will adjust in function of the sg. So if the sg is on it will say 200 with it and when im done with the sg it will higher the heat beacause i closed the sg thank you now i know.

toker1313,

Correct. The PID is regulating what it can to reach a setpoint. If the SG is on, it is providing some heat and the box heating element needs to provide less to reach a certain temperature. Turn the SG off, and the box heating element will be asked to provide more heat to maintain the setpoint temperature.

I think Tim and Wild and Sparcs nailed this for ya....And from my small experince you defintely want a PID!!

The differintial setpoint is the number of degrees away from set point the PID will start to take action. If set too low like 1 degree it will act as a on-off switch. if set too high it will take way too long to dial in. the PID should learn this also.

Toker · May 22, 2008, 11:58:43 AM

So at wich diferential degree should i set it to be more even temp?

Hooked on smoke · May 23, 2008, 04:58:11 AM

The PID should learn this as it goes along, but a good starting point would be about 5 degrees. That way as it gets close to temp it will start to cut back and not over shoot. If it does over shoot by more than a few degrees, increase setting a dgree at a time. If it never gets to temp take one off.
