Hi,
I use the HM on my cabinet smoker (door instead of a lid) and during a cook, I send the lid open signal to cut the fan for a couple of minutes while I add meat / wrap, move around or take out meat.
Sometimes a door opening event is less than a minute, and other times it may be more, longer lid open events require more heat to recover back to cook temp.
Ignore the noisy "Fire" temp in grey, its not right.
A quick recovery is on the left (pulled out a brisket, pit dropped to ~112) and a slower recovery on the right (photo opp, wind blowing, moved a turkey, put the cleaned probe into a cooking pork loin.... temp dropped to like 87 degrees)
The recovery on the left did not require the fan to go to 100%, but the one on the right took 100% for about 3 minutes, then it backed off and increased again, then slowly started cutting the fan until the temp hit the target temp, then it really cut back (but still kept pushing!)
Did I trigger startup mode settings or something ?
This is my first run with a servo, and the servo is working a damper on the exhaust side.
My servo does not move much until the fan is at 0%... is that the way it is supposed to work? The temp continues to rise when the fan is at 0 once the damper turns to the closed position. There is some area open for the exhaust even when the damper is "closed".
Here are my settings:
I have a 2x4 air inlet (1-3/4" x 3-3/4 ID or 6.5 sq in.) and use three 3" exhaust vents with about 1/4" opening around the butterflies when closed. That is 2.15" area each, so ~6.4 sq inches of exhaust vent when closed.
Using the three vents, I can make the exhaust come out of the cabinet low, middle or high. The butterflys are tuned to let a little more air flow out of the bottom, because I am trying to use a reverse flow pattern inside the cabinet.
