Mashing with Rims Temp Lag

[paganknight]

Ok I did a Mush run with my FrankinRIMS and was looking over my notes and the Temp / times look a bit off.

I had my Omega Controller set for a step mash On/Off. Havent figured out the PID settings yet
but the temps laged a bit
the ten segment run was
1. 95* for 10 min
2. ramp to 113* (time to temp about 5 min)
3. hold for 10 min
4. ramp to 135* ( time to temp 8 min )
5. hold for 15 min
6. ramp to 143* ( time to temp 10 min )
7. hold for 30 min
8. ramp to 154* ( time to Temp 12 mins )
9. hold for 60 min
10. ramp to 168* mash out And Sparge

I noted that the ramp times were a bit long. Should I ajust the hold temps a bit shorter or get a bigger RIMS tube or go to SRIMS
with only water I get a 18* rise in 4.5 min. the RIMS tube i use I think is 1500 watt 110v
I don't think my Efficiency is up to par. BeerTools but my OG at 1.060 but i only got 1.052 want to do better but not sure if i can. I malt my own grain so that plays a big part there too.

Increase P or I a bit.

Increase what ?

Increase what ?

The Proportional or Integral control parameters. They apply a control force either proportional to the error (between set value and actual temp) or the integral of the error, and increasing these decreases the time it takes to reach the set value.

Ok that must be for the PID part of the controller I was not useing that just On/Off. So to increse the Ramp I guss i need to get a bigger RIMS Tube like a 2500 or maybe go to 220v.
