CraftBeerPi test

Setup:

• Mash Tun. Beerbrew 30 with bypass on internal controller 2,5Kw heat. Only 5L water to reduce heating time. (and overshoot temp fluctuate extra)
• HERMS with 2Kw (Tube on right side.)
• Sparge water in back. 2,5Kw
• Rasperry pi 3. Craftbeerpi 2.2.
• GUI (Graphic User Interface) on LCD monitor or command line. With Command Line (CL) is Safari browser used to control CBP.

Sensors:

1. Wort out from HERMS.
2. Wort from mash tun in to HERMS
3. Water temperatur in HERMS
4. Temperature in mash tun.
5. Temperature in sparge water.

Heaters:

6. HERMS 2Kw
7. Mash tun 2,5Kw.
8. Sparge water 2,5Kw.

Wish:

I want to use heater in both mash tun and HERMS to rise temperature fast. And use only HERMS to maintain temperature. So if mash tun could run parallel to 1 degree below setpoint to HERMS would be perfect. (I do this manually today)

Testing different setup.

Notes

1. Test #4. Turned on RasperryPi and waited 1 hour before I used it. Everything hang. Off and on with power to solve this.
2. Test #6. 2 Kettles with PID did not work. It seems that both heaters tried to reach the highest setpoint.
