Open Ardbir - Open source platform for brewing process control and automation

Anyone know can a manual pwm control be connected to the board i.e a hardware dial. Cant see owt in the manuals

[Sorcerers Apprentice]

There's already a pwm option in the menu, however as others have mentioned support info is sparse.

[darren996]

Ah yeah, i know its there in software throigh the menu, but it would be nice to have a dial control on the box..cheers

When it's boiling you have the buttons (up/down or 1&2 with flat strip) to decrease/increase % for the PWM.



Way handier & easier to control than rotary dial.

Yeah a lot handier, thanks

The software is open source build by a number of different people. It is a bit difficult to do software support. You have to find it in forums etc.

Is it possible to operate as a PID controller and a PWM at the same time? I was hoping that I could throttle back the power to the RIMS heater using PWM while at the same time using the PID to control the mash temperature ?

In manual mode the PID switches to PWM when to set temperature is reached. And this set temperature is also within the boiling range. The PID / PWM output is send to the heat connection. You can find it in the manual
I don't think it is possible the way you want it.

Thanks McMelloW I'll send an email to Davide to see if he has any ideas

[darren996]

How are ye fellow ardbir builders going to mount the temp probe in your kettles?

[McMelloW]

Thanks McMelloW I'll send an email to Davide to see if he has any ideas

I think you are talking about a multi vessel system. The Open Ardbir is for a single vessel system

In the Setup (hold for right button (4) for 4-5 secs)



> PID-PWM



> (7th click/step) Heat in Boil %, this will allow you to throttle back the power to the RIMS heater.



It then runs the PID as normal in your mash phase.

When you go to boil, you may need to increase power up for kettle elements to 100% to get to boil (& reduce if necessary to keep rolling boil)

Thanks pob my intention is to ignore the pump outlet but switch the different elements via a selector switch and possibly use a stand alone PID for the HLT. This will allow me to heat the sparge seperately.

Ps here's the response from Ardbir


Hi, I am Max, the code man.
The PWM control  is used on Boil, in the mash is used the PID control only around 4°C on SetPoint.
You can try to reduce the kP value on PID control or change the output value on the code.

Hi folks i am waiting on neutrik connectors, anyone know what size hole to drill for them
