Set up induction hob GGM IDS
Creating the mash brew kettle
In the first section Maischeplan, the MashSud boiler is created using the gear at the top right.
Configuring a hob
First, a hob must be configured. A GGM IDS induction hob is set up in this basic setup.
The first setting concerns the IDS type, where IDS1 or IDS2 can be selected. This is followed by three control parameters:
PIN white [relay] - Default: D7
PIN yellow [Command] - Default: D6
PIN blue [Interrupt] - Default: - (unused) or D5
These GPIOs (D5, D6 and D7) are preconfigured for the GGM IDS connection cable with JST-HX socket or the screw terminal block.
Next, a temperature sensor must be assigned to the MashBud kettle. The selection is made from a list of sensors that have already been set up. In this basic setup, only the sensor Sensor IDS2 is present, which is selected accordingly.
Note: A temperature sensor must be permanently assigned to a hob. The sensor value is referred to as the actual temperature or current temperature and is continuously compared with the rest temperature (target temperature) during the mashing process.
The parameters in the "Temperature control" tab are explained in detail in the "All parameters" section. For the basic setup, the default values are initially adopted.
Setting up the PID controller
After the basic configuration, the PID controller must be set up in the PID Manager tab. The PID controller automatically calculates the power required for the hob to bring the mash temperature (actual temperature) to the rest temperature. A precise PID configuration ensures that the rest temperature remains constant over the entire rest period.
The PID controller is set with two parameters:
Ku (ultimate gain) – gain factor
Pu (ultimate period) – period length
The PID parameters P, I and D are calculated from these two values. These parameters are individual for each brewing system and are determined using the AutoTune process. The AutoTune process is described in detail in the "AutoTune step by step" section.
The following values for Ku and Pu are entered for this basic setup. The PID tuning rule IDS PID Mode is then selected:
As soon as the values for Ku and Pu are entered, the selected PID algorithm automatically determines the three values P, I and D. A detailed explanation of all parameters will follow later.
Starting values for different boiler sizes
For a 36L kettle with around 20L mash volume:
For a 70L kettle with over 50L mash volume:
Completion of basic configuration
After saving the settings, the basic configuration is complete. You can now brew with a temperature sensor and a mash brew kettle.
Note: A mash plan is also required for the actual brewing process.
