The set temperature and Gas control (Giesen machines only)

This article highlights what you need to consider when using set temperature and Gas control on Giesen machines.

 

The following article and its screenshots refer to the Roasting Intelligence (RI5). 

In case you previously used the Roasting Intelligence (RI4) we kindly invite you to check the newly improved features of RI5.

The set temperature and Gas control on the Giesen machines

Please note the following differences in the terminology between Giesen and Cropster:

What Giesen refers to as air temperature is tracked as exhaust temperature by the Roasting Intelligence (RI). The burner power percentage is the gas percentage in Cropster.

When using the Gas replay and the exhaust temperature (air temperature) reaches the temperature setpoint, the Giesen machine will take over the gas input and overwrite scheduled gas changes to prevent the exhaust temperature to go beyond the setpoint. This may cause deviations in the Roasting Intelligence (RI).

 To prevent the Giesen machine from interfering with your profiles, we recommend checking the maximum exhaust value on your profile and set the set temperature slightly higher. 

Using Gas control in the Roasting Intelligence (RI)

To use Gas control in Roasting Intelligence (RI), you need to use the manual setting for the burner (gas) power. 

By following the steps below you can use the manual setting in the Roasting Intelligence (RI):

  1. Log into the Roasting Intelligence (RI).
  2. Navigate to the Controls on the bottom of the right side of the screen. 
  3. Select Show gas control
  4. The Auto toggle button will appear on the top of the Gas control slider.
  5. Toggle the button off to use gas control in Roasting Intelligence (RI).

 If you previously used RI4 you might have already noticed the change regarding the +/- signs of the Gas control bar which we would also like to draw attention to: In RI5 the -/+ buttons have a reversed position. The - is on the top left and the + is on the top right side of the Gas control bar. 


When the burner (gas) is set to manual, you are able to raise or reduce the temperature up to the level that is defined as the set temperature.
💡 For example, if the temperature setpoint is on the Giesen is set to 220 degrees and the burner (gas) is set to manual in the Roasting Intelligence (RI), you will be able to manipulate the exhaust temperature (air temperature) at any levels up to 220 degrees. Since this is the set temperature, Giesen will not allow you to raise the temperature above this value. The maximum value is up to 250 degrees.

If the Auto toggle is enabled, the auto burner (gas) setting will take over and Giesen will try to reach the temperature setpoint immediately.

Slider control settings


Once you enable the setting to reset the profile slider control settings, you need to keep the following detail in mind:

The setting for resetting the slider controls uses the first level of Gas control a a reference. 
💡 For example, if you select a reference roast for your profile where the roast started with the Auto toggle enabled even if it was disabled at a later point, the slider controls will still use the first level of Gas control as a reference. So in this case, the Auto toggle will be enabled at the end of the roast. 

To avoid this issue, we recommend you replace the reference roast for this profile with a roast that does not start with the Auto toggle button enabled.

You have two options to choose from in this case:

  1. You can select a reference roast from existing roasts.
  2. You can create a new roast where the Auto toggle button was disabled at the start and set it as a reference for your profile.
