Create and edit a roast profile in Giesen Profiler 2

Create a reusable roast profile from scratch, or change the settings in an existing profile. You do not need a previous roast to create one.

A profile contains the settings and optional triggers you want to reuse. A roast is the record of one actual batch. Creating a profile does not create measured bean-temperature readings.

1 Choose your starting point

Use Create for a new profile, or search for an existing one. The example profile name will differ from yours.

Open Profiles. Choose one of these routes:

• Create a new profile: select Create. Enter the details below, then select Create in the dialog to open the editor.
• Edit an existing profile: search for it, open it and select Edit profile.

Use a name you can recognise later, such as Brazil Cerrado — 5 kg — trial 1. You can replace the automatic name when creating a profile.

2 Check the profile details

For a new profile, fill in the creation dialog. In an existing profile, open Editor → Details.

Enter or check Start Weight before Expected weight loss, then check End Weight. If you change the start weight later, check the estimate again. For example, a planned 5 kg batch with 15% loss gives an estimated end weight of 4.25 kg. This calculation is an example, not a target for your coffee.

In the creation dialog, check Use RPM against your roaster's drum-speed unit. In the editor, eligible models show Drum Speed Unit under Details, with Convert to RPM or Convert to Hz. Use the conversion controls when needed; do not enter an RPM number into a Hz field.

3 Set the starting values and timed changes

A new profile starts with default setpoints and an End Time of 15:00. These defaults are not a recommended recipe. Review every control before using the profile on a roaster.

Open Editor → Setpoints and select the control you want to change. The editor includes Air, Power, Pressure and Speed. Check the unit beside each control. The settings you can use depend on your machine.

1. Select a row in that control's timeline to edit it.
2. Check Time and Value. A time of 00:00 means the beginning of the profile; later times are elapsed roast time, not the clock time.
3. Select Save in the row's edit form.
4. To add a later change, select Add, enter its time and value, then select Add in the form.
5. Repeat for the other controls. Use Delete on an unwanted point, then check the remaining timeline.

For Power, select AUTO, OFF or ON as appropriate; ON allows a percentage value. Choose the mode your machine and recipe require. Use known settings for your roaster rather than copying the numbers from a screenshot.

Check the point at 00:00 for each control. It can be sent when the profile is loaded if Initialize setpoints on profile load is enabled. Saving the profile and loading it for playback are separate steps.

If an Overwrite setpoint prompt appears when adding a point at an occupied time, check both values before choosing Overwrite. Use Cancel if you want to keep the existing point.

4 Check events and optional triggers

Open Editor → Events → End Time, select the existing end entry, enter your planned duration and select Save in the form. Keep planned setpoint changes inside that duration. A setpoint exactly at End Time is not run as a normal timed change during playback.

Crack and Notes are timeline markers. A planned Crack marker does not detect first crack in a future roast. Monitor each batch and mark its actual first crack.

If you need a timed reminder or another action, open Triggers. Follow How to use triggers for the full setup. Review existing triggers when editing an older profile, even if you only changed one setpoint.

5 Save the complete profile

The Save button inside a point's form applies that point to your working profile. Use Save at the top right to save the complete profile.

• Save: creates the new profile or updates the existing one.
• Save and close: saves the profile and leaves the editor.
• Save as: saves a separate profile under a new name. Use this only when you want to keep the original version.

When making a variation, choose Save as before saving over the original. You do not need a duplicate for every roast.

Return to Profiles, find the profile and reopen it. Check its name, model, weights, timeline and triggers. If a save error appears, keep the app open and resolve it before leaving. Check the sync status before relying on the profile on another computer.

6 Use the profile for your next roast

Follow Use a saved roast profile to prepare, load it and choose Play as Reference or Play. Make edits between roasts. If the profile was already loaded, save your edits and load the saved profile again before your next roast.

A profile created from scratch has setpoints but no recorded bean-temperature curve. Play as Reference does not run those setpoints or triggers. If you want a measured reference curve first, follow Record your first roast.
