# Calibration

Nailing temperatures especially during mashing is crucial. By default, temperature controllers turn off the relais (the heating) when the target temperature is reached. This inevitably leads to temperature overshoots. Our software is already a little bit smarter by default and turns off the heating **before** the target temperature is reached. 👌

It get's even better: By hitting the <img src="/files/-MefiX77fQCX9oc2IkPW" alt="" data-size="original"> button, the BierBot Bricks software **automatically** learns how your system behaves to **minimize** future overshoots. 👌👌👌

To calibrate your device, set it up like you would for a normal brew. This means, e.g.

* Fill it up with water (just skip the fermentables).
* Install your stirring equipment (pump in BIAB systems).

It'll take about 60 minutes to finish the calibration. After that, your PDI and other device settings are automatically calculated for you. If you want, you can still adjust the automatically inferred PDI settings afterwards (read about it here [PDI control settings](/using-bricks/equipment/pdi-control-settings.md)).
