# Mashtun

The "Mashtun" is the right type for mashing if you stirr your mash.

This device type also supports automatic **calibration**. Read [Calibration](/using-bricks/equipment/calibration.md) to find out, what the huge benefits of calibrating your device are.

### Interfaces

It offers three different interface types:

* Electrical switches for heating (required)
* Electrical switches for circulation, i.e., to control a pump or stirring using the software (optional)
* Temperature sensors for wort temperature (required)

### Settings of a mashtun

You can change the following settings:

* "When to turn the circulation on":
  * "Always on": The stirring will be always on. Only requirement: The recipe step (in Automatic) or toggle (manual) must have circulation to be set to "turned on".
  * "Only during and after heating": This will only turn the circulation on when the heating is turned on and a configurable amount of time (in minutes) after heating was turned off.
  * "Only when heating": Like the last option, only that circulation will be turned off immediately after heating is stopped without any delay.
