EZboil DSPR320A for Boiling, Step Mashing, and Low Oxygen (LODO) Brewing, Advanced Model

Description

• No more PID tuning!
• Digital power regulator to automate step-mashing, low-oxygen brewing (LODO), and whirlpool after boiling
• Flexible mashing step and boiling step programming.
• Rotary knob design. Easier to make changes on-the-fly. Advanced alarm relay programming functions.

DSPR320A is the latest model of Aubers EZboil series controllers. It is a digital power regulator designed for home brewers who want to automate step-mashing, low-oxygen brewing (LODO), and whirlpool after boiling. This model, DSPR320A, is step-up from EZboil DSPR310D with a lot of newly added features including:

1) More flexibility in Mash and Boil programming. In DSPR320A, the brewer can program boil steps in Mash Mode and can program mash steps in Boil Mode, which are are not allowed in DSPR310D. The flexibility in programming enables the brewer to implement low oxygen brewing recipes and whirlpool method automatically.
2) More relay functions are added. In DSPR320A different sections within a program, e.g. ramp-up sections, ramp-down sections, and timed steps, are now clearly defined. A relay can be assigned to synchronize with a particular type of section in particular steps. For example, the brewer can assign the relay to drive a cooling pump to cool the wort at a desired step.
3) Easier to make changes on-the-fly. The user can change set temperature, step timer, and jump steps while the controller is running the program.
4) Temperature deviation alarms are added.

Note:
1. The temperature sensor is not included. This controller can read PT100 RTD temperature sensor.
2. This unit needs to be used with SSR (not included).
