An automated brewing vessel uses the following algorithm to adjust temperature and valve settings based on the system status entered by an operator:

2      IF status = 'boil' THEN
3          target_temp ← 100
4      ELSE IF status = 'mash' THEN
5          target_temp ← 65
6      ELSE IF status = 'ferment' THEN
7          glycol_valve ← 'open'
8      ELSE

10     ENDIF
11     FOR step ← 1 TO target_temp
12         IF step < 70 THEN

14         ELSE
15             ENGAGE_HEATER('high_power')
