Kettles & Pumps
The Brewmaster uses this browser screen to monitor and control the system.
The Status area is updated every second, and shows the temperatures of each kettle, the on/off state of the pumps and heating elements, the time remaining on the countdown timer, and the heating element power factor applied by the SSRs.
The Control area allows the Brewmaster to turn each pump on or off, set the heater parameters, turn on a heater, silence the alarm, or hit the "big red switch".
The Messages/Alerts area displays each action taken, and Alerts, such as when a setpoint temperature has been reached or the coundown timer has expired.
Alarms cause the screen to flash, and an audible alarm to sound. Normally, the alarm continues until silenced.
Finally, an "App" that does something really useful...
