Fermentation Temperature Control

Briefing

Controls the temperature of a fermentation vessel using a cooling jacket valve (0-100% output) and an agitator. The jacket valve opens proportionally to the temperature error (TEMP - SETPOINT). When deviation exceeds ±2°C, an alarm is raised. The physics module simulates the vessel temperature responding to the jacket cooling.

Objectives

• JACKET_VALVE_CMD (0-100 REAL) opens proportionally to (VESSEL_TEMP - SETPOINT)
• AGITATOR runs whenever FERMENTATION_ACTIVE_LAMP is on
• FERMENTATION_ACTIVE_LAMP on while running with no alarm
• Deviation > +2°C above setpoint latches alarm; deviation < -2°C also latches alarm
• Alarm clears when temperature returns within ±1°C of setpoint

I/O Table

Your program will be tested against:

All test cases run automatically when you submit. Assertions are hidden until you pass.

1. #1AGITATOR and FERMENTATION_ACTIVE_LAMP on when running

   Starting fermentation turns on both the agitator and the active lamp

2. #2JACKET_VALVE_CMD > 0 when vessel is above setpoint

   Physics starts vessel warm; valve should open proportionally

3. #3STOP_PB de-activates fermentation

   Pressing stop turns off agitator and active lamp
