Output :

Heating$/$Cooling Control $($HCC$)$: Activates the reversible heating$/$cooling system $(HCC=0$ for heating mode and $HCC=1$ for cooling mode$).$

Design Specifications:

The temperature is too high, and agitation is active, activate the reversible heating$/$cooling system $)=(1$ to switch to cooling mode. $4()$

If the temperature is too low and agitation is inactive or the bioreactor is not in the production phase, activate the reversible heating$/$cooling system $)=(0$ to switch to heating mode. $4(0)$

If the temperature is high and the oxygen level is low, indicating suboptimal conditions for biological processes, activate the reversible heating$/$cooling system $)=(1$ to switch to cooling mode and maintain the temperature within the optimal range. $2()$

When the bioreactor experiences sudden temperature fluctuations and the production phase is active, suggesting a critical stage in the production process, activate the reversible heating$/$cooling system $)=(1(1$
