I am working on the heating chamber, where heating/cooling is regulated by closed-loop control (PID). Heating/Cooling polarity is set/reset depending on the difference between temperature reached and desired temperature.
Power to the Heating/Cooling module and Heating/Cooling Polarity are digital outputs.
I want to linearize the system in order to find the best P;I;D gains. Any suggestions how I can linearize the system?

You could use the PID Tuner app. When it opens, it will first linearize your model. See here.
