Perhaps this info will help you program the PID portion of the controller. First the Proportion calc, then the Integral calc, then the Derivative Calc, then how they are summed, and finally, an explanation of the variables involved. Gain, TI, and TD are the parameter adjusted to tune the PID loop. Take out the TD_LAG if you don't want to include lag. SP is the Setpoint (target temperature in this case) and PV is the Process Variable (the measured temperature in this case).
