Zone Controller


Convert microblock

The Zone Controller microblock is designed to provide stable temperature control of a single-zone heating and cooling system using two modified PID control loops.

The two PID loops (a direct acting loop for the cooling output and a reverse acting loop for the heating output) are non-linear. This allows for fine-tuning corrections when the system is near setpoint and larger corrections when the setpoint or the load changes and the system needs to adjust quickly.

The algorithm also makes adjustments to optimize performance whenever the system is operating in the night setback or morning start-up modes.
