3 Predictive heating controller
3.1 Overview
Predictive heating control considers a building's total performance and controls the
plant to achieve the required comfort while lowering energy consumption. To do
this, predictive heating control uses a building model determining the future
(optimized) flow temperature setpoint profile by means of numeric optimization.
This process includes outside temperature forecasting as well as the future course
of the room temperature setpoint. As an option, predictive heating control can
continuously adapt its building model parameter values by processing the
measured values for flow, outside and room temperature.
The algorithm for predictive heating control is a model-based, predictive, and
adaptive control.
The algorithm represents a great alternative to classic, outside-temperature-
controlled heating control based on:
– Heating curve
– Heating limit switch
– Switch-on/switch-off optimization
