Thermostatic control - Short description

Short Description

This control function describes a room or building thermostat, i.e. a function which regulates energy suppty into eg. a space heating radiator with the aim of keeping the temperature in the room or buitding consta nt at or neara desired value (setpoint).

The control function is described as having a single input and single output; i.e. buildings with multiple temperature controlled sub-velumes must either use multiple controllers, or be modelied as e singie, lumped volume.
