FIELD: information technology.SUBSTANCE: actuator for a heating, ventilating, and air conditioning (HVAC) system comprises a stored model definition defining an HVAC control application, and an element library including a plurality of stored model elements and controller modules, having instructions for controlling a processor of the actuator. The controller modules include model elements and are configured to control the sequential order of their execution. The controller modules are further configured to propagate any external data input to their model elements prior to executing their first model element and propagate any data output to external components after executing their last model element. The controller modules are instantiated in different threads of execution, so that data is interchanged asynchronously between instantiated controller modules and neither temporal dependencies nor change of value links are imposed on components of the control application.EFFECT: high accuracy of control.15 cl, 9 dwg |
