How energy efficiency is improved
Enables the implementation of individually optimised controls for maximum efficiency in pneumatic installations.
Areas of application
Room-temperature control (P) with supply-air temperature as auxiliary control loop (PI) in ventilation and air-conditioning equipment. Pneumatic control of temperature, pressure, differential pressure, humidity and flow rate in combination with appropriate transducers.
Properties
