	PID (Proportional, integral and derivative) is the most used feedback control algorithm in the process control industry. Despite its age, its simplicity in terms of deployment and its efficiency on most of industrial processes allow this technique to still have a bright future. One of the biggest challenges in using PID control is to find its parameters, the so-called tuning of the controller. This may be a complex problem as it mostly depends on the dynamics of the process being controlled. In this paper we propose a tool that is able to provide the engineers a set of PID parameters in an automated way. Several auto-tuning methods, both in open and close loop, are selectable and others can be added as the tool is designed to be flexible. The tool is fully integrated in the UNICOS framework and can be used to tune multiple controllers at the same time.

	At CERN there are currently about 200 ventilation air handling units in production, used in many different applications, including building ventilation, pressurization of safe rooms, smoke extraction, pulsion/extraction of experimental areas (tunnel, cavern, etc), and the ventilation of the computing centre. The PLC applications which operate these installations are currently being revamped to a new framework (UNICOS CPC). This work began 3 years ago, and we are now in a position to standardize the development of these HVAC applications, in order to reduce the cost of initial development (including specification and coding), testing, and long-term maintenance of the code. In this paper the various improvements to the process with be discussed, and examples will be shown, which can thus help the community develop HVAC applications. Improvements include templates for the "Functional Analysis" specification document, standardized HVAC devices and templates for the PLC control logic, and automatically generated test documentation, to help during the Factory Acceptance Test (FAT) and Site Acceptance Test (SAT) processes.
