Abstract

Intended as a guide to the selection and application of controls for various systems, with the necessary theoretical background to reinforce the practical proposals. Control requirements must be considered from the very inception of the design. Failure to do this may result in an uncontrollable system. The term 'controls' in the design of building services, and particularly HVAC systems, is often restricted to the automatic thermostatic controls. However, in modern buildings it applies far more widely and the design process must consider the interface of these controls with such elements as lighting, fire/smoke alarms, security, etc. It is normal practice to adopt dry resultant temperatures as the standard parameter for design temperature. However, in terms of automatic controls, temperature sensors provided by the manufacturers are still mainly related to dry-bulb air temperature scales and this Applications Manual uses dry-bulb temperature settings, unless otherwise specified, for consistency with the controls industry.
