Package description<br />

The heat<strong>in</strong>g control bench is used to study a central heat<strong>in</strong>g system with<br />

control loops.<br />

The operational part represents a reduced central heat<strong>in</strong>g system compris<strong>in</strong>g:<br />

@ a 3-way motorised valve<br />

@ a variable speed pump (circulator)<br />

@ a heat exchanger (fan-cooled heats<strong>in</strong>k).<br />

The control part <strong>in</strong>cludes a Premium PLC which provides all <strong>the</strong> control<br />

operations, an Altivar variable speed drive and all <strong>the</strong> associated electrical<br />

protection elements.<br />

A graphic operator <strong>in</strong>terface term<strong>in</strong>al is used to control and monitor <strong>the</strong> system.<br />

An E<strong>the</strong>rnet connection allows you to connect a computer and control<br />

supervision remotely.<br />

The system is configured to use one of <strong>the</strong> three follow<strong>in</strong>g control loops:<br />

@ PID loop: central heat<strong>in</strong>g with <strong>in</strong>ternal temperature sensor<br />

(act<strong>in</strong>g on <strong>the</strong> water flow)<br />

@ PID loop + servo: central heat<strong>in</strong>g with <strong>in</strong>ternal temperature sensor<br />

(act<strong>in</strong>g on <strong>the</strong> three-way valve)<br />

@ PID loop: central heat<strong>in</strong>g with external temperature sensor and water<br />

ratio (act<strong>in</strong>g on <strong>the</strong> three-way valve).<br />

The system can be disturbed us<strong>in</strong>g a set of three motorised fans of variable<br />

speed.<br />
