Basic functions Options<br />
• 7-day time switch with holiday / special<br />
day program<br />
• Control of a 2-speed fan<br />
• Control of the <strong>supply</strong> <strong>air</strong> <strong>temperature</strong> via<br />
the heating coil valve <strong>and</strong> the cooling coil<br />
valve in sequence<br />

Engineering • A number of settings are plant-specific <strong>and</strong> may need adjusting after the initial commissioning of the<br />
<strong>control</strong>ler<br />
• The connection diagram does not show all plant interlocks but only those directly connected to the<br />
<strong>control</strong>ler or associated equipment<br />
