System information

Return Fan
This element represents a return fan, which pumps return air through an HVAC system.
Figure 176: Return Fan
The Return Fan element has the following runtime characteristics:
• When the element is bound to a Metasys item, the attached Advanced Value Boxes display all of their functionality.
For information about Advanced Value Box functionality, see Advanced Value Box.
• The color of the fan blades reflects the current value of the Return Fan Status item (for example, stopped or
running) as defined by the Fan Status section within Metasys system preferences. By default, green indicates
a running fan and red a stopped fan. However, if the status of the item is not normal (for example, offline), the
color of the fan blades reflects the status of the item as defined by the Status Colors section within Metasys
system preferences. In other words, the status color for a non-normal item supersedes the fan status color.
• When the value of the Status binding is:
- Off - the fan blades do not spin.
- On - the fan blades spin.
