6.1 Continuous Control with Virtual Master
The Virtual Master function maintains smooth control if group communication is compromised. In these operating
configurations, a lead (master) unit is in charge of component staging in teamwork mode, unit staging, and stand-by
rotation. If the lead unit gets disconnected, iCOM automatically assigns a virtual master, which assumes the responsibilities
of the lead unit until communication is restored.
6.2 Teamwork Modes
When iCOM controlled thermal management units are connected to a network in a group or team, use teamwork to
optimize performance and efficiency depending on the mode chose and its application.
In a panel with Status content, the Teamwork mode icon indicates the mode selected, Figure 6.1 on the next page.
Touching the icon displays the Teamwork dialog from which you can access the teamwork control settings.
