Hydronic “Boiler # Configuration” Screens
The Boiler Configuration Screens are used to independently setup each hydronic
boiler in the loop. The Hydronic Boiler Configuration screen allows the user to
change the mode of each hydronic boiler in the loop, along with providing a
manual control option. See Figure 6.
