Controllers

The Controllers page (see Fig. 111) is displayed by pressing
the CONTROLLERS button on the Setup page (see Fig. 94).
This button isn't available in System mode. On the Controllers
page, the user can manually assign UDC controllers to
specific burner/boiler systems (Switchable mode only) and to
search for available UDC controllers on the COM2 port. For
Local S7999B mode the found UDC controllers are
automatically assigned to the Local S7999B. The Refresh
button starts the search procedure.
NOTE: This search locates attached UDC controllers in a
fast search rather than the slower background
search.

To assign a UDC controller to a burner/boiler system:

1. Select a burner/boiler system button to enter Modbus™
address of the system you want to assign the UDC con-
troller to.
2. Select the controller address button to enter Modbus™
address of the UDC controller or select one of the UDC
controllers in the Not Attached list.
3. Press the "Add Controller" button to assign the UDC
controller.
4. If the UDC controller is already assigned to another
burner/boiler system, a warning dialog box asks you to
confirm the change in assignment from the old system
to the new one.

To delete a UDC controller assignment:

1. Select the burner/boiler system button to enter Mod-
bus™ address of the system.
2. Select the UDC controller address button to enter Mod-
bus™ address of the UDC controller, or select the UDC
controller in the Assigned list.
3. Press the "Delete" button.
The UDC controller becomes unassigned and moves from the
Assigned list to the Not Attached list.
NOTE: For Local S7999B mode the burner/boiler system
address isn't entered because only assignments for
its own system are permitted. Deleting UDC assign-
ments in Local mode is only temporary, because the
next time the UDC is found, it will be assigned auto-
matically.
