5. Go down to the line for Boiler Name to change
the name of the control. In this example, we are
working with the Primary control on Boiler 1,
so the name here should be “Boiler 1 Primary.”
To change the entry, press on the line for Boiler
Name. The system will present the keyboard
screen. Use the “BS” (BackSpace) key to erase
the existing name. Enter the new name, then
press OK.
6. Now you can rename the other control on
Boiler 1 – the Secondary control. Press the
Home button in the top left-hand corner to
go back to the Home screen which shows the
different controls (Fig. 53).
7. This time, press the icon for the Secondary
control. Repeat steps 1 through 5. Change the
name to “Boiler 1 Secondary.”
8. Go to the Operator Interface for the next boiler
in the system. Repeat steps 1 through 7 for
each of the controllers on that boiler. Be sure
the names you enter are correct – each name
should indicate the Boiler number and whether
the control will operate as the Primary or
Secondary.
9. Repeat the process for any other boilers in the
system.
Job C – make one Control the lead/lag
master
(This is an individual function – do this once for the control that
will act as the Lead/Lag Master. Use the Operator Interface on
Boiler 1.)
The Lead/Lag control system uses one controller as
the Lead/Lag Master. This controller supervises the
operation of the other controllers, and they all operate
together as part of the Lead/Lag system. There is
only one Lead/Lag Master in the system. Usually,
the controller used for this is the Primary controller
on Boiler 1. (Other controls in the system can be set
as the Lead/Lag Master, but we do not recommend
this because it may complicate troubleshooting and
technical support questions.)
The controller used as the Lead/Lag Master will also
do a second job, operating as Slave 1 in the Lead/
Lag system. A single controller performs both of
these functions. When it arrives from the factory, the
controller used for this should already be set up as a
slave – we will check that in a moment. For now, we
will just concentrate on enabling the Master function.
1. From the Home screen, press the View Lead
Lag button. See Fig. 57.
