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. 52).
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 Touch Screen 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 Touch
Screen 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.
Start at the 'home' screen. See Fig. 56.

Screen (Fig. 58).

4.
This screen shows the most important settings
for the Lead/Lag system. The settings can be
changed from this screen. Some of them will
require passwords.
We will enter all of the Lead/Lag control values
in a moment. For now, just press on the line
for Master Enable. Change the setting to
Enable.
