RUTE. BOILERS AND VOLUME WATER HEATERS, 1,000 & 1,200 MBTU/h
Job D - Disable the Lead/Lag Master
Function on the Lead/Lag Slaves
(This is an individual function – do this for each of the
controls, except the one used as the Lead/Lag Master.
Use the separate Touch Screen on each boiler.)
At the beginning of this section, we described
the Master and Slave arrangement used with the
Lead/Lag system. In the previous section, we
explained how to set up one controller as the Lead/
Lag Master. As we said, the controller used as the
Master (usually the Primary controller for Boiler 1)
also serves as a Slave (usually Slave 1). A single
controller performs both functions.
When the controllers arrive from the Bradford White
factory, they will all be configured as slaves. Your
job in this step is to disable the Lead/Lag Master
function on each of the controls, except for the one
control that will be used as the Lead/Lag Master –
usually the Primary control on Boiler 1.
1.
From the 'home' screen (Fig. 59), press
the icon for the controller you want to work
with. In this example, we will start with the
Secondary controller for Boiler 1, and make
sure this is not set up as a Master.

2.
The system will take you to the Status
Summary screen.

3.
To disable the Master function on this
controller, press the Configure button. Figure
61 shows the Configuration screen.

4.
Scroll down through the list until you find the
line for LL Master Configuration. See Fig. 62.

Press on the line for Master Enable. The
system will go to a separate screen and ask
you to login using a password. Enter the
password (see Section 8.2), return to the
Master Configuration screen, then press the
line for Master Enable again. Change the
entry to Disabled.
Don't change any of the other entries on this
screen.
5.
At this point, you have disabled the Master
function on one of the controllers. You will
need to repeat the process for each of the
other controllers in the system (except the
Primary Controller on Boiler 1).
Go to the Touch Screen on the next boiler.
Repeat steps 1 through 4 for the first controller
on that boiler.
6.
Repeat the steps listed above for each of the
other controllers on the system. Disable the
Master function on each of them.
