Fig. 73 – Flap Valve Configuration Screen
Notice that there are two items on this screen.
Controller ID -
This is the ID number of the flap valve
associated with this controller. (We will set
the ID number for the other controller in this
boiler in a moment.)
Number of controllers -
This is the total number of controllers
in the whole system. (For example, in a
system with four boilers, there will be eight
controllers.) See Table 14.
You need to set both of these values on the Flap
Valve Configuration screen for each controller
in the system.
table 14 – number of Controls
Number of
boilers
Number of
controls

3 6
4 8
For example, if your system has three boilers,
there would be a total of six controllers (two
for each boiler), so you would enter “6” for
Number of Controls.
5. Because you are changing a parameter that
is related to safety, the system will present a
warning that looks like this:
fig. 74 – Parameter Safety Warning
Press OK to continue. The system will ask you
to login before you make a change.
Note that any changes you make will apply
only to one controller – the controller you have
already selected. If you want the same change
to apply to other controllers, you must change
each of them separately.
Once you change one of these safety-related
parameters, you must finish the verification
process, or the control system will not let the
boiler operate
. Each control in a boiler must
be verified separately.
6. Press again on the line for Controller ID. Table
15 shows how the Primary and Secondary
controls should be numbered for each of the
boilers.
Boiler 1 Boiler 2 Boiler 3 Boiler 4
Primary control 1 3 5 7
Secondary control 2 4 6 8
