Select the setpoint you want to change, then
enter the new value
3. If you press the Details button, the control
software leads you to a “ring” of screens that
include some information about the way the
Lead/Lag system is set up. The screens in
this section are “read only” – you can read
the values, but you cannot change them using
these screens.
8.5 While Operating - Checking
Individual Parameters
As we said, the Lead/Lag functions control the
operation of the whole system. You might also
want to check the functions on one of the individual
controllers, and the system gives you a way to do
this.
1. From the ‘home’ screen (Fig. 33), press the
icon for the individual controller you want to
check. In this example, we will press the icon
on the left.

2. The Status Summary page for that controller
will appear. This shows the current operating
condition of that controller, and also shows
some of the configuration settings. See Fig. 34.

Status Summary screen:
• Configure – Allows an installer to change
some of the setup parameters used by the
system. A password may be required.
• Operation – Used to adjust the setpoints,
change the fan speed, turn a burner on or
off, or turn the pumps on or off.

tests, or check the inputs and outputs used
by the system.

all of the setup parameters on the control
system.
3. You can also press the button for Modulation
