Edge [ii] Controller Operation Manual
SECTION 7 – UNIT STATUS

7.2 Unit Status

The Unit Status screen is the default Operating screen. It also appears when the unit powers
on (post the splash screen), comes out of sleep mode or has a successful flame. The system
automatically transitions to the Ignition screen during the Ignition sequence.
In normal operation, the area just below the screen heading displays operating status. However,
if there's an operating error, it displays the error condition in red, as shown above.
The following notes apply to this screen:
For boilers with a single inlet port, the Unit Status screen will not display the upper Inlet
data and associated tag.
The Flame Strength is displayed in %, up to 100%.
The Setpoint is not displayed if the unit is part of a "Client" in a BST cascade.
The Max. Fire Rate parameter is displayed when the max fire rate is set to a value
other than 100% and the unit Target Fire Rate is -1% or more from the Max Fire Rate.
