USER’S INFORMATION MANUAL
SL SERIES BOILERS
Control Interface
The control interface is provided through a 2-1/4 x 4 inch, color Touch Screen
display. The Touch Screen responds to a light finger touch on the screen. You
can also use a stylus or similar device to operate the touch controls. Do not use
a sharp or metallic object such as a screw driver to operate the control as it could
damage the touch screen.
The controller display is divided into two areas, the screen active area and the
boiler status bar. All screens have an active area consisting of the screen title bar
at the top and a boarder surrounding the active area. At the bottom of the display
there is space reserved for the boiler status bar.
Prior to any interaction with the touch screen the display will be showing the
Home screen that includes details of the current boiler status. If the controller
has been left on the Home screen long enough (user adjustable, 10 minutes by
default) the display with be dimmed to save power.
The control will automatically return to the home screen if left unattended.
The screens will step back one screen at a time in 10 minute increments if the
touch screen has not been touched. The pop-up windows will also step back
automatically in 2 minute intervals.
The boiler status bar indicates if the boiler is in a normal, warning or alarm
state. When no warning or alarm state is present, the bar will be green and the
time will be displayed inside the green area. The bar can also be yellow or red
corresponding a warning or alarm state. Text inside the bar will indicate the
specific warning or alarm present. If more than one alarm is present the text
display will slowly change, rotating though whatever alarms that are present.
