SL 26-260 G3, SL 40-399 G3 MODULATING GAS BOILERS
2.3 CONTROL INTERFACE
The control interface is provided through a 2-1/4 x 4 inch, color touchscreen display. The
touchscreen 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 touchscreen.
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 border 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 touchscreen, the display shows the Home screen 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 will 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 touchscreen 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.
