3.2 Introduction
Once the boilers are installed and configured
there are still a number of functions available
for the overall system Settings, the Status of
the Boilers, Heating Circuits, and Cascade.
The status screens of each boiler in the
cascade are the same, they show the same
information in relation to the boiler, and each
slave will show the following screen:
<
Boiler Name & Model No.
>
Operation: Standby
Boiler Setp.: 0%
Boiler cap.: 0%
Flow temp.: 40.2ºC
The Master will show the same except for
a small left pointing chevron in the top left
hand corner, this is indicating that there is a
second status screen access by turning the
knob anticlockwise:
<
Boiler Name & Model No.
>
Operation: Standby
Boiler Setp.: 0%
Boiler cap.: 0%
Flow temp.: 40.2ºC
On the Master boiler in the cascade there
is an additional status screen which gives
information in relation to the system, on
rotating the knob anticlockwise:
<
Boiler Name & Model No.
>
Operation: Standby
Plant Setp.: 0%
Plant cap.: 0%
Header: 40.2ºC
The chevron will now be right pointing
and appear on the top right hand corner,
indicating that there is another status screen
accessed by rotating the knob clockwise. In
this case back to the Boiler status screen.
If any boiler faults exist, there will be another
right pointing chevron on the boiler status
screen. For boiler specific faults refer to the
Boiler User guide.

the knob rotated the display backlight will
