or the system sensor is defective. The cascade
system will still function in this situation and will
function with reduced efficiency. All boilers will
run simultaneously rather than in a staged fash-

CASCADE TT 0123 567
SYS PUMP ON 12:47P
Description: This screen shows information about
the cascade status. The TT in the center of the top
line shows that the cascade demand is coming
from the TT contact being closed. You may also
see DHW if the demand is from a DHW sensor or
0-10 if the demand is from a 0-10 volt input. The
following numbers show which boiler addresses
are currently communicating to the master. If a
boiler address is not used or not communicating,
the number will not show on the display. In the
example above, boiler address #4 is not commu-
nicating. When a boiler in the system is firing, its
address number will alternate with a ‘.’ to signify it
is firing. The bottom line shows the status of the
system pump output contacts.
