DESCRIPTION "CASCINFO" Screen 11
Shows the number of boilers connected with the Cascade. The Master/Lead boiler is designated as 0.
Slave/Lag boilers will be designated 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B. When a “-“is used instead of a number, than
that boiler is either not connected, or in a lockout mode and not available for the Cascade. When an “x“ is
used instead of a number, than that boiler is connected, but in lockout mode.
When a “d” is used instead of a number, than that boiler is handling a DHW demand.
When the number is flashing, then that boiler is providing heat to the cascade. When the leading boiler is
changed according to the set priority change time, than that boiler’s address will be shown first in the row of
numbers.
Example 1: "3 4 5 - - - - - - 0 1 2"
There are six boilers present and nr. 3 has priority.
Example 2: "3 4 x - - - - - - d 1 2"
There are six boilers present and nr. 3 has priority. Boiler 0 is heating up an indirect DHW tank. Boiler 5 is
present, but in a lock-out.
