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, then that boiler is connected, but in lockout mode.
When a “d” is used instead of a number, then 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, then 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,
