Screen 11 "CASCINF" Description
The CasInf screen 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, 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 number 3 boiler has priority.
Example 2: "3 4 x - - - - - - d 1 2"
There are six boilers present and number 3 boiler has priority. Boiler 0 is heating up an indirect DHW tank. Boiler 5 is present, but in a lockout.
