13.4 - Cascading appliances
Cascading appliances as shown in the diagrams in figures
13-7 (MYDENS) and 13-8 (AGUADENS).
It is necessary to first install the 885 IF board (detail “13” in
figures 3-3, 3-5 and 3-7) in each appliance and acquire the
cascade command 885 HC (see figures 13-7 and 13-8).
A maximum of 8 appliances can be cascaded (examples with
4 are shown in figures 13-7 and 13-8).
Follow the 885 HC command manual for the instructions on
how to cascade appliances.
