- the typical zone controller has three selling features: easy wiring/installation,
troubleshooting LEDs, and priority zone arrangement. Electro
Industries zone controllers also have these features, plus
utility load control interface, but the models EB-ZTS-* and EB-ZS-*
have a major additional feature. The zone controller board
has intelligence which actually communicates to the electric boiler
control board and only stages in the necessary elements for the
capacity required by specific zones (or combination of zones) which
are calling at any instant of time. This means the boiler is sized
correctly to meet the capacity of each connected zone. Example,
there is no such thing as full 27 kW coming on for perhaps a 5 kW
All Electro-Boiler installations considering zone controller should
be matched with Electro Industries zone controller.
Also, the EB-ZTS-1 can be installed within the boiler cabinet, mounting
space is already provided. The EB-ZS-4 can apply to non-Electro
Industries or any Brand X boiler having 3 or 4 sequencers.
