Why our zone controller?

• Electro Industries' enhanced design communicates zone capacity information to the boiler
• Electro Industries' zone controllers control boiler staging

Zone Systems

Electro-Boiler/Hydronics - the typical zone controller has three selling features: easy wiring/installation, troubleshooting LED’s, and priority zone arrangement. Electro Industries’ zone controllers also have these features, plus utility load control interface, but the models EB-ZT* 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 zone requirement.

All Electro-Boiler installations considering zone controller should be matched with Electro Industries’ zone controller.

Also, the EB-ZTS-1 or EB-ZTA-1 can be installed within the TS Series cabinet, mounting space is already provided.

Specify EB-ZTS-1 (EB-ZTS-2 adds 2^nd 4 zones)

Brand X Boiler Upgrades - a universal model can apply to any boiler which has 3 or 4 stage sequencers (can be relays). The wiring and staging functions are identical to the unit above. This model has the setup zone capacity dial switches and interprets each zone capacity to control the stages within Brand X boiler.

Specify EB-ZS-4

Older Electro-Boiler upgrades - models EB-ZR-4 or EB-ZS-4 can apply. Also EB-ZS-4 can be used for dual EB-R Series boilers.

Convenience/wiring interface - zone controllers equivalent to other units on the market are also available. These provide the simplified installation, troubleshooting LEDs, wiring terminal blocks, etc. basically the same as others available. This series does not have stage setting or zone capacity dial-in, but does have the added utility load control interrupt features.

Specify EB-ZC-4
