- Digital or standard thermostat
- Applies to other manufacturers electric boilers
- Dual temperature operation
Electro-Boiler/Hydronics - 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-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.
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 2nd 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.
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.
