Electro Industries EB-ZTA-1 Quad Zone Multi-Use Electric Boilers Controller
EB-ZTA-1 Multi Use Quad Zone Controller will simplify your wiring and make zoning applications much easier. In addition, enhance features and has the ability to stage the electric boiler upon the connected zone capacity.
The typical zone controller has three selling features:
- Easy wiring/installation.
- Troubleshooting LED.
- 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.

The majority of the Electric Boilers including Mini-Size Boilers, Midi-Size Boilers, TS Series and Commercial Boilers with hydronics heating, installations have several zones or thermostats in various rooms. When one thermostat calls for heat it represents only a partial load to the boiler. In most dual heat installations this Electric Boilers are plumbed in series with an existing oil, gas, or wood boiler. For gas or oil, the Electric Boilers is generally at the gas/oil outlet; but for wood, the Electric Boilers including must be on the inlet sides. The standby boiler cannot be operated as hot boiler. This will defeat the Electro-Boiler. Rewire as required using EB-S-SB, standby boiler is turned on from the brown wires. In the case of existing fossil fuel boiler conversions, it is assumed the expansion tank, valving, air bleeder, and circulation pump are in place, in good operating condition, and adequate for the overall system design. In the case of new installation (floor radiant or baseboard), use standard hydronics water heating practices for the necessary expansion tank, air bleeder, valving, water pump, etc., sized for the total capacity of the system. The Electro-Boiler is turned on with an R and W closure from the zone system wiring.
