Electro Industries has always had a strong desire to internally control all aspects of product design and manufacture. We are unique in that we not only internally design our products, but we also fabricate our own sheet metal parts, with a welding department, circuit board assembly, and testing.
As a company, we are continually seeking ways to improve upon and create new products to help our customers better manage their comfort and energy needs. |

| | ** NOTE TO SPECIFIER ** Our radiant electric boilers along with a radiant tubing system, have become one of the most popular heating systems for residential applications. These systems offer the comfort of radiant heat and the cost savings and safety offered by using our electric boilers. Delete if not required. |
| |
| | 2.2 | SMALL ELECTRIC BOILERS |
| | ** NOTE TO SPECIFIER ** When properly designed and installed, cost savings can be seen from 20 percent to 40 percent over conventional forced-air heating. Radiant floor heating will eliminate cold, drafty rooms. It will also get to the hard to reach areas. Radiant systems provide comfort that is unsurpassed. All radiant systems are not the same. Electro Industries understands the design and installation of a quality radiant application. We bring that knowledge to every manufactured product. |
| | Boiler KW as listed is based on 240 VAC single phase incoming power. When operating on 208 VAC single phase incoming power, boiler KW output is reduced by 25 percent. |

| | ** NOTE TO SPECIFIER ** In our 25 plus years of manufacturing boilers, our latest TS Series boiler design offers many benefits that were not previously offered in an electric boiler. The TS Series (EDB-T1-**) allows you the flexibility to accomplish any radiant in-floor need. |
| | Our most deluxe model is designed for multiple temperature and zoning applications. This model has the ability to sense water temperature and maintain an accurate boiler temperature output by only energizing the electric elements for needed output, not full capacity. This model eliminates extra costs associated with relays, extra temperature controls, zone boxes, etc. Our more experienced installers use this boiler to avoid the extra cost of the above.

| | 2.5 | BOILER ACCESSORIES |
| | ** NOTE TO SPECIFIER ** This will simplify your wiring and make zoning applications much easier. In addition, enhanced communicating features have the ability to stage the electric boiler based upon the connected zone capacity. Delete if not required. |
| |
| | | A. | Zone Control: |
| | | | 1. | Construction/Operation: Provide enhanced communicating features provide the ability to stage the electric boiler based upon the connected zone capacity. |
| | | | | a. | Utility load control. |
| | | | | b. | Terminal block wiring, visual wiring layout. |
| | | | | c. | Indicator lights showing zone operation. |
| | | | | d. | 24-volt, 40VA transformer 120/208/240 connection. |
| | | | | e. | Fuse protection. |
| | | | | f. | Priority option. |
| | | | | g. | Dual temperature operation. |
| | | | | h. | Applies to digital or standard thermostats. |
| | | | | i. | Dial switch, select each zone BTU capacity. |
| | ** NOTE TO SPECIFIER ** Delete application not required. Pumps, Actuators, Valves. |
| | | | 2. | Application: EB-ZEA-1 - with enclosure and 40VA transformer. Same as ZTA for EB-Mx and EB-Cx Series larger boiler, has enclosure and a second 40 VA transformer. Maximum of 4 zones. |
| | | | 3. | Application: EB-ZEA-2 - add additional 4 zones, enclosure and 40 VA. Use with EB-ZTA-1 or EB-ZEA-1, extends all features to 8 zones, priority and dual heat still relate to zone 1. |
| | | | 4. | Application: EB-ZES-1. Zone Valves only, has enclosure and a second 40VA transformer. Priority with dual temp feature. Maximum of 4 zones. |
| | | | 5. | Application: EB-ZTS-2 - add additional 4 zones, enclosure and 40 VA. Use with EB-ZTS-1, extends all features to 8 zones, priority and dual heat still relate to zone 1. |
| | ** NOTE TO SPECIFIER ** Delete if not required. |
| |
| | | B. | Two Temperature Zone Controls: |
| | | | 1. | Handled as the priority zone on multi-zone; EB-ZEA-1. |
| | | | 2. | Priority switch on, zone 1 active - TS boiler automatically changes to supply water setting. |
| | | | 3. | All other zones are held off. |
| | | | 4. | With zone 1 satisfied or 60-minute timeout, the boiler automatically returns to the preset temperature and reacts to the other zones. |
| | ** NOTE TO SPECIFIER ** Radiant floor air stat in the same area as a forced air room stat presents serious control problems. A remote sensing slab stat for the radiant floor removes this issue. Remote sensing slab stat is required for storage applications. Delete if not required. |
| |
| | | C. | Slab-Sensing Thermostats: Sensing and controlling the system based upon radiant floor surface temperature. |
| | ** NOTE TO SPECIFIER ** Delete if not required. |
| |
| | | D. | Relays: |
| | ** NOTE TO SPECIFIER ** Delete product not required. |
| | | | 1. | Product: DPDT 24-volt switching relay. 24V coil. 120V, 10A, contact sets: Model EE-5053. |
| | | | 2. | Product: Pump Switching Relay: Model- EE-5051. |
| | | | 3. | Product: Multi-Boiler Relay: Model EB-C-STG5. |

| |
| | | E. | Wiring Adapters: |
| | ** NOTE TO SPECIFIER ** WarmFlo Controller - temperature sensing output and outdoor temperature sensing provide added comfort electric heat modulation and blower speed control for more uniform and comfortable heating. The WarmFlo controller was introduced in 1997 and is a proven and customer accepted technique for providing the maximum comfort and efficiency from your electric unit. |
| | | | 1. | Product: Single Feed Bus for 2 CB's (SQ-D CB) Relay: Model 5701. |
| | ** NOTE TO SPECIFIER ** The WarmFlo Analyzer is a must have tool for all WarmFlo professionals. This diagnostic tool gives you complete control. Whether it's reprogramming chips, troubleshooting, overall system knowledge, or customizing to meet the customer's specific needs, you'll have the answer in the palm of your hand. The Analzyer has saved many contractors from multiple trips to the job site by allowing the service technician/installer the ability to reconfigure any WarmFlo system. |
| | | | 2. | Product: Single Feed Bus for 3 CB's (SQ-D CB) Relay: Model 5702. |
| | ** NOTE TO SPECIFIER ** Electro Industries has had experience working with radiant heat. We have found that in order to achieve a balanced heat using radiant, a slab thermostat is critical. Electric boiler systems require a large mass with very slow response in order to allow electric utility control interruption for off-peak rates. |
