Electro Industries has always had a strong desire to internally control all aspects of product control. 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.

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.

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-ZTA-1 - install within boiler cabinet. Configured for zone pumps, zone valves (4-wire, 3-wire, 2-wire, or actuators) TACO self-contained pumps, etc. Eight documented configurations. Priority with dual temperature feature selections. Maximum of 4 zones.
3.
Application: EB-ZEA-1 - with enclosure and 40VA transformer. Same as ZTA for EB-M* and EB-C* Series larger boiler, has enclosure and a second 40VA transformer. Maximum of 4 zones.
4.
Application: EB-ZEA-2 - add additional 4 zones, enclosure and 40VA. Use with EB-ZTA-1 or EB-ZEA-1, extends all features to 8 zones, priority and dual heat still relate to zone 1.
 
** NOTE TO SPECIFIER ** Delete application not required. Pumps.

8.
Application: EB-ZTS-2 - add additional 4 zones, enclosure and 40VA. Use with EB-ZTS-1, extends all features to 8 zones, priority and dual heat still relate to zone 1.
 
** NOTE TO SPECIFIER ** Delete application not required. All Others.
** 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.

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.
 
G.
Diagnostic Tools:
1.
Product: WarmFlo Analyzer, now applicable to all TS Series: Model WF-ANZ7.
 
** NOTE TO SPECIFIER ** Our patented meter base generator transfer switch is the first of its kind. GenConnect is the first transfer switch that doesn't compromise safety in its effort to gain installation simplicity. With the simple meter base installation the GenConnect powers the complete panel - no naming individual circuits. The GenConnect is available in many different styles and amperages that can be suited for your specific needs.
