8 ZONE CONTROLLER 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. Standard Features Terminal block wiring, visual wiring layout Indicator lights showing zone operation 4-volt, 40VA transformer 0/08/40 connection Fuse protection Priority option Dual temperature operation Applies to digital or standard thermostats Dial switch, select each zone capacity Pumps, Actuators, Valves EB-ZTA- - install within boiler cabinet EB-ZEA- - with enclosure and 40VA transformer EB-ZEA- - add additional 4, enclosure and 40VA Pumps EB-ZEA8 - with enclosure and 40VA transformer for 8 zone pumps Zone Valves EB-ZTS- - install within boiler cabinet, encl. option EB-ZTS- - add additional 4, enclosure and 40VA EB-ZES8 - with enclosure, no transformer, for 8 zone valves SLAB STAT Sensing and controlling the system based upon radiant floor surface temperature or the concrete mass has very positive benefits. Radiant floor air stat in the same area as a forced air roomstat 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. ES-4-BR SWITCHING RELAY - EE-505 This DPDT 4-volt switching relay provides a convenient solution to any AC or DC application. Ideal for zone pumps 4V coil 0V, 0A, contact sets Easy to wire and nicely packaged CIRCULATING PUMPS Electro stock includes three pumps sizes and three flange kit (with valve) sizes. MULTI-BOILER - EB-C-STG5 Electrically connects between nd and rd, rd and 4 th, etc. OTHER OPTIONS SOT- Switchover to standby, total run time 570 Single feed bus for CB s (SQ-D CB) 570 Single feed bus for CB s (SQ-D CB) EB-S-SB Dual boiler option for EB-S Series WF-ANZ7 WarmFlo Analyzer, now applicable to WO and WA Series INSTALLATION PLUMBING KITS For convenience of installation, Electro has plumbing kits tailored for each boiler series.
