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

• 24-volt, 40VA transformer

120/208/240 connection

• Fuse protection

• Priority option

• Dual temperature operation

• Applies to digital or

standard thermostats

• Dial switch, select each zone capacity

All Others

EB-ZXA-1 - universal, pumps or valves, non-communicating, for any boiler EB-ZS-4 - automatic staging system for Brand X boilers or dual EB-R, -L, -E Series EB-ZC-4 - wiring and convenience interface, isolated boiler end switch EB-5415A - low cost, 2 or 3 zones, sheds one boiler stage (Mini-Boiler enhancement)

Pumps, Actuators, Valves

EB-ZTA-1 - install within boiler cabinet EB-ZEA-1 - with enclosure and 40VA transformer EB-ZEA-2 - add additional 4, enclosure and 40VA

Pumps

EB-Z2P - two pumps with priority and dual temp.

Zone Valves

EB-ZTS-1 - install within boiler cabinet, encl. option EB-ZTS-2 - add additional 4, enclosure and 40VA

SLAB STAT

Sensing and controlling the system based upon radiant ﬂ oor surface temperature or the concrete mass has very positive beneﬁ ts. Radiant ﬂ oor air stat in the same area as a forced air roomstat presents serious control problems. A remote sensing slab stat for the radiant ﬂ oor removes this issue.

Remote sensing slab stat is required for storage applications.

ES-24-BR

SWITCHING RELAY - EE-5051 MULTI-BOILER - EB-C-STG5

This DPDT 24-volt switching relay provides a convenient solution to any AC or DC application.

OTHER OPTIONS

• Ideal for zone pumps

• 24V coil

• 120V, 10A, contact sets

• Easy to wire and nicely packaged
