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

EB-5415A - low cost, 2 or 3 zones, sheds one boiler stage (Mini-Boiler enhancement)

ZONE CONTROLLER

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
