zone and the installer selects one of four zone capacity sizes.  When dialing in the size closest to the zone 
Btu/h capacity, the zone controller “smarts” only allows the appropriate boiler stage which can handle that 
capacity.  Also this is additive if more than one zone calls at any one time – order EB-ZTS-1. 

3.

 

Two temperature system with unbalanced zones

 – if the application includes zone one requiring high 

temperature (fin tube, air handler, etc.) and the remaining zones are radiant floor low temperature, this zone 
controller (EB-ZTS-1) will automatically raise the output of the high temperature zone.  This is a priority 
arrangement, zone 1 holds off the other zones while the high temperature output is heating.  If at the end of 
the high temperature zone there is a call on any of the low temperature zones (up to three plus slave 4), 
there will be a pump only function until the outlet temperature drops below the front panel dial setting. 

 

Field zone controller installation

 – the above mentioned zone controller board is installed within the 

basic cabinet.  

However

, the zone controller board must communicate with the main TS boiler board.  All 

production units after approximately January 10, 2004 have a compatible control board.  If the zone 
controller installation is in a boiler manufactured prior to that date, call factory to review the requirements 
for a main controller board upgrade. 

 

ZONE CIRCULATORS 

 

The EE-5051 switching relay can be used to interface line voltage pumps with the boiler R and W control 
terminals, see drawing BH008.  This switching relay can be combined with the above zone controller 
board. 

 

ROOM THERMOSTAT PLACEMENT 

 

Fin tube radiation, fan coil, etc. – 

heat only wall t-stat, connected to operate zone valves (see previous 

section) or for single zone the t-stat is connected directly to Electro-Boiler R and W. 

 

Floor radiant

 – comfort and proper space heating response is a direct relationship to the thermostat type 

and the placement of the thermostat sensing bulb.  Typically an under floor heating system can be broken 
down into three categories. 

 

A.

 

Energy storage, water tubing is under the concrete or within the sand base

 

– the controlling thermostat must have a remote bulb, and this remote bulb must 
sense the concrete slab temperature (slab stat).  Coordinated with the concrete 
pour, install a ¾” PVC, minimum bend radius of 7 inches, and locate at 
approximately center (vertical) of the concrete slab.  The thermostat sensing 
bulb can later be pushed down this PVC conduit.  If the slab is already poured 
without conduit for slab stat, use electronic remote sensing thermostat such as 
Electro Industries’ 

ES-24-SRO or ES-24-C-RS

.  These devices only require a 

¼” hole drilled in the floor at some convenient location (preferably off a center 
wall, not within 2 feet of outside wall). 

B.

 

Floor covering, medium to high insulation 

– use slab stat as described in paragraph A above. 

C.

 

Quick response, hydronic tubing just under the concrete surface, no flooring material over the 
concrete

 – in this case, heated water can directly radiate into the room, a standard wall mount room 

thermostat is adequate.  Mount room thermostat on an inside wall similar to most heating systems. 

 

MULTIPLE BOILERS 

 

This boiler series now includes a method for automatically staging 
any number of parallel-plumbed boilers.  Order plug-in relay EB-C-
STG5. 
 
The thermostat is connected only to the first boiler, when all stages 
are on for more than 5 minutes, this new plug-in relay module turns 
on the next boiler (R and W), and a second EB-C-STG5 could be 
used to turn on the third, etc.
