APPLICATION:

   

This Electro-Boiler is factory equipped with 

WarmFlo

 smart controller.  

WarmFlo

 automatically regulates outlet water temperature based on a desired 

output temperature set point. 
 
Primary application is any hydronic water heating system where reduced flow or 
radiation can cause overheat conditions (example, zones).  

However

, if it is a 

mixture of large and small zones, the sudden capacity and flow changes may 
cause some internal timing/over temp conditions.  With the mixture of zones the 
Electro Industries’ zone controller option is highly 

recommended.

  

 
This series is equipped for load management interrupt and can apply to standard 
baseboard radiation (not recommended for EB-MS Model), dual heat 
combinations, under floor radiant, wood boiler supplement, etc. 
 

Note: 

If this installation does not include dual heat standby boiler, the front panel 

switch must always be in the “normal” position. 

 

ACCESSORIES:

 

Attached BL001 lists various accessory or option items which are not part of 
basic Electro-Boiler.  See Room Thermostat Placement section for additional 
information on slab stat. 

 
 
 

 

Note: 

This product meets the requirements of the ASME Boiler and Pressure Vessel Code.
