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.
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.

Page 3: Introduction
INTRODUCTION With this WarmFlo configuration, the electric heating elements are automatically staged/modulated and controlled to establish a fixed outlet water temperature. This outlet temperature is sensed by the WarmFlo controller and is controlled to achieve and maintain the boiler’s set point temperature. Even though this WarmFlo configured unit adjusts outlet temperature independent of water flow and prevents high limiting even with marginal water flow, it is still very important that the hydronic system be correctly designed for the building, the total heat loss requirement, and proper hydronics design and... -

a dial switch for each 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. -
Page 6: Multiple Boilers
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. -

Electro Industries, Inc., cannot be held responsible for field modifications, incorrect installations, and conditions which may bypass or compromise the built-in safety features and controls. - Page 8 3. Remember, safety is the installer’s responsibility and the installer must know this product well enough to instruct the end user on its safe use. Safety is a matter of common sense - - a matter of thinking before acting. Professional installers have training and experienced practices for handling electrical, sheet metal, and material handling processes.

7. Zone Valves or Zone Pumps – see Zone Controller section for options. WARNING THE END SWITCHES FROM THE ZONE VALVES MUST BE AN ISOLATED CONTACT WITH NO VOLTAGE PRESENT ON THESE WIRES OR SCREW TERMINALS. THIS IS VERY IMPORTANT TO MAKE SURE THERE ISN’T ANY INTERFERENCE OR FEEDBACK BETWEEN THE TRANSFORMER OPERATING THE ZONE VALVE SYSTEM AND THE TRANSFORMER WITHIN THIS ELECTRO-BOILER PRODUCT. -

11. Close “water supply valve” and disconnect water supply. 12. Optional – energize circulating pump during this fill operation. The water pressure from the household system and as plumbed should typically flow through the circulating pump without the pump running. COMMENT: Purge one loop at a time. -

TROUBLESHOOTING/REPAIR HELPS 1. This WarmFlo controller contains several interference suppression components, but as an electronic logic product, unpredictable and unusual transients or interference may sometimes cause strange results. If the WarmFlo controller is “acting strange”, one immediate step would be power down reset. - Page 19 OPERATIONAL INFORMATION In order for the installer to completely understand the WF II functions and operational sequence it is recommended to thoroughly read and understand the information below.
