Midsize
Model EB-MA-10
This Electro-Boiler is factory equipped with WarmFlo smart controller. WarmFlo
automatically regulates outlet water temperature based upon preset, front panel,
temperature selection.
This model does not have an outdoor sensor and is not
programmed for outlet temperature ramping (outdoor reset concept). If your application
is "outdoor reset", you should be using model EB-MO series. This EB-MA series can
easily be field converted.
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 zone controller ZEA-*
option is highly recommended (see page 2).
This series is equipped for load management interrupt and can apply to standard
baseboard radiation, 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. Also page 3 has additional information on slab stat.

Page 3: Introduction
INTRODUCTION With this WarmFlo configuration, the electric heating elements are automatically modulated and controlled to establish a fixed outlet water temperature. This outlet temperature is sensed by the WarmFlo controller and is controlled by preset, front panel, parameters. 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 installation practices. -

2. Prevents over control or false staging up and down when the temperature sensors are attempting to regulate – since Electro Industries’ zone controller also has staging “smarts”, the addition of the zone controller will provide smoother boiler temperature control. The zone board has a dial switch for each zone and the installer selects one of four zone capacity sizes. -

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-BR. 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). -

MECHANICAL INSTALLATION – CAUTION Electro Industries Inc. requires the use of dielectric isolation between the boiler vessel supply and return piping when the boiler is plumbed using copper or any other dissimilar metal. Damage to the vessel caused by galvanic corrosion voids Electro Industries’ warranty. -

ELECTRICAL HOOKUP Reference drawing BH510 1. 240 Volt Heating Power – route and install the proper current carrying conductors from service panel fuse or circuit breaker. See page 2 Specification Table and/or product nameplate for ratings. These models contain built-in circuit breakers and meet the requirement for local disconnect for appliances greater than 10 kW. -
Page 11: Water Fill Procedure
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. -
Page 13: Operational Tips
OPERATIONAL TIPS Normal/Standby Switch If this system does not have a standby operating (gas or oil) boiler, this switch must always be in the “normal” position. To activate standby boiler, simply position front panel switch to “standby”. Heating Cycle 1. -
Page 14: Standby Switchover, Sot Timer
Cold slab, outdoor reset and temperature sensing prevent full boiler on – by adding a temporary jumper between the lower W screw terminal and the upper left “E” tab, all temperature sensing functions are bypassed and the control board will step in all the stages. Caution: This jumper shall not be a permanent function, jumper needs to be removed after slab is approaching normal temperature. -

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 16 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.
