ELECTRO-BOILER
3-PHASE MODELS, 208-VOLT
INSTALLATION & OPERATING INSTRUCTIONS
APPLICATION:
This Electro-Boiler is factory equipped with WarmFlo smart controller.
WarmFlo automatically regulates outlet water temperature based upon outside
temperature and pre-setup parameters (commonly called "outdoor reset").
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 ZTS-* 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.
ACCESSORIES:
Attached BL001 lists various accessory or option items which are not part of
basic Electro-Boiler. See Room Thermostat Placement for information on slab
stat. See Zone Controller section for information on a zone control update which
stages elements based upon zone capacity.
Note:
This product meets the requirements of the ASME Boiler and Pressure Vessel Code.

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 outside temperature and by setup parameters. First-time or non-routine user –... -

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. 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 will automatically raise the output of the high temperature zone. - Page 6 Outdoor Reset Option The EB-WX-** boiler comes equipped with an outdoor sensor (shipped loose). This sensor can be connected to the board to allow for outdoor reset function. What is Outdoor Reset? Outdoor reset is where the Electro Boiler DT (desired water temperature) shifts up and down based on the outdoor temperature.

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.
