Model: EDB-T1 Series
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 radiant floor heat, baseboard heat, staple up, fan coil and
other hydronic heat applications such as domestic hot water using an indirect heat
exchange water heater tank. This series can also be used in conjunction with a
gas boiler for dual fuel heating.
Note: If this installation does not include dual heat standby boiler, the front panel
switch must always be in the "normal" position.
Various accessory or option items which are not part of basic Electro-Boiler
available, contact factory.

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 better solution would be to use an Electro Industries zone control panel compatible with this series boiler Electro Industries’ Zone Controllers – the Electro Industries’ zone controller has many unique features that enhance the performance and operating efficiency of the EDB-T1 boiler. -

ZONE CONTROLLER features for use with EDB-T1 Boiler 1. Zone wiring and troubleshooting convenience – the addition of the zone board allows for easy terminal block and point to point wiring for each zone thermostat and each zone valve. Also there are LED’s associated with the thermostat action and the zone valve action. -
Page 6: Boiler Placement
What is Outdoor Reset? Outdoor reset is where the Electro Boiler DT (desired water temperature) shifts up and down based on the outdoor temperature. The water temperature coming out of the boiler will be higher when it’s cold outside and lower when it’s warmer outside. The idea is to have the boiler work with the building heat loss to maintain a more even BTU delivery to the space. -

MECHANICAL INSTALLATION – UNDER-FLOOR RADIATION CAUTION Electro Industries 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. - Page 9 MECHANICAL INSTALLATION – DUAL HEAT CAUTION Electro Industries 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.

Page 13: Staging/Modulating Jumper
Staging/Modulating Jumper The control board on the EDB-T1 boiler is a universal controller with the capability of interfacing with many different models of TS Electro-Boilers. If you are working with an EDB-T1 this should be set to MODULATE. Circulator pump mode – as factory set, the circulator pump is controlled directly from the W input terminal. -

Manual Reset Hi-Limit At the top of the vessel there will be either two or three surface mount hi-limits preset at 205° F. There is no light indicator associated with these safety hi-limits. These 205° F safety limits break the L2 current carrying 240/208-volt wire going to the elements, use caution when troubleshooting or resetting. -

TROUBLESHOOTING/REPAIR HELPS 1. This WarmFlo controller contains several interference suppression components, but as an electronic control, 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. Simply turn off boiler power or breaker number 1, when the green LED goes out, count to 1Ø, and re- energize power supply. -
