ELECTRO-BOILER TS Series INSTALLATION & OPERATING INSTRUCTIONS Model APPLICATION: EB-WO-13 EB-WO-18 EB-WO-23 EB-WO-27 This Electro-Boiler is factory equipped with WarmFlo smart controller. WarmFlo automatically regulates outlet water temperature based upon outside temperature and presetup parameters (commonly called “outdoor reset”). Primary application is any hydronic water heating system where reduced flow or radiation can cause overheat conditions (example, zones).

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 – before attempting installation or setup of a WarmFlo product, we suggest studying the last section of this manual, Operation Information and Technology Definitions.
APPROVED TUBING/PIPING When plumbing this boiler and its peripheral parts to the loop system, all plumbing parts and/or tubing must be sealed to prevent entrance of oxygen. Use only tubing or polyethylene tubing with oxygen Diffusion Barrier. SYSTEM OR WATER FLOW In order to prevent hi-limiting and assure full 20+ years parts life, the piping system/basic plumbing/circulator pump must be arranged to provide flow greater than minimum GPM shown in Table 1.
Also there are LED’s associated with the thermostat action and the zone valve action. This greatly simplifies wiring and future troubleshooting with a neat terminal block wiring arrangement and the onboard LED’s – order EB-ZT*-1. 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.
TWO-TEMPERATURE OPERATION OR FEATURE When using Electro’s zone controller in priority mode, the boiler system can automatically raise the outlet temperature with zone 1 calling. This is setup for default of 150° or pulling a jumper peg the high temperature value is 176°. See appropriate zone controller installation manual for details. BOILER/PLUMBING KIT PLACEMENT This model series is wall hung and the vessel must be vertical, drawing BX501.
or backup gas/oil boiler, etc. Any instructions or comments made within this manual (or factory phone assistance) relating to the gas/oil furnace are provided as comments of assistance and “helps” only. CAUTION Hazards or unsafe practices could result in property damage, product damage, severe personal injury and/or death. 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.
MECHANICAL INSTALLATION – UNDER-FLOOR RADIATION 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. Reference drawing BX501 1. With the typical radiant floor system, a dual heat backup boiler is uncommon.
MECHANICAL INSTALLATION – DUAL HEAT 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. Reference drawing BX201 1. Unpack the Electro-Boiler. The safety relief and pipe fittings are packed within a small carton. 2.
ELECTRICAL HOOKUP Reference drawing BH502 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. Connection is at the circuit breaker terminals.
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. Once this has been determined, all end switches are simply paralleled with the two wires going to “R” and “W”. 8.
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. CONTROLLER SETUP The front panel contains a red temperature select “knob” with two selection ranges – high mass/low mass.
Circulator pump mode – as factory set, the circulator pump is controlled directly from the “W” input terminal. In this setup the circulator pump continues during load control interrupt (or optional remote standby switch). There is a provision within the controller board (inside) to allow the circulator pump to not operate during load control interrupt. On the inside control board, just above the two bottom terminal blocks, is a small pin jumper arrangement. The black “device” sets up the pump mode.
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”. Monitor Lights, Front Panel HI-LIMIT, red – this will only illuminate when the vessel hi-limit opens due to excessive high water temperature. This hi-limit is self resetting. PWR ON, green – basically this is illuminated at all times.

7. Use general heating system logic information and basic understanding of the terminal block wiring functions measure various voltage points to determine proper operation. 8. Acquiring the PC software or Palm with serial port hookup cable is a positive tool for understanding and troubleshooting the WarmFlo controller. Either test set device can display all temperatures, real time evaluation of WarmFlo functions and provide temperature offsets for assimilating winter conditions.
The time between stage turn on depends upon where the controller logic memory was after the last thermostat call or following a power up reset condition. The longest time between staging is from the power up condition because the logic does not have a history of previous thermostat calls. Once the history of several thermostat calls has been established within memory, it automatically returns to the last active stages, with an approximate 5 seconds between stage turn on.
BOILER ACCESSORIES ZONE CONTROLLER This will simplify your wiring and make zoning applications much easier. In addition, enhanced communicating features have the ability to stage the electric boiler based upon the connected zone capacity.
