2 Introduction Dear Valued Customer: Congratulations on your new purchase! The Steffes ETS heaters are the highest quality storage heat systems available today. We are confident you will be pleased with the warm, comfortable heat this system provides as well as the savings you should see in your electric heat bill. Electric Thermal Storage has been used in the United States for over 20 years. Today, Steffes is known as the leader in this technology.
General Information 3 1 General Operation Steffes ETS room heating units utilize off-peak electricity available during those times of the day or night when the power company can supply you with electricity more economically. By using this offpeak electricity for heating, the power company may offer you a special incentive such as a reduced electric rate, an off-peak heating rate, a time-of-use (TOU) rate, or monthly credits on your heating bill.
4 General Information (cont'd) 2 Terminology This manual contains terms which may need an explanation. The table below lists some of these terms and a brief description of each. TERM DEFINITION Automatic Charge Control Method of brick core charge regulation where a sensor monitors outdoor temperature to automatically adjust the brick core temperature. Brick Core Charge Level The amount of heat that is stored in the heater's brick core.
5 Safety Information 1 Safety Precautions 1. DO NOT energize the heater while disassembled or without ceramic heat storage bricks in place. 2. As is true with all heating appliances, materials that may produce explosive or flammable gases MUST NOT be used or stored near the room heating unit. 3. Be sure the minimum clearance requirements specified in this manual are never violated . WARNING: Violation of the clearance requirements may create a fire hazard! 4.
6 Maintenance and Cleaning As with most heating systems, air borne particles in the room may be drawn into the heating system and oxidized. As these air borne particles are expelled back into the room, they may accumulate on the heater or other surfaces. Over time, these particles may appear as a black residue, commonly referred to as soot.
Describing The Heater's Display Panel ROOM SETTING A green bar will illuminate next to ROOM SETTING on the MODE digit when the room temperature set point is being adjusted. (See Figure 5.) The set point can range from 45oF (7.2oC) through 85oF (29.4oC). SERVICE LIGHT This is one of the many built-in safety devices on the heater. This red light will illuminate whenever the core charging high limit switch has interrupted power to the heating elements.
8 1 Operating the Heater HEATER START-UP On start-up of the heater, you may experience some odors relating to the first time operation of the heating components. There also may be an odor associated with dust accumulation in the system if the heater is shut down for an extended period of time. Allowing the heater to charge to its highest heat storage level (full core charge) will help expel these odors in a timely manner.
Operating the Heater (cont'd) 9 The outdoor sensor will monitor outdoor temperature and provide the information to the heater. The heater will respond by storing heat in the brick core accordingly. The outdoor temperature at which brick core charging in the heater is to begin and the outdoor temperature the heater should be at full brick core charge may be adjusted at the time of installation. The heater comes factory preset to start charging at 60oF (15.
10 1 Installing The Heater PLACEMENT Room heating units can normally be placed on standard flooring systems with any type of covering, i.e. wood floor, carpet, linoleum; but, heater weight must be considered. If in doubt, consult a building contractor or an architect. (Refer to the Heater Specifications section in this manual for weight and physical dimensions of the room heating unit being installed.
Installing The Heater 11 (cont'd) Once the proper circuits are wired to the room heating unit, install a field connection junction box. This junction box must be large enough to conform to all applicable electrical codes and regulations. The junction box can be installed behind the heater or mounted in the floor below the heater. If a location below the floor is chosen, the box must remain accessible for future service to the room heating unit.

28 Advanced Heater Operation (cont'd) Location 1 (L01) - Brick Core Temperature Set Point If Using Automatic Charge Control: The data entered into this location provides a trim adjustment to brick core temperature. As the heater charges automatically in relation to outdoor temperature, this trim will either increase (up by +25%) or decrease (down by -25%) brick core temperature. If you do not desire to use the trim function, this should be set at d05. L01 is factory preset at d05.
Advanced Heater Operation (cont'd) 29 Location 5 (L05) - Automatic Charge Control Full Charge Set Point This location indicates the outdoor temperature where the room heating unit should have a full brick core charge. Example: If Location 4 (L04) has a value of d60 and Location 5 (L05) has a value of d20, the room heating unit will take a proportional charge at any outdoor temperature between these two set points. L05 is factory preset at d20 (20oF which equates to -6.7oC).
30 Advanced Heater Operation (cont'd) Location 9 (L09) - Room Temperature - Minimum Value This location is used to set the minimum room temperature set point. This set point is the lowest temperature to which the room temperature thermostat can be adjusted. For example: If the data value in this location is set to d45, then 45oF will be the lowest room temperature to which the thermostat can be adjusted. When adjusting the room temperature set point below this setting, the heater will be shut off.
Advanced Heater Operation 1. 2. Charge Mode (Off-Peak): See Figure 23 • MODE digit displays a "C". • TEMPERATURE digits display current room temperature. • During this mode, if the temperature of the brick core is insufficient (based on the manual charge setting or the automatic charge control outdoor temperature information), the heating elements will be on. Heat will be stored in the bricks to maintain the appropriate charge level.
32 3. Advanced Heater Operation (cont'd) Anticipated Peak (Pre-Peak) Mode: See Figure 25 This mode is used only in specialiazed installations. You may not have this option enabled on your heating unit. This mode of operation is used in situations where the power company sends a signal to the equipment prior to the possibility of a control (on-peak) period.
