Intr oduction Introduction 2 Dear Valued Customer: Congratulations on your new purchase! The Steffes ETS heaters are of 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.
3 General Infor mation Information What is ETS? 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 off-peak 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.
General Infor mation Information (cont'd) 4 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 heat storage regulation where a sensor monitors outdoor temperature to automatically regulate the brick core charge level. Brick Core Charge Level The amount of heat that is stored in the heater's brick core.
5 Safety Infor mation Information Safety Precautions 1. DO NOT place anything on top of the room heating unit. 2. DO NOT energize the heater while disassembled or without ceramic heat storage bricks in place. 3. 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. 4. Be sure the minimum clearance requirements specified in this manual are never violated .
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.
7 Describing The Heater's Display P anel Panel (cont'd) 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). Figure 5 MODE TEMPERATURE ROOM SETTING STORAGE SETTING This is only applicable when using manual charge control.
Operating the Heater 8 1 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.
9 Operating the Heater (cont'd) Automatic Charge Control If the room heating unit is set for automatic charge control, the brick core charge level will be regulated automatically in relation to outdoor temperature. An outdoor sensor is required for this method of charge control. 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.
10 Operating the Heater (cont'd) Setting the Heater to "OFF" and turning it back "ON" when Using Manual Charge Control Step 1 To turn the heater "OFF", hold the M button until room temperature set point appears on the TEMPERATURE digits of the face plate. Step 2 Use the ò arrow button to decrease the room temperature set point until the control panel face plate displays "OFF". Step 3 To turn the heater back "ON", press and hold the M and the ñ arrow buttons at the same time.
11 3 Installing The Heater (cont'd) ELECTRICAL CONNECTIONS Line voltage connections for direct wired room heating units Heaters that are designed for direct wired connections are equipped with knockouts for installation of the electrical wire. This wiring can be installed with flexible conduit or by installing the electrical cable directly into the heater. If installing electrical cable directly into the heater, be sure this cable is protected and not prone to physical damage.
Installing The Heater 4 12 (cont'd) ATTACHING THE HEATER TO THE WALL NOTE For cross reference to number coded components, refer to the Exploded View Diagram (Figure 15) and the Heater's Parts List. Step 1 Remove screws at the lower edge of the painted front panel (12). Caution should be taken to assure that the screws are removed without scratching the painted surfaces. Step 2 Pull the lower edge of the front panel forward and unhook it from the top panel (1). Carefully set the front panel aside.
13 6 Installing The Heater (cont'd) SETTING THE METHOD OF BRICK CORE CHARGE CONTROL With automatic charge control, outdoor temperature information can be supplied to the room heating unit in one of two ways: Steffes power line carrier system or direct wired outdoor sensor. The room heating unit is shipped from the factory set for automatic charge control for use with the Steffes power line carrier control system. The heater comes preset to start charging at an outdoor temperature of 60oF (15.
Installing The Heater 8 (cont'd) 14 INSTALLER'S INSTRUCTIONS FOR SETTING HEATER OPERATION FUNCTIONS The heater is shipped from the factory preset with standard operating functions. The owner should not have to make adjustments; however, if it is necessary to do so, the Advanced Heater Operation section of this manual explains those functions that are owner accessible and how to change them.
15 Installing The Heater (cont'd) ____ 6. Energize the heater. Set the heater to the charge mode and adjust the room temperature set point above the actual room temperature to initiate a heat call. With a clamp-on amp meter, check for proper amperage draw on the charging circuit. This is done at the L1 terminal block position (#14). Refer to the Unit Identification Label on the lower right side of the heater to determine heater voltage and input wattage of the heater being installed.

Adv anced Heater Operation Advanced Comfort Override (power company permitting) This feature is used to achieve room comfort in the area where the heater is located if the stored heat in the brick core has been depleted. If the power company permits the use of this feature, it will allow the heating elements to come on during a peak mode. This occurs only if the room temperature falls a preset number of degrees below the room temperature set point and the stored heat in the brick core has been depleted.
