Page 3: Introduction
Electric Thermal Storage has been used in the United States for over 20 years. Today, Steffes is known as the leader in this technology. Not only are we setting the industry standards for quality; but, we are also working closely with power companies to ensure comfort, safety, reliability, service, and support needs are being met. -
Page 4: General Information
General Information 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 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. -
Page 5: Terminology
General Information (cont'd) 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. -
Page 6: Safety Information
Safety Information 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. -
Page 7: Maintenance And Cleaning
To minimize the black residue buildup, clean the outer surface of the heater on a regular basis. Wash the cabinet only when cool with any liquid cleaner. Do not use scouring powders or furniture polish. Steffes recommends using "Soft Scrub with Bleach" brand cleanser or its equal. - Page 8 This is only applicable when using manual charge control. A green bar will illuminate next to STORAGE SETTING (on the MODE digit) which indicates the storage level set point can be adjusted. (See Figure 6.) STEFFES Figure 6 MODE TEMPERATURE STORAGE...

Page 9: Operating The Heater
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. -
Page 10: How To Turn The Heater "Off" And "On
Operating the Heater (cont'd) 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. -
Page 11: Installing The Heater
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 contrac- tor or an architect. (Refer to the Heater Specifications section in this manual for weight and physical dimen- sions of the room heating unit being installed.) When installing on extremely thick carpet, it may be necessary to slightly elevate the heater to avoid carpet contact with the air discharge grill. - Page 12 Installation instructions for this method of control are provided with the Steffes power line carrier control system. If using a time clock for peak control of the heater, the time clock is connected to the heater via low voltage wiring.

Page 15: Remote Room Sensor (Optional)
The heater's built-in receiver will pick up the signals being transmitted on the power line and respond accordingly. PLC control is available with the use of the Steffes PLC Transmitter or the Steffes Comfort Control Relay Panel (CCRP). Only one PLC system is needed in an installa- tion. -
Page 16: Installer's Final Checkout Procedure
Set the heater to the charge mode and adjust the room temperature so the blower is operating. With a clamp- on amp meter, check for proper amperage draw on the charging circuit(s). On Models 2002 and 2003, this is done at B1 terminal block position. On Models 2004, 2005, and 2006, this is done by totalling the readings from the B1 and R1 terminal block positions (30). - Page 17 (AMP draw is calculated by taking the total input wattage divided by the input voltage. Allow +/- 5% tolerance at nominal input voltage.) ____ 6. Make certain all fuses and/or circuit breakers are labeled in the distribution panel. Use the Steffes orange panel label provided in the wall mounting bracket hardware package (53). NOTE This label is important since the heater may be connected to more than one branch circuit.

Page 28: Temperature Conversion Chart
Advanced Heater Operation (cont'd) TEMPERATURE CONVERSION CHART The room temperature display can be set to read in Celsius or Fahrenheit. All other heater functions relating to temperature will be reflected in Fahrenheit only. Use this conversion chart to equate the Fahrenheit reading to Celsius, if desired. - Page 29 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.
- Page 30 Advanced Heater Operation (cont'd) 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.
