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.
When off-peak hours are available, the room heating unit converts electricity to heat which is then stored in its ceramic brick core. The ceramic brick core of the heater can store heat at varying levels depending upon outdoor temperature, owner preference, utility peak conditions, and the requirements of the space being heated. This stored heat becomes available for space heating needs as determined by the room temperature sensor located in the heater. (An optional remote room temperature sensor is also available. Order item #1302024.)
Heating is accomplished radiantly and by a thermostatically controlled blower. A small amount of heat will be radiated by the heater's cabinet. However, most of the heating requirements in the area where the heater is installed will be satisfied by the heater's blower. When the room thermostat senses a need for heat, the heater's blower will circulate room air through the heater's ceramic brick core. This air is heated and discharged back into the room to maintain a constant, comfortable room temperature.

DEVICE NAME FUNCTION
Core Charging High These limit switches run across the entire back of the heater and Limit Switches monitor the temperature of the outside back panel and the
heater's brick core. If the normal operating temperature is exceeded, this switch will interrupt power to the heating elements and prevent heat from being stored in the brick core. The red "SERVICE" light will illuminate to indicate this switch has shut the power off to the heating elements. (This switch will auto­matically reset when the temperature returns to a normal range.)
Red "SERVICE" Light Illuminates when the core charging high limit switch has
interrupted power to the heating elements. The heater will not store heat in the brick core when this light is illuminated. Illumination of the light may indicate there is not enough clearance between the heater and some object; or, possibly, there is an operational difficulty within the heater. If the clearance requirements have been maintained and the light illuminates repeatedly, notify a service technician. (Since this light works in conjunction with the core charging high limit switch, it will automatically turn off when this switch resets.)

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. High concentrations of air borne particles from such things as aerosols, dust, candles, incense, pet hair, high humidity, smoke, or cooking can contrib­ute to poor indoor air quality and accelerate this process.
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.
Regularly vacuum around all sides of the heater. Check the back of the heater to make sure no objects have fallen behind it. Check all sides of the heater to be sure the required clearances are not being violated. Objects should never be placed on top of the heater. No additional routine maintenance is required.
Maintenance and Cleaning
Describing The Heater's Display Panel
All operational functions of the heater are stored in the heater's microprocessor. These operational functions are factory preset; however, they can be adjusted by the user or installer. All operational functions are accessed through the heater's control panel. Typically, the user will only need to use this panel to adjust the room tempera­ture; and, possibly, to set the brick core temperature if manual charge control is used.
TEMPERATURE and MODE Digits
Typically, these digits continuously display current room temperature and one of the following brick core operating modes (Refer to the Advanced Heater Operation section of this manual for more information):
C = (charge period) Off-peak time in which the heater is allowed
to store heat in its brick core. (See Figure 2)
P = (peak period) On-peak time in which the heater is not
allowed to store heat in its brick core. (See Figure 3)
A = (anticipated peak period) Used only in certain utility pro-
grams. It is an alternative method of storing heat in the heater's brick core. (See Figure 4)

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. This interruption may be the result of not enough clearance between the heater and some object; or, possibly, there is an operational difficulty within the heater. If this light is illuminated, the heater will not store heat in the brick core. It will automatically reset (turn off) when the core charging high limit switch restores power to the elements. (Refer to Table 1, Built-in Heater Safety Devices, for more information on the light and the core charging high limit switch.)
If the light illuminates REPEATEDLY, notify a service
technician.
STORAGE SETTING
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.)

HEATER START-UP
1
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.
Since room air passes directly through the hot brick core of the heater, air borne particles and odors may be drawn into the heating system and oxidized. During the oxidation process, odors can be amplified; thus, it is recommended not to operate the heating system if odors such as that from paints, varnishes, or chemicals are present in the air. Allow the area to be completely aired out before operating the heater.
ADJUSTING THE ROOM TEMPERATURE SET POINT
2
Room temperature set point is adjusted differently if using manual charge control versus automatic charge control. Thus, when making adjustments to the room temperature set point or the brick core charge level, you must determine whether your heating system is set for automatic or manual charge control.
Automatic charge control - The right indicator light on the control panel will be illuminated. With automatic
Operating the Heater
charge control, a sensor regulates the amount of heat stored in the heater's brick core automatically in relation to outdoor temperature.
Manual charge control - The right indicator light will not be illuminated. With manual charge control, the
user regulates the amount of heat stored in the heater's brick core in relation to outdoor temperature.
How to Adjust Room Temperature Set Point if Using Automatic Charge Control Step 1 Press the arrow button to increase the set point or the arrow button to decrease the set point.
The face plate will automatically return to displaying current room temperature a few seconds after making an adjustment.
How to Adjust Room Temperature Set Point if Using Manual Charge Control Step 1 Press and hold the M button until a green bar appears on the MODE digit of the control panel face
plate to indicate room setting can be adjusted. The room temperature set point will appear on the TEMPERATURE digits of the face plate.
Step 2 Press the arrow button or the arrow button to adjust the room temperature set point. The face
plate will automatically return to displaying current room temperature after making an adjustment.
ADJUSTING THE BRICK CORE CHARGE LEVEL
3
The room heating unit's brick core charge level can be regulated either manually or automatically. The method of control will be set at the time of installation. If the right indicator light is illuminated on the face plate, the heater is set for automatic charge control. If it is not illuminated, the heater is set for manual charge control. The room heating unit will come factory preset for automatic charge control.
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.
Page 10
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. The heater comes factory preset to start charging at 60oF (15.6oC) and to be at full brick core charge at 20oF (-6.67oC).
Manual Charge Control
If manual charge control is being used, the owner must periodically adjust the brick core charge level setting during the heating season in relation to outdoor temperature and the heating requirements of the area. To adjust the brick core charge level, do the following:
Step 1 Press and hold the M button until a green bar appears on the MODE digit of the control panel face
plate next to room setting. Release the button.
Step 2 Press the M button again. The green bar on the MODE digit of the control panel face plate will
move to indicate storage setting can be adjusted. Core charge level set point is displayed on the TEMPERATURE digits.
Step 3 Press the or arrow buttons to adjust the core charge level set point. The core charge level can
be set to any data value from 00 through 10.
9
00 = no core charging will occur 05 = 50% core charge will be maintained 10 = maximum core charge will be maintained
The face plate will automatically return to displaying current room temperature a few seconds after making an adjustement.
HOW TO TURN THE HEATER "OFF" AND "ON"
4
You may wish to turn the heater off during the summer months. Brick core charging and room temperature sensing can be turned off without disconnecting power to the heater.
Using Automatic Charge Control
Step 1 To turn the heater "OFF", use the arrow button to decrease the room temperature set point until
the control panel face plate displays "OFF".
Step 2 To turn the heater back "ON", press the arrow button to adjust room temperature to the desired set
point.
Using Manual Charge Control
Step 1 To turn the heater "OFF", hold the M button until room temperature set point appears on the TEM-
PERATURE digits of the face plate.
Step 2 Use the  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 arrow buttons at the same time.
When room temperature set point displays on the face plate, let go of the M button. Use the arrow button to adjust room temperature to the desired set point.

CAUTION
NOTE
PLACEMENT
1
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.)
When installing on extremely thick carpet, it may be necessary to slightly elevate the heater to avoid carpet contact with the air discharge grill. The carpet should not come within ¾ inch of the air discharge grill openings.
Heaters can be placed on an outside or inside wall. Best operating efficiency will be achieved by placing it along an inside wall, adjacent to an outside wall. Avoid installing the heater near sources of extreme heat or cold so the built-in room temperature sensor can sample proper room air temperature. It is also best to not place the heater near an open stairwell.
CLEARANCE REQUIREMENTS
2
Allow a minimum of 1½ inches of clearance from the sides and back of the heater and a minimum of 3 inches from the top of the heater. The factory supplied wall mounting bracket, located on the heating unit's shipping pallet, will provide the correct wall-to-back-of-heater clearance. If the heater is a 120V plug-in model with a security base, the base will provide the proper wall-to-back-of-heater clearance. The base is packaged inside the shipping box on the back side of the heater.
Installing The Heater
If enclosing the room heating unit in a wooden cabinet or recessing the room heating unit into a wall, allow 2 inches clearance on sides and 4 inches on top. Do not enclose or otherwise obstruct access to the heater's front panel and grill. Objects such as curtains, furniture, or bed covers must be kept a minimum of 4 inches from all room heating unit surfaces and 15 inches from the grill.
If there is less than a 12 inch clearance on the right side of the room heating unit, we recom­mend installing a remote wall mounted room temperature sensor. (Order item #1302024.)
ELECTRICAL CONNECTIONS
3
Line voltage connections for direct wired room heating units
Heaters that are designed for direct wired connections are equipped with flexible conduit installed in the room heating unit’s back panel. This conduit is pre-wired for ease of field connections. The wiring in the conduit may not be the same size as the field wiring conductors.
Direct wired heaters are capable of being connected to more than one branch circuit. One or two charging circuits may be utilized depending on room heating unit size (See Table 2). Each room heating unit is capable of being connected with a separate blower and element circuit or with one circuit for blower and element operation. To determine the correct wire sizes for the room heating unit being installed, refer to the Unit Identification Label on the lower left side panel. (See Figure 11. Table 1 and Table 2 will also provide information on conductor sizing.)
Never install Class II (low voltage) wiring or any wiring in a line voltage area unless the wire is rated for line voltage.
Page 12
Installing The Heater (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. If a location behind the heater is chosen, the box should remain as near the floor as practical.
A panel label is provided in the hardware package to identify the branch circuits feeding the room heating unit.
11
IMPORTANT: This label must be applied in the electrical panel and circuits must be identified.
Line voltage connections for cord connected, plug-in room heating units
120V cord connected room heating units must only be used with receptacles that are of the grounding type and suitable for the load of the heater. See the Unit Identification Label on the lower left side panel of the heater to determine correct circuit size. (See Figure 7 for cord and receptacle requirements.)
The room heater's cord has a plug as shown in Figure 7A. An adapter, as shown in Figure 7B, is available for connecting three-blade grounding type plugs to two-slot receptacles. The green grounding means extending from the adapator must be connected to a permanent ground, such as a proprerly grounded outlet box as shown in Figure 7C. This adaptor should not be used if a three-slot grounded receptacle is available.
Heating element (brick core charging) control wiring connections for all room heating units
The heating elements in the heater are capable of being controlled on-peak (not able to store heat in the brick core) via low voltage wiring, line voltage wiring, with a wireless power line carrier signal, or with a time clock. The power line carrier transmitter and time clock are optional control devices. If either of these methods of control are desired, they must be specified at the time of order to be included with the heater shipment.
grounding
FIGURE 7
adapter

If using low voltage control, all connections to the room heating unit’s control circuit must be routed through the low voltage raceway using the factory installed wiring. Class II (low voltage) wiring should never enter a line voltage area of the heater, including its umbilical cord, unless it is rated for line voltage. (See Figures 13 and 14.)
If a power line carrier transmitter is being used for peak control of the room heating unit, low voltage connections are not necessary. The transmitter can be mounted indoor or outdoor. It will transmit the peak control signal through the entire power line system in the building. In addition to providing peak control information, it will also transmit outdoor temperature information for automatic brick core charging. 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. An installation instruction sheet is included with the time clock. Please refer to these instructions for installation of this device inside the heater.
If line voltage control is utilized, an external switching device (such as a relay panel) is necessary to directly control the heating element charging circuit. If relying on this method of control, the face plate on the heater will continuously display a brick core operating mode of “C” (charge) regardless of whether it is an off-peak or on- peak time. It is suggested that the installer change the heater so that current room temperature followed by an
“F” (Fahrenheit) or “C” (Celsius) is displayed. This is done by adjusting the data in Location 14 (L14) to d01,
or a peak control sequencer can be installed to correct the brick core operating mode display. (Order item #1309006.)

ATTACHING THE WALL MOUNT BRACKET OR SECURITY BASE
Installing The Heater (cont'd)
For cross reference to number coded components, Refer to the Exploded View Diagram (Figure 18) and the Heater Parts List.
The room heating unit is attached in one of two ways: wall support bracket (54) or security base (51 and 52). Follow steps 1 and 2 regardless of the method of attachment.
Step 1 Remove the screws at the lower edge of the painted front panel (18). A plastic grill guard is provided
to protect the grill from being scratched while removing the screws.
Step 2 Pull the lower edge of the front panel forward and unhook it from the top panel (19). Carefully set
the front panel aside.
If installing a unit with a wall bracket, do step 3. If the room heating unit being installed is equipped with a security base, proceed to step 4.

The wall bracket MUST be mounted with the label facing up and the lag bolts must attach to wood wall studs. If the wall is not a standard wood studded structure, alternate fasteners must be used to securely attach the wall bracket.
Step 4 (Do this step only if installing a heater with a security base.) 120V plug-in cord models may come
equipped with a security base (51 and 52) rather than a wall support bracket (54). This base must be attached to the bottom panel of the room heating unit. It is packaged inside the shipping box on the back side of the heater. The hardware needed to mount the base to the heater is in a package located in the lower right side of the heater (near the blower).
To install the base, gently lay the room heating unit on its back. You may find it helpful to elevate the bottom of the room heating unit a few inches to make the installation of the base easier.
Align the holes in the security base with the pre-drilled holes in the bottom of the room heating unit. Using the six #14 x 1¼ inch sheet metal screws provided in the hardware package, attach the security base to the painted bottom panel (9) of the room heating unit.
After the base is attached, return the unit to its upright position and place into room location in preparation for brick loading.

BRICK LOADING
5
For cross reference to number coded components, refer to the Exploded View Diagram (Figure
18) and the Heater Parts List. Refer to the Heater Specifications section in this manual for the number of bricks required for each heater model.
Step 1 The heater must be securely mounted to the wall or to its security base (if equipped) prior to brick
loading.
Step 2 To catch brick debris, to protect the flooring, and for easy clean-up upon
completion of the installation, place the room unit's shipping box in front of the room heater before loading the brick.
FIGURE 9
Note: Row 8 brick faces down

Step 3 Remove the screws on the right side of the galvanized front panel (14).
Rotate this panel to the left and remove.
Step 4 If installing a Model 2004, 2005, or 2006, remove and discard the
cardboard spacer(s) that secured the heating elements (12) during shipment.
Step 5 Begin the brick loading with row one by installing the first brick (13)
face-up in the far left side (as you face the heater) of the room heater's storage cavity. (See Figure 9 for a side view of brick stacking.) Be sure the grooved side of the brick is up, and that it fits tight against the right aluminized steel air channel (47).
Install bricks carefully to avoid damage to the bottom insulation panel (49) and to the back insulation panel (23) inside the brick cavity.
Step 6 Continue the brick loading process installing the remaining brick in row
one from right to left. Load remaining rows, one row at a time, begin­ning with left brick, then loading from the right to left. All bricks in rows one through seven must be loaded with the grooved side up.
Avoid loading bricks in a fashion that would cause an uneven horizontal line across the brick core. Bricks should line up side-to-side.

Step 7 Install the eighth (top) row of bricks with the grooved side of the bricks facing down. (See Figure 9.)
A 3" x 11" metal brick installation tool is enclosed in the Owner's Manual packet to assist with loading the top row of brick. Be careful if using this tool as the edges are sharp. To use, be sure to bend one end down to avoid contact with the sharp edge. Lay the metal tool over the far right brick in row 7 with the bent end out. Slide a brick over the metal piece and into position. Pull the metal piece out. Continue this procedure until the entire top row of bricks are installed.
IMPORTANT: The top bricks (row 8) must face downward.
Step 8 Once all bricks are loaded, replace the galvanized front panel (14).
SETTING THE METHOD OF BRICK CORE CHARGE CONTROL
6
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 (15.6oC) and to be at a full core charge level at 20oF (-6.7oC). (The installing electrical contractor or power company personnel will have more information on how to adjust these temperatures to more accurately reflect the climate in your area, if necessary.)

Power Line Carrier and Automatic Charge Control
The Steffes power line carrier (PLC) control system has the capability of sending outdoor temperature informa­tion, WIRELESS, to an unlimited number of 2000 series heater for automatic charge control. No direct wiring to the heater is required with a PLC control system. The outdoor temperature information is transmitted through the entire power line system in the home or building. 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 installa­tion. If using the PLC Transmitter and installing it outdoors, an outdoor sensor may be utilized but is not re­quired. If installing the PLC Transmitter indoors or if using the CCRP's built-in PLC system, one external outdoor temperature sensor is required for automatic charge control. An installation procedure manual will accompany the PLC Transmitter and CCRP. Please refer to these instructions for installation of either device.
Direct Wired Outdoor Sensor and Automatic Charge Control
An outdoor sensor can be direct wired into each room heating unit using low voltage wire. One outdoor sensor is required for each room heating unit that is installed. An installation instruction sheet is included with the outdoor sensor. Please refer to these instructions for installation of this device. (Order item #1302026.)
Installing The Heater (cont'd)
If using a PLC signal for transmitting outdoor temperature information, Dip Switch #6 inside the heater on its microprocessor board must be in the "OFF" position. (Refer to the Typical Con­trol Wiring Diagrams section for more information on the heater's dip switches.)
If using a direct wired outdoor sensor for transmitting outdoor temperature information, Dip Switch #6 inside the heater on its microprocessor board must be in the "ON" position. (Refer to the Typical Control Wiring Diagrams section in this manual for more information on the heater's dip switches.)
Manual Charge Control
No additional devices are required for brick core charging if the charge level is to be set manually by the user. Since the heater comes factory preset for automatic charge control, Location 19 (L19) must be adjusted to manual control. Location 7 (L07) should also be adjusted so that both room and brick core temperature can be adjusted after the M button is pressed for a few seconds. (The installing electrical contractor or power company personnel will have more information on how to make these adjustments.)
REMOTE ROOM SENSOR (OPTIONAL)
7
All 2000 series room heating units come factory equipped with a built-in room temperature sensor. This sensor is installed in the electrical compartment on the right side panel of the heater, near the floor. In installations where it is desired to monitor temperature at another point in the room, a remote room temperature sensor may be used. If a remote sensor is installed, the built-in sensor is disconnected. The remote sensor will provide the room temperature information to the heater. With either option, current room temperature is dislayed on the heater's face plate. An installation instruction sheet is included with the remote room sensor. Please refer to these instructions for installation of this device. (Order item #1302024.)

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. The heater also contains functions related to power company control that are explained in a Supplemental Installer's Guide. This guide is only available to power company officials and factory certified installers.

INSTALLER'S FINAL CHECKOUT PROCEDURE
9
For cross reference to number coded components, refer to the Exploded View Diagram (Figure 18) and Heater Parts List in the Owner’s Manual.
____ 1. De-energize the electrical circuit(s) feeding the heater. Place the control circuit board (2) in the service
position by sliding it off its mounting screws and hooking it on these same screws using the eyelets provided on the front of the mounting plate (1). Inspect all field installed electrical connections to ensure they are tight and that all wires are routed correctly. Keep in mind that ETS devices run for long periods of time at high electrical loads. Poor or marginal electrical connections will cause the connection to overheat and fail.
Class II (low voltage) wiring or any wiring not rated for line voltage should never be installed in a line voltage area.
____ 2. Check the damper system to ensure the damper operates freely and that there is no debris in this area which
could inhibit its operation. To do so, manually press the damper lever extending from the damper assembly (34). Be careful not to bend the damper actuator (40). If the damper is not free, remove the blower and clean any debris from that area.
____ 3. Check the settings of the dip switches on the back of the control circuit board (2). In applications where the
heater is being controlled by the power line carrier transmitter, typically all dip switches will be set in the
“OFF” position. If using a hard wired outdoor temperature sensor for automatic charge control, set dip
switch 6 on the back of the circuit board (2) to the “ON” position. With manual charge control, dip switch 6 must be set to the “OFF” position. (The Supplemental Installer’s Guide provides more information on the dip switches.)
15
If manual charge control is being utilized, the data in Location 19 (L19) must be set to d02. It is the factory recommendation to also set the data in Location 7 (L07) to d02 so that both room and brick core temperatures can be adjusted after the M button is pressed for a few seconds. It may be necessary to unlock these locations to make the change. This is done by changing the data in Location 39 (L39) to d20. Remember to reset the lock when adjustments are complete.
____ 4. Energize the heater and check blower (37) operation. If the blower is operating, adjust the room temperature
set point below the actual room temperature. To make certain the blower will start in low speed, set the room temperature one degree above actual room temperature. To check to ensure the heater’s blower will operate in high speed, adjust the room temperature set point to at least five degrees above actual room temperature.
____ 5. 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). Refer to the Unit Identification Label on the lower left side panel of the heater for information on voltage and input wattage of the heater being installed. Use the Charging Circuit Amperage Draw table on the next page for reference to the correct amperage for the specific heater being installed.
Page 17
16
NOTE
____ 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).

(AMP draw is calculated by taking the total input wattage divided by the input voltage.
Allow +/- 5% tolerance at nominal input voltage.)
This label is important since the heater may be connected to more than one branch circuit.
____ 7. Check all other system controls for proper operation.
FIGURE 10
____ 8. De-energize the heater. Return the control circuit board (2) to its
original position. Install the painted front panel (18). To assist in aligning the front panel with the top panel (19) and to make it easier to install the front panel screws, lifting slots have been provided in the galvanized base tray (57), one at each end. Place the tip of a screwdriver in one of these slots and lift upward. (See Figure 10.) Install the screw. Do the same on the other end. Be sure to use the plastic grill guard when installing the screws to protect the grill (10) from being scratched. The grill guard should be removed after the installation. Energize the system.
____9. Present owner with the manual and warranty information. The
owner's registration card must be completed and returned to Steffes Corporation to ensure warranty coverage. The owner should retain the top portion of the card for their records. The installer should retain the Supplemental Guide.
____ 10. Take the time needed to instruct the owner on how to operate the system. Many service calls with new ETS
systems are a result of owner confusion on equipment operation. The time spent in training will greatly reduce the chance of a call back.

HEATER DIP SWITCH SETTINGS
5
The brick core charging of the 2000 series room heating unit is capable of being controlled by low voltage wiring, by line voltage wiring, by a time clock or by a power line carrier signal (wireless control) with the use of the Steffes power line carrier (PLC) control system.
Depending on which method of heating element control is being used, the unit configuration dip switches will need to be set accordingly. (See Figure 13 for location of these dip switches in the heater.) The function of each dip switch is as follows:
Dip Switch #1 = Invert Peak Signal (Should be "ON" if using a time clock for control purposes.) Dip Switch #2 = NOT USED (Should always remain in "OFF" position.) Dip Switch #3 = Invert Occupied/Not Occupied Signal (Room Temperature Set back) Dip Switch #4 = Invert Anticipated (Pre-Peak) Signal Dip Switch #5 = Enable Auxiliary Heat Call Feature Dip Switch #6 = Automatic Charge Control Configuration (Should be "ON" if a direct wired outdoor sensor is being
used for automatic brick core charge regulation.) Dip Switch #7 = Security (Editing Control) Mode Dip Switch #8 = Used for factory purposes ONLY. (Must always remain in "OFF" position.)
If the dip switch button is set in the up position, the dip switch is in the "ON" (activated) position. If the dip switch button is set in the down position, the dip switch is in the "OFF" (deactivated) position. (See Figure 13 for location of the dip switches in the heater.)

CAUTION
The data for the heaters operating functions are stored in specific locations in the heater's microprocessor and can be accessed through the control panel. All functions should be adjusted by the installer for the application at the time of the installation. The only adjustment the user should have to make is setting the room temperature which is typical with any heating system. If the ETS system has been set for manual charge control, the user will also need to adjust the brick core charge level on occasion.
Usually, the owner can access heater data stored in Locations 0 through 10 (L00 - L10) and can make adjustments if desired. When adjusting or viewing any of the heater data, the MODE digit will indicate an "L" or a "d".
L = Indicates the location of the heater function that is being viewed or changed. (See Figure 19.)
d = Indicates the specific data that is stored in a location. This data determines how the heater will

DESCRIBING THE HEATER FUNCTIONS (L00 through L10)
3
All heater functions relating to temperature will be reflected in Fahrenheit, even if the room
temperature display is set to read in Celsius. The Celsius equivalency to Fahrenheit is listed next to these temperature function descriptions for your reference. For a complete list of temperature conversions, refer to the Temperature Conversion Chart, Table 5, in this manual.
Location 0 (L00) - Room Temperature Set Point
This is the room temperature set point. This set point typically is not adjusted in this location but rather in the standard edit mode. The maximum value of this set point is dictated by the value in Location 8 (L08), and the minimum value is dictated by the value in Location 9 (L09).
Data Value Range: d00 to d99 (degrees Fahrenheit)
(Celsius equivalency: -17.8 to 37.2)
Refer to Adjusting the Room Temperature Set Point section of this manual for more information.

NOTE
NOTE
Location 1 (L01) - Brick Core Temperature Set Point
Advanced Heater Operation (cont'd)
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.
Data Value Range: d00 to d10
If Using Manual Charge Control: The data entered in this location indicates the targeted brick core
charge level for the room heating unit. It is factory preset at d05 (approximately 50% core charge).
Data Value Range: d00 to d10
d00 = -25% trim d10 = +25% trim
d00 = no core charging will occur d05 = 50% core charge will be maintained d10 = maximum core charge will be maintained
Refer to Adjusting the Brick Core Charging Level section in this manual for more information.
Location 2 (L02)
Presently, this location is not used. L02 is factory preset at d01 and should not be changed.
Location 3 (L03) - Display Illumination
This location is used to set the face plate's illumination status. Usually, the face plate is preset for continuous display of current room temperature. This can be changed so the face plate display goes blank after a few seconds of inactivity. L03 is factory preset at d00.
Data Value Range: d00 to d04
d00 = continuous illumination of the face plate d01 = display goes blank after a period of inactivity (less than
one minute)
d02, d03, d04 = currently, no function associated with these
values
Location 4 (L04) - Automatic Charge Control Start Charging Set Point
This location indicates the outdoor temperature at which the room heating unit should start brick core charging. L04 is factory preset at d60 (60oF which equates to 15.6oC).
Data Value Range: any value up to d90 (degrees Fahrenheit)
Only applicable if using Automatic Charge Control. Refer to Adjusting the Brick Core Charging Level section of this manual for more information.
Page 30
Advanced Heater Operation (cont'd)
NOTE
NOTE
NOTE
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).
Data Value Range: any value up to d90 (degrees Fahrenheit)
Only applicable if using Automatic Charge Control. If you are entering a negative data value into a location, the face plate will display a "-" (minus sign) rather than a "d" while in the edit mode. Refer to Adjusting the Brick Core Charging Level section of this manual for more information.
Location 6 (L06) - Room Temperature Set Back
This location indicates the number of degrees (oF) the room temperature set point will be reduced if a room temperature set back signal is received by the room heating unit. L06 is factory preset at d00.
Data Value Range: d00 to d65
This location should be preset by the installer during the installation procedure if the room temperature set back function is to be enabled in the application. It is the factory recommendation that the owner does not adjust this setting once it has been set.
29
Location 7 (L07) - Display Operation Mode
This location sets the display operation mode for room temperature and brick core temperature. L07 is factory preset at d00.
Data Value Range: d00 to d04
d00 = will allow for only room temperature setting adjustment
at any time.
d01 = will allow for only room temperature setting adjustment;
however, the M button must first be depressed for a few seconds
d02 = will allow for room and core temperature settings to be
edited after the M button is depressed for few seconds
d03, d04 = not recommended to be utilized
If using manual charge control, the data in this location should be set to d02.
Location 8 (L08) - Room Temperature - Maximum Value
This location is used to set the maximum room temperature set point. This set point is the highest temperature to which the room temperature thermostat can be adjusted. For example: If the data value in this location is set to d85, then 85oF will be the highest room temperature to which the thermostat can be adjusted. L08 is factory preset at d85 (85oF which equates to 29.4oC).
Data Value Range: d45 to d99 (degrees Fahrenheit)
(Celsius equivalency: 7.2 to 37.2)
Page 31
30
NOTE
NOTE
Location 9 (L09) - Room Temperature - Minimum Value
Location 10 (L10) - Room Temperature Display Calibration
Advanced Heater Operation (cont'd)
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. "OFF" will be displayed on the face plate. L09 is factory preset at d45 (45oF which equates to 7.2oC).
Data Value Range: d01 to d80 (degrees Fahrenheit)
(Celsius equivalency: -17.2 to 26.7)
This location allows for calibrating of the current room temperature value which is displayed. By entering a negative number into this location, the actual room temperature value displayed will be decreased by that number. By entering a positive number, the room temperature value displayed will be increased by that number. For example: The room heating unit could sense it is 68oF in the room; however, with a data value of d04 entered into this location, the face plate will display 72oF. Calibra­tion of the room temperature may vary from heater to heater and will be set at the factory.
Data Value Range: -20 to d20 (degrees Fahrenheit)
If you are entering a negative data value into a location, the face plate will display a "-" (minus sign) rather than a "d" while in the edit mode.
BRICK CORE OPERATING MODES: "C", "P", AND "A"
4
Typically, the face plate of the control panel will continuously display current room temperature. It will also display a "C" for charge, "P" for peak, or "A" for anticipated peak to indicate the current brick core operating mode (See Figure 21). The face plate can be set so these brick core charging modes are not displayed; but, rather, an "F" for Fahrenheit or "C" for Celsius is displayed after the room temperature (See Figure 22.)
These options can be preset to owner preference during the installation procedure when the heater operational functions are being set. The installing electrical contractor or power company personnel will have more information on how to change these functions in the heater.

NOTE
1. 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. Once the appropriate brick core charge level is reached, the heating elements will automatically turn off.
• The blower turns on when the room thermostat calls for heat and extracts heat from the brick core to maintain a constant, comfortable room tempera­ture.
• If the room thermostat calls for heat during a time when there is no heat stored in the brick core, the blower and heating elements will come on and begin releasing heat to the area until the heat call has been satisfied.
2. Peak Mode (On-Peak): See Figure 24
• MODE digit displays a "P".
• TEMPERATURE digits display actual room tem-
perature.
• During this mode, the heater is not allowed to store heat in the bricks. The heating elements will remain off for the duration of the on-peak period. (Excep­tion: If the utility company permits the use of the freeze protection and/or comfort override options, some element operation may occur. See below.)
• The blower turns on when the room thermostat calls for heat and extracts heat from the brick core to maintain a constant, comfortable room temperature.

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.
Freeze protection and peak override options may not be available in your area. Please consult your power company if you are unsure of whether these options are available to you.
Freeze Protection (power company permitting)
This feature is used to maintain a temperature above freezing in the area where the heater is located. 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 room temperature falls below the freeze protection temperature set point as programmed in the heater.
Page 33

3. Anticipated Peak (Pre-Peak) Mode: See Figure 25
Advanced Heater Operation (cont'd)
This mode is used only in specialiazed installations. You may not have this option enabled on your heating unit.
FIGURE 25
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. Once the signal is received, the room heating unit will charge to a level needed to satisfy the heating requirements of the area during the control period.
• MODE digit displays an "A".
• TEMPERATURE digits display actual room
temperature.
• During this mode, the heater is allowed to store heat in the brick core. If the brick core charge level 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. Once the appropriate brick core charge level is reached, the heating elements will automatically turn off.
• The heater can be set so that the blower comes on as the room thermostat calls for heat, or it can be set so that it cannot come on at all during an anticipated peak period. The heater can also be set so that there is limited blower operation during this time. Under some situations, limiting the amount of blower operation, or not allowing it to come on at all, may be necessary to ensure that the room heating unit will have an adequate amount of heat stored in the bricks for an upcoming peak control period.
