What is ETS?What is ETS?
What is ETS?What is ETS?
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 elec-
tricity 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 damper. Some radiant heat will be
given off by the heater's cabinet; however, most of the heating requirements in the area where the heater is
installed will be satisified by the heater's dampering system. When the room thermostat senses a need for
heat, the heater's damper will open. Heat is allowed to be extracted from the ceramic brick core to maintain
a constant, comfortable, room temperature.

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. 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 build up, 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 ETS recommends
using "Soft Scrub with Bleach" brand cleanser or its equal.
Regularly vacuum around all sides of the heater. No additional routine maintenance is required.

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.
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
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 auto-
matic 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 ñ arrow button to increase the set point or the ò 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 ñ arrow button or the ò arrow button to adjust the room temperature set point. The
face plate will automatically return to displaying current room temperature after making an adjust-
ment.
ADJUSTING THE BRICK CORE CHARGE LEVEL
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.
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 0oF (15. oC)
and to be at full brick core charge at 20oF (- . 7oC).
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 ò or ñ 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.
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"
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.
Setting the Heater to "OFF" and turning it back "ON" when Using Automatic Charge Control
Step 1 To turn the heater "OFF", use the ò 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 ñ arrow button to adjust room temperature to the desired set
point.

PLACEMENT
The room heating unit was designed to be mounted in one of two places: on the floor or up on the wall. If
installing on the floor, normally, standard flooring systems with any type of covering, i.e. wood floor, carpet,
linoleum, will be sufficient; but, heater weight must be considered. If in doubt, consult a building contractor or
an architect. (See Table 2 for weight and physical dimensions of room heating unit being installed.) If install-
ing the heater at a height above the floor, a special wall mounting bracket must be used. This wall mounting
kit does not come standard with the heater and must be ordered special. (Order item #119003 .)
MPORTANT: The heater must be securely attached to wall studs.
Since the intake grill for the room air is located at the bottom of the heater, caution should be exercised when
installing the heater on extremely thick carpet. Any contact with the intake grill could block the air passage
through the brick core and inhibit the heating capabilities of the room unit.
Avoid installing the heater near sources of extreme heat or cold so the built-in room temperature sensor can
sample proper room air temperature.
CLEARANCE REQUIREMENTS
Allow a minimum of 2 inches of clearance from the sides of the heater and a
minimum of 12 inches from the top of the heater. There is no back clearance
as the heater's back panel surface mounts to the wall. (See Figure 7.)
If enclosing the room heating unit in a wooden cabinet or recessing it into a
wall, allow 2 inches clearance on sides and 12 inches on top. Do not
enclose or otherwise obstruct access to the heater's front panel and the air
intake and discharge grills. Objects such as curtains, furniture, or bed
covers must be kept a minimum of 4 inches from all room heating unit
surfaces and 12 inches from the grills.
f there is less than a 12" 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
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.
Direct wired heaters can only be connected with one branch circuit. Conductors used for the connection of the
heater must be rated for a minimum of 75O C. To determine the correct wire size for the heating unit being
installed, refer to the Unit Identification Label located on the right side of the heater. (See Figure 10. Table 2
will also provide information on conductor sizing.)
Field wiring entering the heater must be routed so that it will not interfere with the heater’s
damper control system. Never install Class (low voltage) wiring or any wiring for that
matter in a line voltage area unless it is rated for line voltage.
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 groundingtype
and suitable for the load of the heater. See the Unit
Identification Label on the lower right side panel of
the heater to determine correct circuit size. (See
Figure 8 for cord and receptacle requirements.)
The room heater's cord has a plug as shown in Figure 8A. An adapter, as shown in Figure 8B, is
available for connecting three blade grounding type plugs to two slot receptacles. The green
grounding means extending from the adapter must be connected to a permanent ground, such as a properly
grounded outlet box as shown in Figure 8C. This adapter should not be used if a three slot grounded recep-
tacle is available.
Heating element (brick core charging) control wiring connections for all room heating units
The charging of the heater is capable of being controlled on-peak via low voltage wiring, a wireless power line
carrier signal, or with a time clock. Since the heater is capable of being fed with only one line voltage branch
circuit, line voltage control of the heater's charging is not possible. 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 of the heater to be included with the shipment of the heater.
If using low voltage control, all connections to the room heater's control circuit board must be routed through
the low voltage raceway using the factory installed wiring. Class II (low voltage) wiring should never enter
the line voltage compartment of this room heating unit. (See Figures 13 and 14.)
Never install any wiring in a line voltage area unless it is rated for line voltage.
If a Power Line Carrier Transmitter is being used for control of the room heating unit, low voltage connec-
tions to the heater are not necessary. Installation instructions for this method of control are provided with the
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
wires. An installation instruction sheet is included with the time clock. Please refer to these instructiosn for
installation of this device inside the heater.

ATTACHING THE HEATER TO THE WALL
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.
Step 3 Remove the galvanized front panel (18) by removing the screws that attach it to the heater.
Step 4 With the heater placed in its desired location, mark the wall through the two mounting holes in the
painted back panel (2 ). The mounting holes that are chosen MUST correspond to wall studs.
Step 5 Move the heater to the side. Drill 3/1 " holes into the studs where the wall is marked and move the
heater back into place.
Step 6 Located in the lower right side of the heater is a package containing hardware to mount the heater to the
wall. Using a 7/1 ” socket and a long extension use the lag bolts (4 ) to attach the heater to the wall.
Proceed to the Brick Loading section of this manual.
The lag bolts must attach to wood wall studs. ( f the wall is not a standard wood studded struc-
ture, alternate fasteners must be used to securely attach the wall bracket.) f the heater is being
installed at a height above the floor, a special wall mounting bracket must also be used in addi-
tion to the lag bolts. This wall mounting kit does not come standard with the heater and must be
ordered special. (Order item #1190036.)
BRICK LOADING
For cross reference to number coded components, see the Exploded View Diagram (Figure 15)
and the Heater's Parts List. Refer to Table 3 for the number of bricks required for each heater
model.
MPORTANT: The heater must be securely mounted to
the wall prior to brick loading.
Step 1 To catch brick debris, to protect the flooring, and for easy
clean-up of the installation, place the room unit's shipping box
in front of the heater before loading the brick.
Step 2 To facilitate loading brick row 1, pull the heating element up
and lay it down so it hangs out the front of the heater (leave
the wires attached).
Step 3 Install brick row 1 with the indented side of the brick facing
the front. (See Figure 9.)
Step 4 Adjust the heating element so that it is in its original vertical
position.
Step 5 Install brick row 2 with the indented side of the brick facing the back of the heater. (See Figure 9.)
nstall bricks carefully to avoid damage to the base insulation panels (39, 40, and 41) and to the
insulation (37) on the back side of the brick cavity.
Step 6 Reassemble the heater except for the painted front panel. Proceed to Setting the Method of Brick Core
Charge Control section of this manual.

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 0oF
(15. oC) and to be at a full core charge level at 20oF (- .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 infor-
mation, WIRELESS, to an unlimited number of 1000 series heater for automatic charge control. No direct
wiring to the heater is required with a PLC control system. The outdoor temperature information is transmit-
ted through the existing power line in the home or building. The heater's built-in receiver will pick up the
signals being transmitted through the power lines 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.
f using a PLC signal for transmitting outdoor temperature information, Dip Switch #6 inside
the heater on its control board must be in the "OFF" position. (Refer to the Typical Control
Wiring Diagrams section in this manual for more information on the heater's dip switches.)
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 #130202 .)
With a direct wired outdoor sensor, Dip Switch #6 inside the heater on its control 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
All 1000 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 installa-
tions 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 and is available from the factory in three different
configurations whereby one, two, or three heaters can be connected to one sensor. The number of heaters to be
controlled by one sensor must be specified at the time of order of the sensor. Current room temperature is
dislayed on the heater's face plate whether the built-in sensor or remote sensor is being used. An installation
instruction sheet is included with the remote room sensor. Please refer to these instructions for installation of
this device. (Order item #1302024.)

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. The heater also contains
functions related to power company control that are explained in a Supplemental Installer's Guide. This
guide is not shipped with the heater but may be obtained from the distributor or factory (with power com-
pany consent) and should only be made available to installing electrical contractors or to power company
personnel.
INSTALLER'S FINAL CHECKOUT PROCEDURE
____ 1. After the brick is loaded, be sure the heater is de-energized. Place the main circuit board (#43) 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 (#15).
____ 2. Inspect all field installed electrical connections to ensure they are tight. 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.
____ 3. Check that all wiring is routed correctly. The field installed wiring in the heater’s electrical compart-
ment must not be placed near the damper actuator (#11) or its linkage (#10).
Class II (low voltage) wiring or any wiring not rated for line voltage should never be
installed in a line voltage area.
____ 4. Check the damper system to make certain the damper (#9) at the top of the brick core cavity sets down
completely over the openings so that a tight seal is achieved. This is critical for optimum performance
of the heater.
____ 5. Check the settings of the dip switches on the back of the heater’s control circuit board (#43). In applica-
tions where the heater is being controlled by 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 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.)
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 adjustment is complete.

____ 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 amper-
age 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. Use the Charging Circuit Amperage Draw table below for reference to the
correct amperage for the specific heater being installed.
INPUT WATTAGE VOLTAGE AMP DRAW
1.32 120 11.0
1.8 240 7.5
2.7 240 11.25
(AMP draw is calculated by taking the total input wattage divided by
the input voltage. Allow +/- 5% tolerance at nominal input voltage.)
____ 7. Make certain all fuses and/or circuit breakers are labeled in the distribution panel.
____ 8. Return the main circuit board (#43) to its original position and install the heater’s painted front panel
(#12). 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.
____ 9. 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.

The brick core charging of the 1000 series room heating unit is capable of being controlled by low voltage
wiring, by a time clock or WIRELESS with the use of the Steffes Power Line Carrier (PLC) control system.
If using the wireless method, only one PLC system is needed in an installation; and, it can be mounted indoor
or outdoor. It will transmit the load management control switch signal through the entire power line system in
the home or building. In addition to controlling the heater, it will transmit outdoor temperature information
for automatic brick core charging. An installation procedure manual will accompany the 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 # = 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.)
f the dip switch button is set in the up position, the dip switch is in the "ON" (activated) position.
f 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.
