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.

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 CleaningMaintenance 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.

Describing Describing

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:

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)

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

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 adjustment.

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 60 and to be at full brick core charge at 20

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:

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 installing 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 #1190036.)

IMPORTANT: 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.

If there is less than a 12" clearance on the right side of the room heating unit, we recommend

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 75 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

CAUTION

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 receptacle 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.)

CAUTION

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 connections 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.

(15.6 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 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 transmitted 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.

If 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.)

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.)

NOTE

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 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 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.)

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 company 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).

NOTE

____ 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.)

NOTE

Class II (low voltage) wiring or any wiring not rated for line voltage should never be installed in a line voltage area.

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.

Page 16

____ 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. Use the Charging Circuit Amperage Draw table below for reference to the correct amperage for the specific heater being installed.

____ 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 #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.)

NOTE

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.

The room heating unit is shipped from the factory preset with standard operating functions.

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".

Adjustments should not have to be made; however, if you find it is necessary to do so, this section contains the information for changing the standard configuration. Please proceed with caution when making the adjustments.

L = Indicates the location of the heater function that is being viewed or changed. (See Figure 16.)

d = Indicates the specific data that is stored in a location. This data determines how the heater will

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 4, in this manual.

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).

NOTE

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.

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).

NOTE

Refer to Adjusting the Room Temperature Set Point section of this manual for more information.

Data Value Range: d00 to d10

d00 = -25% trim d10 = +25% trim

Data Value Range: d00 to d10

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)

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).

NOTE

Location 6 (L06) - “NOT OCCUPIED” Room Temperature Set Back

This location indicates the number of degrees (oF) the room temperature set point will be reduced if a “NOT OCCUPIED” signal is received by the room heating unit. L06 is factory preset at d00.

Only applicable if using Automatic Charge Control. Refer to Adjusting the Brick Core Charging Level section of this manual for more information.

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.

Data Value Range: d00 to d65

This location should be preset by the installer during the installation procedure if

NOTE

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.

NOTE

the “NOT OCCUPIED” 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.

Data Value Range: d00 to d04

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 85 thermostat can be adjusted. L08 is factory preset at d85 (85oF which equates to 29.4oC).

Data Value Range: d45 to d99 (degrees Fahrenheit)

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 7.2

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 specifically for each heater at the factory.

NOTE

EXPLAINING THE BRICK CORE OPERATING MODES:

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.

"C", "P", AND "A"

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 18). 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 19.)

These options can be preset to owner preference during the installation procedure when the

Room Temperature and Brick Core Operating Mode Peak Displayed

1. Charge Mode (Off-Peak): See Figure 20

• 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 damper opens 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 damper will open and the heating elements will come on. Heat will be released to the area until the heat call has been satisfied.

2. Peak Mode (On-Peak): See Figure 21

• MODE digit displays a "P".

• TEMPERATURE digits display actual room temperature.

• 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 damper opens 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

NOTE

consult your power company if you are unsure of whether these options are available to you.

3. Anticipated Peak (Pre-Peak) Mode: See Figure 22

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. 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.

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.

• 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 damper opens 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 damper operation during this time. Under some situations, limiting the amount of damper operation or not allowing it to open 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.
