hours are available, the system converts electricity to heat which is then stored

in its ceramic brick core. The amount of heat stored in the brick core varies in

relation to outdoor temperature, owner preference, utility peak conditions, and

the heating requirements.

A heat call from the room thermostat energizes the blowers in the Comfort Plus system. The variable speed core

blower(s) automatically adjust its speed to circulate room air through the brick core. The supply air blower then

delivers this heated air into the desired area through the duct system to maintain a constant, comfortable room tem-

perature.

perienced. Also, if not used for an extended period of time, dust may accumulate in the system. Allow the Comfort

Plus heating system to charge to its maximum brick core charge level to expel odors in a timely manner.

As with most heating systems, air borne particles and odors in the room may be drawn into the Comfort Plus and

oxidized. Odors can be amplied; thus, it is not recommended to operate the system if odors such as those

from paints, varnishes, or chemicals are present in the air. Air borne particles, which have been oxidized, are

expelled back into the room and may accumulate on air vents 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 aerosols,

dust, candles, incense, pet hair, smoke, or cooking can contribute to poor indoor air quality and accelerate the soot-

ing process.

During operation, the Comfort Plus heating system may produce minor expansion noises. These noises are the

result of the internal components reacting to temperature changes.

TURNING SYSTEM "OFF" AND "ON"

The Comfort Plus element (charging) circuits may be turned “OFF” by switchingALL of the 60AMP breakers

located on the front of the electrical panel to the DOWN position. To turn the element circuits “ON”, switch ALL

of the 60 AMP breakers to the UP position.

NOTE: The 15AMPbreaker MUST remain “ON” to operate controls in the system if:

• using the Comfort Plus in conjunction with a heat pump or air conditioner.

• using the Comfort Plus to control other loads.

• using the optional Stees Time Clock Module.

operation of the system.

CONTROL PANEL

NOTE:

Comfort Plus Operation 1.03

ROOM TEMPERATURE CONTROL

The room temperature set point is adjusted at the wall thermostat. If room temperature drops below the thermostat

set point, the thermostat initiates a heat call and energizes the blowers in the Comfort Plus heating system. The

variable speed core blower(s) automatically adjust speed in relation to brick core temperature and duct temperature

to circulate room air through the brick core. The supply air blower then delivers the heated air into the living area

through the duct system to satisfy heating requirements. When the thermostat senses a demand greater than the

output, another stage of heating is initiated.

When used to supplement heat pump systems, the Comfort Plus replaces the resistance strip heat, which is

typically required as a supplement or back-up to the heat pump system. A duct sensor monitors the discharge

air temperature. If the demand for heat is at a point where the heat pump alone cannot maintain the desired duct

temperature, stored heat is used to supplement the heat pump and satisfy the heating requirements.

BRICK CORE CHARGE CONTROL

The amount of heat stored in the brick core of the Comfort Plus system is regulated automatically in relation to

outdoor temperature and the heating requirements. The outdoor sensor, supplied with the system, monitors outdoor

temperature and provides this information to the Comfort Plus. As the outdoor temperature decreases, heating

requirements increase and the system stores more heat accordingly.

CHARGE CONTROL OVERRIDE

The Comfort Plus is equipped with a charge control override feature that allows the user to force the system to

target a full core charge level. This override can be initiated or cancelled at any time. If an override is initiated,

PLACEMENT AND CLEARANCE REQUIREMENTS

The physical dimensions of the Comfort Plus, along with the

clearances required, MUST be taken into consideration when

choosing its location within a structure. (See Figures 1 and 2 for

clearance requirements and system dimensions.)

The best installation location for this system is in a space

requiring heat so some amount of the heating requirements can

In situations where the Comfort Plus is not installed in an area it

is intended to heat (i.e. storage closet), it is important to account

for the heat lost through static dissipation by making proper

adjustments when sizing the system. Standby heat dissipation of

up to 2.5kW can be experienced in normal operation. Room air

should be maintained at less than 85° F/ 29° C.

If ventilation is needed, it can be provided by installing a 24” x

24” opening into the area where the Comfort Plus is located. In

addition, a 6” x 6” non-closing type register can be cut into the

return air duct of the furnace to minimize heat build-up in the

room. This register must be installed in a manner that ensures the

Risk of re. Can cause injury or death.

• Violation of the clearance

requirements and/or failure to

provide proper ventilation can cause

improper operation of the system.

Maintain the placement and clearance

requirements as specied and provide

ventilation as necessary.

• Failure to maintain room temperature

in the mechanical room of 85o F/

29oC or less may result in equipment

damage. Thermostatically controlled

ventilation should be provided if the

temperature in this area exceeds 85o

F/ 29oC.

• Moving the system after install may

result in equipment damage. Do NOT

move system from original installed

location.
