Steffes 8188 - Manual (Page 5)

GENERAL OPERATION
The ThermElect heating system stores off-peak electricity in the form of heat. Off-peak electricity is available
during times of the day or night when electricity is plentiful and the associated costs are low.
Operation of the heating system is automatic. During off-peak hours, the system converts electricity to heat which
is then stored in its ceramic brick core. The amount of heat stored in the brick core of the Storage Module(s)
varies in relation to outdoor temperature, current building load, utility peak conditions, and/or the heating require-
ments.
A heat call from the thermostat or main system control energizes the blowers in the system. The variable speed
core blower automatically adjusts its speed to circulate air through the brick core. The supply air blower then
delivers the heated air into the desired area through the duct system to maintain constant, comfortable temperature.
The versatility of this system allows it to fit many applications. The system is designed for use as either a sole
heating source (“stand alone” furnace) for make up air heating or as a supplement to another ducted heating
system such as a heat pump.
SYSTEM USE DURING CONSTRUCTION PHASE
Like most heating equipment manufacturers, Steffes strongly recommends that “Construction Heating Units” be
used instead of the permanent heating system during the construction phase. Use of the permanent heating system
during this phase may contaminate the duct system and/or internal areas of the heating system. This may cause
poor indoor air quality issues and/or improper system operation or equipment damage.
SYSTEM START-UP
On start-up of the system, odors relating to first time operation of the heating components may be experienced.
Also, if not used for an extended period of time, dust may accumulate in the system. Allow the 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 may be drawn into the system and oxidized. Odors
can be amplified; 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 sooting
process.
During operation, the 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 system is fully automatic and does not need to be manually disabled. Talk to your installer or energy manage-
ment person for additional information.
