Anticipated Peak ~ Used only by certain power
companies as an alternative method of storing heat in
the brick core.
Automatic Charge Control ~ Method of brick core
charge regulation where a sensor monitors outdoor
temperature to automatically adjust the brick core
temperature. Indicated by an "A" on the system display.
Brick Core Charge Level ~ The amount of heat that
is stored in the brick core.
Charge Period ~ Off-peak time in which the system
is allowed to store heat in its brick core. Indicated by an
"C" on the system display.
Control Panel ~ Contains the buttons to adjust and
the display to indicate system functions.
Control Period ~ On-peak time in which the system
is not allowed to store heat in its brick core. Indicated
by an "P" on the system display.
Edit Mode ~ Process of changing or viewing the
values in a microprocessor location. This is accom-
plished with the use of the M (mode) button, the
(up arrow) button, and the (down arrow) button.
Location (Function) ~ Where the specific operating
information of the system is stored. These locations
are part of the system microprocessor and are accessed
through the control panel. Displayed as an "L" on the
faceplate when in the edit mode.
Location Value ~ The specific information set and
stored in a location on the microprocessor which
defines system operation. A value for a specific
location is accessed through the control panel.

Manual Charge Control ~ Method of brick core
charge regulation where the owner must periodically
adjust the brick core temperature setting in relation to
the outdoor temperature.
Microprocessor ~ Device on the circuit board of
the system which stores and processes the informa-
tion for controlling the operation of the system.
Off-peak ~ The time during the day or night when
the power company can supply electricity more
economically and may offer a special incentive such
as a reduced electric rate or billing credits for the
electricity consumed during this time. Typically,
electrical usage is not controlled during an off-peak
time. (The system will provide heat to satisfy
comfort requirements during this time as well as
charge or store heat in its brick core.)
On-peak ~ The time during the day or night when
the power company experiences a high demand for
electricity. To limit demand, certain appliances are
controlled to avoid usage by them and/or a premium
for the electricity consumed during this time may be
charged to discourage electrical usage. (The system
is not allowed to charge or store heat in its brick core
during peak periods. Heating requirements are
satisfied by only the heat it has stored in its brick
core.)
Outdoor Sensor ~ Device that senses outdoor air
temperatures and communicates this information to
the Comfort Plus for automatic charge control.
Room Temperature Set Point ~ The targeted
room temperature the system is to maintain. If the
room thermostat senses a temperature below this
point, the heater's blower will come on and extract
heat from the brick core.
