Automatic Charge Control Method of brick core charge regulation where a sensor monitors outdoor
temperature to automatically adjust the brick core temperature setting in relation
to the outdoor temperature.
Brick Core Charge Level The amount of heat that is stored in the heater’s brick core.
Charge Period Off­peak time in which the furnace is allowed to store heat in its brick core.
Control Panel Contains the toggle switches to adjust and display lights to indicate furnace
operation. Located on the lower front of the furnace on the electrical panel.
Control Period On­peak time in which the furnace is not allowed to store heat in its brick core.
Heat Call When room temperature falls below the room’s thermostat setting, the thermo­
stat signals the furnace to operate its blowers and deliver warm air into the
space to raise the temperature to the desired thermostat set point.
Heat Exchanger Device in the base of the furnace where the stored heat from the brick core
transfers to the duct system for delivery into the living space.
Manual Charge Control Method of brick core charging regulation where the user must periodically adjust
the brick core temperature setting in relation to the outdoor temperature.
Off­Peak 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,
uncontrollable electrical usage is allowed during this time. (Furnace is allowed
to charge or store heat in its brick core during this time.)
On­Peak 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. (Furnace is not allowed to charge or store heat in its
brick core during this time.)
Outdoor Temperature Sensor Device that senses outdoor air temperature and communicates this information
to the furnace for automatic charge control.
Peak Override Enables electrical usage in a device that is typically controlled by the power
company during an on­peak time. Some power companies may never permit
any controlled devices to be used during an on­peak time. Others that do may
penalize the user by charging a premium on energy consumed during this period.
