1. Charge Mode (Off-Peak): See Figure 23
• 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 blower turns on when the room thermostat
calls for heat and extracts heat from the brick core
to maintain a constant, comfortable room tempera-
ture.
• If the room thermostat calls for heat during a time
when there is no heat stored in the brick core, the
blower and heating elements will come on and
begin releasing heat to the area until the heat call
has been satisfied.
2. Peak Mode (On-Peak): See Figure 24
• MODE digit displays a "P".
• TEMPERATURE digits display actual room tem-
perature.
• 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. (Excep-
tion: If the utility company permits the use of the
freeze protection and/or comfort override options,
some element operation may occur. See below.)
• The blower turns on 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 (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.

Advanced Heater Operation
(cont'd)
Freeze protection and peak override options may not be available in your area. Please consult
your power company if you are unsure of whether these options are available to you.
