3. Anticipated Peak (Pre-Peak) Mode: See Figure 25
This mode is used only in specialiazed installations.
You may not have this option enabled on your
heating unit.
This mode of operation is used in situations where the
power company sends a signal to the equipment prior
to the possibility of a control (on-peak) period. Once
the signal is received, the room heating unit will charge
to a level needed to satisfy the heating requirements of
the area during the control period.
• MODE digit displays an "A".
• TEMPERATURE digits display actual room
temperature.
• During this mode, the heater is allowed to store heat
in the brick core. If the brick core charge level 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 appropri-
ate charge level. Once the appropriate brick core
charge level is reached, the heating elements will
automatically turn off.
• The heater can be set so that the blower comes on as the room thermostat calls for heat, or it can be
set so that it cannot come on at all during an anticipated peak period. The heater can also be set so
that there is limited blower operation during this time. Under some situations, limiting the amount
of blower operation, or not allowing it to come on at all, may be necessary to ensure that the room
heating unit will have an adequate amount of heat stored in the bricks for an upcoming peak control
period.
