Location 9 (L09) - Room Temperature - Minimum Value
This location is used to set the minimum room temperature set point. This set point is the lowest
temperature to which the room temperature thermostat can be adjusted. For example: If the data
value in this location is set to d45, then 45
o
F will be the lowest room temperature to which the thermo-
stat can be adjusted. When adjusting the room temperature set point below this setting, the heater will
be shut off. "OFF" will be displayed on the face plate. L09 is factory preset at d45 (45
o
F which
equates to 7.2
o
C).
Data Value Range:
d01 to d80 (degrees Fahrenheit)
(Celsius equivalency: -17.2 to 26.7)
Location 10 (L10) - Room Temperature Display Calibration
This location allows for calibrating of the current room temperature value which is displayed. By
entering a negative number into this location, the actual room temperature value displayed will be
decreased by that number. By entering a positive number, the room temperature value displayed will
be increased by that number. For example: The room heating unit could sense it is 68
o
F in the room;
however, with a data value of d04 entered into this location, the face plate will display 72
o
F. Calibra-
tion of the room temperature may vary from heater to heater and will be set at the factory.
Data Value Range:
-20 to d20 (degrees Fahrenheit)
If you are entering a negative data value into a location, the face plate will display a
"-" (minus sign) rather than a "d" while in the edit mode.
BRICK CORE OPERATING MODES: "C", "P", AND "A"
Typically, the face plate of the control panel will continuously display current room temperature. It will also
display a "C" for charge, "P" for peak, or "A" for anticipated peak to indicate the current brick core operating
mode (See Figure 21). The face plate can be set so these brick core charging modes are not displayed; but,
rather, an "F" for Fahrenheit or "C" for Celsius is displayed after the room temperature (See Figure 22.)

These options can be preset to owner preference during the installation procedure when the
heater operational functions are being set. The installing electrical contractor or power company
personnel will have more information on how to change these functions in the heater.
