DESCRIBING THE HEATER FUNCTIONS (L00 through L10)
All heater functions relating to temperature will be reflected in Fahrenheit, even if the room
temperature display is set to read in Celsius. The Celsius equivalency to Fahrenheit is listed
next to these temperature function descriptions for your reference. For a complete list of
temperature conversions, refer to the Temperature Conversion Chart, Table 4, in this manual.
Location 0 (L00) - Room Temperature Set Point
This is the room temperature set point. This set point typically is not adjusted in this location but
rather in the standard edit mode. The maximum value of this set point is dictated by the value in
Location 8 (L08), and the minimum value is dictated by the value in Location 9 (L09).
Data Value Range:
d00 to d99 (degrees Fahrenheit)
(Celsius equivalency: -17.8 to 37.2)
Refer to Adjusting the Room Temperature Set Point section of this manual for
more information.
Location 1 (L01) - Brick Core Temperature Set Point
If Using Automatic Charge Control: The data entered into this location provides a trim adjustment
to brick core temperature. As the heater charges automatically in relation to outdoor temperature,
this trim will either increase (up by +25%) or decrease (down by -25%) brick core temperature. If
you do not desire to use the trim function, this should be set at d05. L01 is factory preset at d05.
Data Value Range:
d00 to d10
d00 = -25% trim
d10 = +25% trim
If Using Manual Charge Control: The data entered in this location indicates the targeted brick
core charge level for the room heating unit. It is factory preset at d05 (approximately 50% core
charge).
Data Value Range:
d00 to d10
d00 = no core charging will occur
d05 = 50% core charge will be maintained
d10 = maximum core charge will be maintained
Refer to Adjusting the Brick Core Charging Level section in this manual for more
information.
Location 2 (L02)
Presently, this location is not used. L02 is factory preset at d01 and should not be changed.
Location 3 (L03) - Display Illumination
This location is used to set the face plate's illumination status. Usually, the face plate is preset for
continuous display of current room temperature. This can be changed so the face plate display goes
blank after a few seconds of inactivity. L03 is factory preset at d00.
Data Value Range:
d00 to d04
d00 = continuous illumination of the face plate
d01 = display goes blank after a period of inactivity (less than
one minute)
d02, d03, d04 = currently, no function associated with these
values
