Steffes 2006 - Manual (Page 29)

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
Location 4 (L04) - Automatic Charge Control Start Charging Set Point
This location indicates the outdoor temperature at which the room heating unit should start brick core
charging. L04 is factory preset at d60 (60
o F which equates to 15.6 o C).
Data Value Range: any value up to d90 (degrees Fahrenheit)
Only applicable if using Automatic Charge Control. Refer to Adjusting the Brick
Core Charging Level section of this manual for more information.
