Describing the Heater Functions (L00 through L10) - 2000 Series

NOTE: 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.

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)

NOTE: Refer to Adjusting the Room Temperature Set Point 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

d01 =

+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

NOTE: Refer to Adjusting the Brick Core Charging Level 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°F which equates to 15.6°C).

Data Value Range: any value up to d90 (degrees Fahrenheit)

NOTE: Only applicable if using Automatic Charge Control. Refer to Adjusting the Brick Core Charging Level for more information.

Location 5 (L05) - Automatic Charge Control Full Charge Set Point

This location indicates the outdoor temperature where the room heating unit should have a full brick core charge. Example: If Location 4 (L04) has a value of d60 and Location 5 (L05) has a value of d20, the room heating unit will take a proportional charge at any outdoor temperature between these two set points. L05 is factory preset at d20 (20°F which equates to -6.7°C).

Data Value Range: any value up to d90 (degrees Fahrenheit)

NOTE: Only applicable if using Automatic Charge Control. 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. Refer to Adjusting the Brick Core Charging Level for more information.

Location 6 (L06) - Room Temperature Set Back

This location indicates the number of degrees (°F) the room temperature set point will be reduced if a room temperature set back signal is received by the room heating unit. L06 is factory preset at d00.

Data Value Range: d00 to d65

NOTE: This location should be preset by the installer during the installation procedure if the room temperature set back function is to be enabled in the application. It is the factory recommendation that the owner does not adjust this setting once it has been set.

Location 7 (L07) - Display Operation Mode

This location sets the display operation mode for room temperature and brick core temperature. L07 is factory preset at d00.

Data Value Range: d00 to d04

d00 =

will allow for only room temperature setting adjustment at any time

d01 =

will allow for only room temperature setting adjustment; however, the M button must first be depressed for a few seconds

d02 =

will allow for room and core temperature settings to be edited after the M button is depressed for few seconds

d03, d04 =

not recommended to be utilized

NOTE: If using manual charge control, the data in this location should be set to d02.

Location 8 (L08) - Room Temperature - Maximum Value

This location is used to set the maximum room temperature set point. This set point is the highest temperature to which the room temperature thermostat can be adjusted. For example: If the data value in this location is set to d85, then 85°F will be the highest room temperature to which the thermostat can be adjusted. L08 is factory preset at d85 (85°F which equates to 29.4°C).

Data Value Range: d45 to d99 (degrees Fahrenheit)

(Celsius equivalency: 7.2 to 37.2)

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°F will be the lowest room temperature to which the thermostat 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°F which equates to 7.2°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°F in the room; however, with a data value of d04 entered into this location, the face plate will display 72°F. Calibration 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)

NOTE: 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.
