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
o F which equates to -6.7 o C).
Data Value Range: any value up to d90 (degrees Fahrenheit)
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
section of this manual for more information.
Location 6 (L06) - Room Temperature Set Back
This location indicates the number of degrees ( o 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
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
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
o F will be the highest room temperature to which the thermostat
can be adjusted. L08 is factory preset at d85 (85 o F which equates to 29.4 o C).
Data Value Range: d45 to d99 (degrees Fahrenheit)
(Celsius equivalency: 7.2 to 37.2)
