Slope Compensation Enable: The activation of the slope thermal compensation
function is automatically enabled if the controller detects the presence of an QS873A
(VT-Probe) configured for a thermal probe.
Low Temperature Compensation Enable: When enabled, this activates the low-
temperature slope thermal compensation and the low temperature attributes of slope
thermal compensation.
Low Temperature Limit: This sets the minimum temperature for which low
temperature thermal compensation is continued.
Nominal Temperature: This sets the reference temperature at which increases in
temperature above this reference temperature will result in the output voltage being
decreased at the slope selected by the user. Temperatures below the reference
temperature will result in the output voltage being increased at the slope selected by
the user.
Upper Temperature Limit: This sets the maximum temperature for which thermal
compensation is continued.
Step Temperature: This is the temperature at which float charging is terminated.
This signifies that the batteries are too hot and charging current is stopped in order to
cool the batteries. Once the battery strings have cooled by 10°C, thermally
compensated float charging is resumed.
Low Temperature Slope: This sets the slope for low temperature slope thermal
compensation.
Upper Temperature Slope: This sets the slope for the high temperature slope
thermal compensation.
