Calculated Maximum Float Voltage.  This is the maximum voltage that the system 

can adjust to given the temperature compensation slope, nominal float voltage and 

temperature compensation temperature limits.
Calculated Minimum Float Voltage.  This is the minimum voltage that the system 

can adjust to given the temperature compensation slope, nominal float voltage and 

temperature compensation temperature limits.
Enable Temperature Compensation check box.  If this box is checked, the system 

will apply temperature compensation to the float voltage.  If not, the system will 

always output the nominal float voltage unless equalization, testing or charge current 

limit is active.

The Battery tab allows data about the batteries attached to the system to be entered 

as below:

Number of cells.  This is used in the calculation of temperature compensation.  It 

is the total number of cells in one battery string (e.g. normally 24 cells for a 48V 

system with 2V per cell lead acid cells)
System voltage.  Choose from 12, 24 or 48V.
Number of Strings.  Number of strings of batteries attached to the system.  Note 

that X75 only allows connection of a single battery string and that this setting should 

therefore be 1 or 0 (if no batteries are connected).
