5.3.4. Temperature
compensation
The Controller CIP has a temperature compensation function for adjusting the
float voltage of the rectifiers as a function of the temperature, in order to
optimize the charging of VRLA batteries and to prevent premature aging.
The temperature compensation slope can be adjusted by means of the S3 DIP
switch module. Refer to Figure 5.1, Table 5.1 and Table 5.4 for the switch
selection applicable to the desired temperature compensation slope.

(providing the probe is installed).
Note 3:
The “x” means that the position of that switch does not matter.
To enable the temperature compensation function, the required battery
temperature probe must be mounted on the battery and connected to
