21 +== Features ==
22 +
23 +* new algorithms in the Charging/Discharging controller that allow to control the Charging/Discharging contactor independently from the Charging and Discharging signals (see the "Control - Charge/Discharge" section). The new "Independent" algorithms are preferred in the battery systems with one contactor.
24 +* selection of errors that cause reset of contactor control signals (see the "Control - Main contactor", "Control - Charge", "Control - Discharge", "Control - Charge/Discharge", "Control - Discharge (AUX)", "Control - Heater", "Control - Cooler", "Protections - General error", "Control - Charging status", "Control - Discharging status" sections)
25 +* new "Current limit error" which is set if the battery current exceeds the charging or discharging current limits (see the "Protections - Charge current limit" and "Protections - Discharge current limit" sections)
26 +* new parameter to select the method of calculating the battery voltage: sum the cell voltages or use the measured voltage before contactors (see the "Control - Common settings" section)
27 +* clearing the Discharging (AUX) signal if the cell voltage is too low (see the "Control - Discharge (AUX)" section)
28 +* new assignment "Close External 1" for the discrete inputs (see the "Signals - Input discrete signals - Assignments" section)
29 +* new assignment "External 1" for the discrete outputs and power switches (see the "Signals - Output discrete signals - Assignments" and "Signals - Power switches - Assignments" sections). The "External 1" output is directly controlled by the "Close External 1" command.

31 +== Improvements ==

33 +* rearrangements in the settings sections, which are made to simplify the setup process
