192 -If the "Heater" assignment is selected, a low battery temperature signal is outputted to the relay (see [[Low temperature protection>>doc:Battery management systems.BMS Main 2\.1.3\. Configuration.3\.6 Battery protection.WebHome||anchor="HLowtemperatureprotection"]]) or a signal "Heater" (see [[Heater control>>doc:Battery management systems.BMS Main 2\.1.3\. Configuration.3\.6 Battery protection.WebHome||anchor="HHeatercontrol"]]).
235 +If the "Balancing series 2" assignment is selected, the relay is used to connect a balancing resistor to the cell series 2 (see section Series balancing).
