Does anyone know if the new V19 (not the inverter version) can set a seperate heating temperature, that has nothing to do with the charging under temperature protection.

For example set start heating at 15C and set charge under temperature protection to 5C.

I found the picture underneath from the V19 inverter BMS, but don't not know if the Jk B2A24S20P or 30P V19 Version also have this set of parameters. (TMP Start heating and TMP stop heating)

Actually I have installed a JK B2A24S20P HC BMS where the start of the heating stops charging current, as there is only one parameter to set. TMP Start heating and TMP stop heating do not exist when I open the app.

Therefore the heating function is useless for me, as the controller shuts of when regeneration is used and the battery is cold.
I need to set a desired battery temperature independant of the charging under temperature protection.

After Mail Ping-Pong , I got an answer from JK.

The >=V19.05 should have this parameters , but it is only heating when the BMS measures more current (in or out) as the heater draws.
The >=V15 <V19.05 should also have this set of parameters, but heating starts only when charging under temperatur cut off ist reached, this does not any make sense to me, maybe this was "lost in translation".

My installed JK B2A24S20P HC is V11.
I got a newer JK B2A24S20P HC and a B2A24S30P HC , but do not know if they are V15, so I have to put them on a battery to see the version.
