How to get/write "RoomTempCorr" on VRC720?

[rICTx-T1D]

Hi folks,

in files "015.e7c.csv" and other I found the following parameters: r;wi,,RoomTempCorr,Room Temp Correction,,,,3300,,,temp,,,Room Temp Correction r;wi,,OutsideTempCorr,Outside Temp Correction,,,,3600,,,temp,,,Outside Temp Correction

Now I try to read und write it from my vrc700 and and it in 15.ctlv2.csv and 08.hmu.csv. But it doesn't work. Because I can set the value in display as regular user, I think it must be possible to change it on ebusd.

With 3300 element was not found, with " r;wi,,RoomTempCorr,Room Temp Correction,,,,3300,,,temp,,,Room Temp Correction " element found but not valid position

hmu RoomTempCorrection = (ERR: invalid position for 3108b51403055700 / 00)

some info:
