Schedule ...HeatingTemp read timeout error

[bajvoc]

Hi
I have Protherm boiler which is identified as Vaillant, by ebus.

...
2025-11-26 15:21:25.397 [bus notice] scan 08: ;Vaillant;BAI00;0502;3302
...
2025-11-26 15:21:26.412 [main notice] read scan config file vaillant/08.bai.csv for ID "bai00", SW0502, HW3302
...
2025-11-26 15:21:30.302 [bus notice] scan 15: ;Vaillant;E7f_2;0001;8002
...
2025-11-26 15:21:30.302 [update notice] sent scan-read scan.15 QQ=31: Vaillant;E7f_2;0001;8002

I can read almost everything, except schedule ...HeatingTemp. Intristingly schedule ...HeatingTime is read out correctly
I got read timeout error
