In HPSU.py the logic on "commands" require them to be defined with all nibble uppercase (e.g. if command[6:8] != "FA").
the file etc/pyHPSU/commands_hpsu.csv has a last row with some lowercase nibble
t_flow_cooling;61 00 fa 03 dd 00 00;190;d;10;w
this should be
t_flow_cooling;61 00 FA 03 DD 00 00;190;d;10;w
