Preventing overheating or overpressure (by draining the working fluid F24S40/60)

Introduced: January 2018

Title

Titles differ between systems:

IPC: Preventing overheating or overpressure

CPC: Preventing overheating or overpressure (by draining the working fluid F24S40/60)

Full Title

Full titles differ between systems:

IPC:

Safety or protection arrangements of solar heat collectors; Preventing malfunction of solar heat collectors > Preventing overheating or overpressure

CPC:

Safety or protection arrangements of solar heat collectors; Preventing malfunction of solar heat collectors (control arrangements F24S50/00) > Preventing overheating or overpressure (by draining the working fluid F24S40/60)

IPC and CPC are identically structured here. All 5 subcodes exist in both systems.

2 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 2018.
