I don't know what "C.P" might stand for in a HVAC control cabinet drawing. Could anyone have a quick look? I'm not an electrical engineer, but a translator. Not sure what electrical component is designated this way. All I know is that the system is manufactured by a Korean company named Kiturami Bumyang Air Conditioning Co., Ltd. Please, see the picture attached, item No.2. Sorry for poor quality, that's how it is in the manual.

  • \$\begingroup\$ My first thought was control processor, but that's #7. It seems to refer to the block directly above it, are they connection points? What do you think NFB means? \$\endgroup\$

  • \$\begingroup\$ They might be connection points, thanks for the idea... I guess NFB is a no-fuse breaker \$\endgroup\$

  • \$\begingroup\$ Connection Points sounds reasonable, they look like DIN rail terminals. NFB is possibly a breaker of some sort. \$\endgroup\$

It's not uncommon for the inlet breaker to be followed by breakers for each circuit, and the modules in the picture looks about the right size, so CP could be 'circuit protection'.

It could be either "Control Panel" or "Control Point". It looks like a screw terminal which could be used to connect a front control panel. It could also simply be control test points.
