Begin with the ladder diagram, because it’s simplest to read. Reading these diagrams correctly isn’t necessarily the main section of an HVAC repair person’s job, but it is extremely important. With a tiny bit of practice, you will have the ability to make simple diagrams.
Each switch needs to be in a place to operate the loads. It must be able to operate the loads. Switches will appear basically the exact same on simple diagrams.

If there’s more than one START device, it’s typically put in parallel with the others. The input devices are set on the rungs in a manner that indicates the present flow through the rung whenever there is a comprehensive path to the outputs. There are many ways in which these input devices can be put on the rungs, although as stated earlier, they are usually set on the left side. Unlike input devices, it’s essential that the output devices only be set in parallel.
Refrigeration methods require operating controls so that they can cycle on and off to maintain a particular temperature. These systems are going to have the components split from one another and connected via wiring and a refrigeration line collection. It is generally a modular system of metal pipes or tubes, though it can be from different materials.
