In this clip, guest expert Steve Cook from Hisense breaks down how communicating systems work in modern HVAC equipment. He covers: The need for DC signals to communicate between components like compressors, inverters, and thermistors to optimize efficiency How each brand uses its own communication "protocol" or language that components must follow The language barrier between different brands' protocols Get valuable insights into the inner workings of communicating HVAC systems and the role of DC signals and protocols from Steve's experience in the field. #HVACSchool #HVACCommunicatingSystems #DCSignals #CommunicationProtocols
