Where is voltage information for HVAC control systems usually shown?

Voltage information for HVAC control systems is typically found on HVAC wiring diagrams because these diagrams provide detailed representations of the electrical connections and components within the system. They illustrate how different parts of the system are interconnected, including power sources, control circuits, and the voltages used for operation.

HVAC wiring diagrams are an essential tool for electricians and technicians, allowing them to understand the electrical requirements of the system at a glance, including any voltage specifications necessary for proper installation and troubleshooting. This information is critical for ensuring that the system operates safely and efficiently, aligning with industry standards.

While project summary reports and equipment specification sheets contain useful information regarding the overall project and specific equipment details, they typically do not provide detailed wiring and voltage information. Additionally, while some voltage information may be noted on control panel exteriors, this is usually limited to labeling for easy reference rather than detailed specifications necessary for installation or troubleshooting.
