For any HVAC unit to perform its function efficiently, it requires a proper control system to regulate the operations of a heating or air conditioning system. Controls for HVAC systems cover a broad range of products like thermocouples, contractors, unit boards, etc., which carry out different functions based on the sources of supply. HVAC controllers typically receive signals from resistors and transmit them to a relay phase monitor board, allowing you to control the entire unit. These control tools also monitor indoor environmental factors such as humidity and temperature and allow for achieving and maintaining desired cooling or heating levels. However, the type of HVAC system determines the control sequence. At DK Hardware, you can find a range of HVAC control tools from popular brands that will make your job much easier.
