Background and Identification
HEC-branded remote controls are commonly used for air conditioning systems. The HEC remote control models used for air conditioning systems typically include model numbers beginning with “AC-5620-xx.” The remote’s model number is typically printed either on the remote’s front face or on the back of the remote.
A remote control is a device that is capable of operating another device from a distance through the transmission of electrical signals. Originally invented around the turn of the twentieth century, early designs were capable of merely triggering a reaction in another object in a sort-of on/off capacity. Nikola Tesla, surpassing his contemporaries, as usual, held an exhibition in 1898 of a remote control device capable of driving a boat, a technology he named “teleautomaton.”
Today, remote control technology is used in nearly all electronics with some sort of connectivity functionality, reserving the name “remote control” for devices explicitly used for this purpose. Most consumer remote controls are used for televisions and their related equipment, cameras, garage doors/gates, appliances, video game consoles, and remote-controlled vehicles such as cars or drones. As such, the design of a remote control varies greatly based on its application, with complexity varying from a single button for a garage door, to an array of joysticks and bumper buttons as found on a video game controller.
HEC-branded remote controls include the name “HEC” printed in capital letters near the bottom of the remote’s front face.
