Carrier HN67XZ210 Time Delay Relay

The Carrier HN67XZ210 time delay relay is a usage for the operation of multiple HVAC systems and also, to protect your equipment. A little but powerful switch brings the system’s electrical circuit to a controlled pause. This time delay relay is about 2" long and wide, and 1.25" tall. Carrier works by adding a time lag between the activation signal and the activation of other components in your Carrier unit. There can be several reasons why this delay is essential. In furnaces, it can maintain the proper ignition sequence, or allow heat exchangers to reach the proper temperature before starting a blower.
