Carrier HN67QC006 Time Delay Relay, 1-20 Sec On / 40-90 Sec Off Delay

Description

The Carrier HN67QC006 is a purpose-built time delay relay designed to deliver precise sequencing control in HVAC systems. With an adjustable on-time delay of 1 to 20 seconds and an adjustable off-time delay of 40 to 90 seconds, this relay ensures that system components start and stop in the correct order — protecting equipment, reducing wear, and improving overall system reliability.

Key Features

• Adjustable on-time delay: 1–20 seconds
• Adjustable off-time delay: 40–90 seconds
• Genuine Carrier OEM replacement part
• Engineered for reliable HVAC system sequencing and component protection
• Helps prevent short-cycling and simultaneous component startup
• Direct replacement for compatible Carrier systems

Application

The HN67QC006 time delay relay is ideal for use in residential and light commercial Carrier HVAC equipment where controlled startup and shutdown sequencing is required. The on-delay function prevents components from energizing too quickly, while the off-delay keeps fans or other loads running for a set period after the primary control signal is removed — a common requirement for heat dissipation in furnaces, air handlers, and heat pump systems.

Why Choose a Genuine Carrier OEM Part?

Using a genuine Carrier OEM relay ensures compatibility with your existing equipment, maintains system warranty integrity, and delivers the performance specifications your system was designed around. The HN67QC006 is a direct drop-in replacement, minimizing installation time and eliminating the guesswork of aftermarket substitutions.
