Carrier KAATD0101TDR Kit

The Carrier KAATD0101TDR Time Delay Kit is an essential field-installed component engineered to optimize the performance of residential and commercial split system air conditioners and heat pumps. This HVAC time delay relay functions by permitting the indoor fan motor to continue operating for approximately 90 seconds after the compressor cycles off. By utilizing the residual cooling capacity remaining in the evaporator coil, this kit effectively increases the SEER rating and overall energy efficiency of the system without the need for extensive hardware overhauls.

Designed for seamless integration into Carrier, Bryant, and Payne equipment, the KAATD0101TDR operates on a 24V control circuit. It serves as a critical defense against compressor short cycling, which can occur during rapid thermostat adjustments or brief power interruptions. This kit includes the relay, mounting hardware, and standard color-coded wiring (Red, Brown, Black, Orange) for straightforward installation on the low-voltage terminal board of a furnace or fan coil. As a veteran-grade OEM replacement part, it ensures timing accuracy and long-term reliability in demanding thermal environments.

• Enhances Efficiency: Maximizes sensible cooling by exhausting remaining cold air from the coil after cycle completion.
• Protects Compressor: Prevents premature failure by eliminating rapid short cycling during pressure equalization.
• OEM Compatibility: Specifically designed for 24V control systems in Carrier and Bryant legacy and current models.
• Simple Integration: Features a standard 5-wire interface for fast terminal board connections.

• What does the delay interval provide? The 90-second delay allows the fan to leverage the cold refrigerant remaining in the coil to provide additional cooling at no extra compressor cost.
• Is this compatible with all thermostats? Yes, it functions with standard 24V thermostats by intercepting the G-call to manage fan timing independently of the unit board.
• Where is it physically installed? The relay is typically mounted inside the furnace or fan coil cabinet using the provided self-tapping screws.
