Allied Air 47k14 Time Delay Relay

Product Description

The ALLIED AIR 47k14 is a time delay relay designed for use in forced-air heating and cooling systems. Time delay relays control the sequencing of system components — such as blower motors and heating elements — by introducing a timed pause between electrical signals. This prevents short-cycling, reduces mechanical stress on motors, and helps the system operate within designed airflow and temperature parameters. The 47k14 is installed by licensed HVAC technicians as part of routine service or system repair.

This relay is suited for residential forced-air applications where timed sequencing of blower or auxiliary components is required. It functions as a control-circuit component, typically wired into the low-voltage or line-voltage control board circuit depending on the system configuration. Systems requiring proper blower-on or blower-off delay timing are the primary application.

Key Features

• Provides timed delay sequencing to protect blower motors and auxiliary components
• Reduces mechanical stress caused by abrupt starts and stops
• Functions as a direct service replacement for the original relay
• Compact form factor suited for control compartment installation

Compatibility

Designed as an OEM-style replacement time delay relay for residential forced-air heating and cooling systems requiring timed blower or component sequencing.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect all power to the unit at the breaker before removing or installing the relay. Verify correct wiring terminal orientation against the existing wiring layout before energizing the system. Follow applicable local electrical codes and manufacturer wiring diagrams during installation.
