Allied Air 85w66 2-stage Compressor Relay Kit

Product Description

The ALLIED AIR 85w66 is a 2-stage compressor relay kit designed for use in residential and light commercial HVAC systems. This relay kit provides the switching control necessary to sequence compressor staging operations, allowing the system to modulate capacity based on load demand. It is a direct-service component installed by licensed HVAC technicians during system repair or maintenance when the original relay assembly has failed or requires replacement.

This kit is suited for 2-stage cooling or heating systems where staged compressor operation is required for efficiency and comfort control. It is typically installed in the control circuit of a split-system or packaged unit that uses two-stage compressor sequencing. The kit format means all necessary relay components are included for a complete service replacement.

Key Features
