Carrier 33CSPREMLK01R Retrofit Kit

The Carrier 33CSPREMLK01R PremierLink Control Retrofit Kit is the verified 33CSPREMLK direct replacement designed for seamless integration into the Carrier Comfort Network (CCN). As a veteran-grade HVAC retrofit controller, this kit enables advanced DDC (Direct Digital Control) capabilities for older rooftop units (RTU), split systems, and water source heat pumps (WSHP). It supports up to three stages of gas heating or a combination of mechanical and electric heat, utilizing temperature compensated start logic to ensure set points are reached precisely by the scheduled occupancy time. Technicians can leverage the integrated economizer control for unoccupied free cooling and pre-occupancy purge to optimize indoor air quality. This CCN compatible controller is DCV ready (Demand Controlled Ventilation) when paired with CO2 sensors and interfaces directly with Navigator, ComfortVIEW, and Service Tool diagnostic software for streamlined configuration and local or remote monitoring of safety alarms.
