Carrier CRWINSTR001A00 Start Pack
The Carrier CRWINSTR001A00 Winter Start Pack is a critical field-installed accessory designed to ensure reliable compressor operation during low-ambient startup conditions. For technicians servicing Carrier rooftop units or split systems, this package functions primarily as a time delay relay for LPS bypass. By providing a fixed 180-second (3-minute) delay, it prevents the low pressure switch from causing nuisance trips when outdoor temperatures drop and refrigerant pressures have not yet stabilized. This ensures the system remains online during the initial low ambient cooling cycle without requiring manual resets or causing unnecessary downtime.
This OEM Carrier part is compatible with a wide range of equipment, including 3 to 10-ton units running Puron R-410A refrigerant and larger 7.5 to 25-ton commercial systems. The kit includes a position-sensitive 24V time delay relay and necessary 18 AWG wiring for a professional integration into the existing control circuit. By bypassing the safety circuit only during the startup phase, the Carrier CRWINSTR001A00 maintains system protection while enhancing performance in harsh winter environments.
Key Benefits:- Eliminates Nuisance Trips: Bypasses the low-pressure switch for 3 minutes to allow system pressures to stabilize.
- Broad Compatibility: Engineered for Carrier, Bryant, and Payne rooftop units and condensing systems (3–25 tons).
- R-410A & R-22 Optimized: Suitable for systems using modern high-pressure refrigerants or legacy R-22 setups.
- Contractor Grade: Includes OEM technical specifications for precise fitment and long-term reliability in commercial applications.
- Why is my unit tripping on low pressure during winter startup? In cold weather, refrigerant pressure may be too low to close the switch immediately; the CRWINSTR001A00 provides the necessary delay to solve this.
- Is the relay position-sensitive? Yes, the time delay relay must be mounted with the terminals facing upwards as per Carrier installation instructions.
- Which systems can use this start pack? It is designed for Carrier rooftop units (3-10 tons) and various split system condensing units up to 25 tons.
Item is Non Cancelable / Non Returnable
