Lennox 11B97 Weather Kit
The Lennox 11B97 Mild Weather Kit (612651-01) is an essential technical field-installed accessory designed to optimize heat pump performance during moderate outdoor temperatures. When operating in heating mode under mild conditions, internal head pressures can exceed standard operational parameters, leading to equipment stress. This OEM Lennox weather kit utilizes a precision-engineered mild weather pressure switch that automatically cycles the outdoor fan motor to regulate high-side pressure. By integrating this kit, contractors effectively eliminate nuisance high-pressure cutouts, ensuring consistent system uptime without manual intervention.
Specifically calibrated for HFC-410A and HCFC-22 systems, the kit includes a dual-compatibility pressure switch, a specialized valve depressor tee, and 12-inch protective conduit for secure HVAC wiring. The inclusion of the K159 relay (69J80) ensures seamless integration with high-efficiency Lennox XP17 and XP21 models. For technicians, this mild weather control is a critical upgrade to prevent compressor short-cycling and protect the long-term integrity of the outdoor fan motor and reversing valve during transitional seasonal weather.
Key Benefits
- System Reliability: Prevents unexpected shutdowns by managing head pressure before the primary high-pressure switch triggers.
- Universal Compatibility: Includes components for both R-22 and R-410A refrigerant applications.
- Advanced Protection: Reduces mechanical wear on the compressor by maintaining stable operating pressures in mild ambient heat.
- Complete Field Kit: Comes with a valve depressor tee, K159 relay, and protective conduit for a professional-grade installation.
- How does the Lennox 11B97 prevent high-pressure trips? The internal pressure switch monitors the vapor line and cycles the outdoor fan to keep head pressure within a safe range during mild outdoor heating demands.
- Is this kit compatible with non-Lennox heat pumps? This is a genuine Lennox OEM part designed specifically for Lennox-branded heat pumps and split systems.
- Does the 11B97 kit include the necessary wiring? Yes, the package includes the K159 relay, 18-gauge wires, wire nuts, and a protective conduit for full integration.
