Description

  • The Johnson Controls P70LB-1C Dual Pressure Control High/Low HVAC Switch is an industrial-grade, commercial-grade equipment component engineered specifically to ensure continuous high-and-low-side compressor protection across demanding commercial refrigeration and chiller infrastructure.
  • Fabricated from premium galvanized steel housing components and heavy-duty copper-alloy bellows, this high-performance component handles extreme system variables across a 100-500 PSIG high-side threshold with dual automated reset loops while permanently resisting contact arcing and diagnostic drift.
  • The innovative adjustable high/low differential mechanism significantly improves system control precision to smoothly handle sudden load shifts and refrigerant spikes without causing short-cycling or catastrophic system failures.
  • Ideal for licensed HVAC/R technicians, mechanical contractors, and facility maintenance supervisors, this durable dual-pressure switch features universal flare terminals and an easy-access parameter scale to rapidly execute clean, direct field installations, maximize overall energy efficiency, and permanently eliminate expensive equipment failure callbacks.
