Description
The Tecumseh 84172-1 Low Pressure Control monitors refrigerant pressure and switches its electrical contacts when the sensed pressure reaches the control setting. This switching action allows the connected control circuit to regulate compressor operation during low-pressure conditions. Installed within the refrigeration circuit, it interfaces with compressor controls and connected electrical wiring in HVAC systems. The control provides pressure-responsive operation for compatible refrigeration equipment and maintains the intended electrical sequence during changing system conditions. It enables compressor protection, controlled cycling, pressure monitoring, and coordinated refrigeration operation.
