Description
The Tecumseh 84174-1 SPST Dual Pressure Control is a safety and operating unit used in cooling systems to monitor both high and low pressure conditions of circuits. It switches electrical circuits based on pressure changes, assisting to protect the compressor from abnormal operating conditions such as low suction pressure or excessive discharge pressure. Used in condensing units, chillers, and packaged HVAC systems, it supports system protection, cycle control, and reliable operation. It is applied in commercial and residential ice maker systems where dual pressure monitoring and safe compressor operation are required.
