Description
The Johnson Controls GM204-MH00 Refrigeration Sensor is a monitoring device used to detect and transmit temperature or pressure-related data within cooling equipment. In HVAC systems it is installed in refrigeration circuits, chillers, and air conditioning units where accurate sensing is required for controlled operation and system protection. Designed for use with R454A A2L refrigerant applications, it helps track operating conditions and provides input signals to the control system for regulation of cooling performance. The sensor plays a role in maintaining stable operation by supplying real-time data used for system adjustments.
