Description
The Bosch HVAC 87377002890 Sensor is a temperature-sensing component used in heating and cooling systems, typically in boiler or hydronic control applications. It measures supply temperature and sends resistance-based signals back to the control board for regulation of heating or cooling performance. Commonly installed in tankless water heaters and hydronic units, it is positioned on or near the water line or heat exchanger to monitor operating conditions. Within the system, the sensor operator is a feedback part that supports maintaining an accurate temperature HVAC system.
