Xylem-McDonnell & Miller PSE-801-M-120 Low Water Cut-Off M/R W/Standard Probe 120V 153601

The Xylem-McDonnell & Miller PSE-801-M-120 120V M/R W-Std Probe 153601 is an essential component of many HVAC systems, particularly hydronic heating boilers and chilled water systems. It detects variations in the water's temperature inside the system and acts as a temperature sensor. HVAC equipment can benefit from the Xylem-McDonnell & Miller PSE-801-M-120 probe in many ways by precisely monitoring water temperature. In permitting the boiler or chiller to maintain constant water temperatures, and increase efficiency, while minimizing overheating or underheating, he guarantees optimal system performance, the probe is essential to safety features since it activates shut-off mechanisms if the water temperature rises too much, protecting the equipment from possible harm.
