What is the implication of having a TRV light on while operating the pump?

Having a TRV (Temperature Relief Valve) light on while operating the pump indicates that the pump is overheating. This is a critical issue because it suggests that the pump's temperature is exceeding safe operating limits, potentially leading to equipment failure or damage if not addressed promptly. Operating a pump at elevated temperatures can compromise the integrity of various components and result in operational inefficiencies. Monitoring the TRV light is essential for the safety and longevity of the equipment, and it typically serves as an indicator that corrective actions, such as reducing the load, ensuring proper cooling systems are functioning, or checking for other underlying issues, need to be taken to prevent further complications.
