Review LOCHINVAR Fits Nl Outlet Sensor/high Limit

The Lochinvar Tsds959 02-23 NL Outlet Sensor/High Limit is a crucial component in ensuring the safe and efficient operation of your heating system. This sensor is specifically designed for use with Lochinvar's NS Series Boilers and Water Heaters.

The Tsds959 02-23 NL Outlet Sensor/High Limit is a two-in-one device that serves both as an outlet temperature sensor and a high limit safety switch. The outlet temperature sensor measures the temperature of the water leaving the boiler or water heater, providing important feedback to the system's control module. This information is used to maintain the desired temperature and ensure optimal performance.

The high limit safety switch function is designed to protect against overheating, which can cause damage to the heating system or pose a safety risk.
