Coolant sensors type ST4 — is designed to measure the temperature of the coolant in an analog way, changing the internal resistance depending on the temperature.

— installed on the boiler supply and return, in the DHW boiler sleeve, used in the system for protecting the pellet burner from overheating of the fuel supply unit, and also used in the storage tank at the top and bottom points of the tank.

— when working with a mixer, a coolant sensor is installed after the mixing unit to monitor the temperature leaving the consumer.

Installation methods: overhead (with the obligatory use of thermal-conducting paste, ensuring tight clamping and good thermal contact. Or submersible, in a sleeve specially provided in the line or container, with the obligatory use of heat-conducting silicone oil or heat-conducting paste to ensure reliable thermal contact. The use of oils that destroy plastic is prohibited.

Used in ecoMAX 860 series controllers - pellet burner temperature sensor

Temperature range -25/+125*C.

Execution - in a copper sleeve. The diameter of the sleeve is 5mm, the length of the sleeve is 48mm.
