Boiler-Sensor ztf 222 (NTC 5k) De Dietrich 300003628

The boiler sensor ztf 222 (ntc 5k) is a temperature sensor used to monitor boiler water temperature. With an NTC 5k characteristic, it provides accurate resistance readings for precise temperature control. This sensor is essential for safe and efficient boiler operation, enabling the controller to modulate burner output. Replacing a faulty sensor helps maintain consistent heating performance and prevents system errors.
