De Dietrich S101005 HL temperature sensor

Original De Dietrich Temperature Sensor S101005 HL (High-Limit Safety Thermostat) is a factory-grade, high-reliability component designed for De Dietrich boiler series MCA (10, 15, 25, 35, 45, 65, 90, 115 kW), AGC 10–25, and EGC 17/29. This temperature sensor monitors overheating — when the temperature exceeds the safety limit, it opens the HLS contact and sends a shutdown signal to the boiler control unit. Key advantages: OEM quality from De Dietrich — ensures stable operation throughout the boiler's lifetime. Easy replacement: 2-wire connector, mounted directly to the boiler casing, no soldering required. Designed solely for high-limit temperature control (HL), not a replacement for an NTC sensor. Compact, sealed, and heat-resistant housing for long-term durability. Compatibility and application: Suitable for service and maintenance of De Dietrich boilers up to 115 kW. Most commonly installed as an emergency HL thermostat for monitoring flow temperature. Ideal replacement when overheat protection is triggered (OverTemp, E2, e05 error codes). The HL temperature sensor S101005 is used in the following De Dietrich boilers: C 230 ECO, C 310 / 610 ECO, M 40-S, C 210 ECO, DOMOGAS DGXECO/DGXE AB 05.98, MCR...MI, DTG 1200V ECONOX, DTG 230 ECONOX, GT 430, DTG 120 NEZ Diematic, DOMOGAS DGXE 14-47 until 04.95, MC 65/MC 90, 200/1S, WHE 2.24 FF, DOMOGAS DGXE 60 - 110.
