Limitatore di temperatura di sicurezza STB ECOHEAT Gas / ProKondens ET-Pos 287

Safety temperature limiter STB ECOHEAT Gas / ProKondens ET-Pos 287 protects the boiler from overheating by shutting off the burner when the permissible temperature is exceeded. This safety thermostat is an important element of the boiler control system. The part is suitable for ECOHEAT Gas and ProKondens ET models. If the temperature limiter malfunctions, the boiler may operate incorrectly or shut down in emergency. Replacing with an original STB restores safe operation and prevents damage to the heat exchanger.
