Siemens Building Technology 134-1510 Thermostat 321894-706 directly contributing to the long-termThe Siemens Building Technology 134 1510 is a heavy duty low temperature detection thermostat designed to protect hydronic heating coils, cooling coils, and liquid pipes from specialized freeze up conditions. Engineered for precision, this freeze stat features a 20 foot vapor filled capillary element that triggers the switch if any one foot section of the bulb senses a temperature below the setpoint. This makes it a critical component for monitoring
