Siemens 134 Electric Low Temperature Freeze Stat w/ Automatic Reset, 35/45F, SPDT

The Electric Low Temperature Detection Thermostat is a remote bulb instrument with a Single-Pole Double-Throw (SPDT) switch which closes and opens a circuit in both directions. Applications: The electric low temperature detection thermostats are especially suited for sensing low temperature conditions to avoid freeze-up of hydronic heating coils, cooling coils, liquid heating pipes and similar applications. Typically, the switch opens an electrical circuit to stop the supply fan motor when the temperature at the sensing element falls below the setting of the instrument. Features: Compact and sturdy Adjustable range with fixed differential Unaffected by ambient temperature at case Manual or automatic reset available The set point adjustment screw is accessible at the bottom of the control or at the top with the cover removed Mounting bracket standard
