Your cart is empty.The electric low temperature detection thermostat is a vapor filled remote bulb instrument with a single-pole double-throw (SPDT) switch which closes and opens a circuit in both directions. This is 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. Any 1-foot length of the element subjected to temperatures below the temperature setting of the thermostat wall actuate the thermostat switch mechanism regardless of the temperature being sensed by the remainder of the element. The sensing element is unaffected by the ambient temperature at the thermostat if it is warmer than the set point temperature.
