This L170-30F limit control is engineered to open the electrical circuit at 170°F and automatically reset once the temperature drops by 30°F to 140°F

Enhanced Efficiency: The 1/3HP 115V motor design balances power consumption with high-torque output for consistent air distribution

and primary relays

maintaining the thermal efficiency required for consistent heating and cooling cycles

MAMAC Systems TE-701-B-7-A Temperature Sensor 318820-201 This L170-30F limit control isThe MAMAC Systems TE 701 B 7 A is a precision duct temperature sensor engineered for building automation systems and mechanical equipment monitoring. This model features a high stability 10,000 Ohm NTC Thermistor (Type III) sensing element, providing highly accurate and repeatable resistance output for direct digital control (DDC) applications. The 4 inch 304 stainless steel probe is hermetically sealed to prevent moisture migration and contamination,
