Johnson Controls A70AA-16 Temperature Control Freon High-Temperature Protection: Effectively monitors discharge

High-Temperature Protection: Effectively monitors discharge air or heat exchanger temperatures to prevent thermal runaway

Robust Electrical Specs: High-capacity SPDT contacts rated up to 277 VAC support a wide variety of commercial and industrial voltages

This auto-reset limit switch features a ceramic housing to withstand high-temperature environments without the risk of plastic deformation or contact failure

Focus on ensuring proper electrode gap and lead wire insulation during installation to maximize system uptime

facilitating a simplified swap for both the supply and return lines to restore hydronic heating system accuracy and peak performance

Johnson Controls A70AA-16 Temperature Control Freon High-Temperature Protection: Effectively monitors dischargeFor veteran HVACR contractors, the Johnson Controls A70AA 16 Temperature Control is a standard issue solution for heavy duty refrigeration and heating limit applications. Designed as a single pole, single throw (SPST) device, this controller is engineered to open low, breaking the circuit on a temperature drop to prevent coil freeze up or maintain specific thermal boundaries. Operating on 120 240 Vac, it provides high capacity switching for
