Johnson Controls P66AAB-34 Control Els PW 17895 Spring Return Reliability: Mechanical fail-safe

Spring Return Reliability: Mechanical fail-safe ensures dampers return to their original position during power interruptions

preventing common system faults such as evaporator freeze-up or inefficient head pressure regulation

Can this replace a standard torque compressor

though it should be positioned in the path of the fan's airflow for proper cooling

This assembly is standard for several York air handler and furnace configurations that utilize a 10x10 or 11x10 wheel depending on the specific tonnage rating

Johnson Controls P66AAB-34 Control Els PW 17895 Spring Return Reliability: Mechanical fail-safeThe Johnson Controls P66AAB 34 is a professional grade electronic fan speed control designed for precise head pressure control in air cooled condensers. Engineered for R 410A systems and other high pressure refrigerants, this direct mount pressure transducer operates within a 320 to 410 psig range to maintain stable condensing temperatures regardless of ambient fluctuations. Unlike standard on off cycles, the P66AAB 34 utilizes a solid state triac
