Johnson Controls A70HA-2 Temperature Control R-410A Incorrect wiring on the high-voltage

Incorrect wiring on the high-voltage side will immediately blow the internal windings

Burner degradation is often caused by high humidity in the mechanical room

ensuring your system enters a safe state during high-pressure or cold-start faults to prevent catastrophic equipment failure

the DFBK01 maintains system heat pump efficiency by preventing excessive frost buildup on the evaporator coil during low-ambient heating modes

Common in Goodman gas furnaces and Amana heating systems

Johnson Controls A70HA-2 Temperature Control R-410A Incorrect wiring on the high-voltageThe Johnson Controls A70HA 2 is a heavy duty single pole temperature control engineered for high limit cutout applications in both refrigeration and heating systems. Operating within a 35F to 80F temperature range, this controller features a critical open low action with a lockout manual reset mechanism, ensuring system safety by preventing automatic restarts after a limit trip. The unit is equipped with a 6 foot capillary for flexible sensing bulb
