R410A is very commonly used refrigerant that is known as AZ-20”, “Genetron R410A”, “Puron. It is patented by Honeywell. It is mostly used freon in AC systems and works as a replacement for R22. Here we will make an R410A Pressure-Temperature Chart that will help you find its working for different temperature ranges. use on R-410A refrigerant systems. The low ambient . control pressure sensor is attached to the liquid line of the system, and monitors high side system pressure. Operation of the LAC occurs as outdoor temperatures drop below the 65°F to 50°F range. On/Off LAC operation cycles the condenser fan operation based on outdoor temperature.

The SC might be normal , but the normal head for a r410 system w/ a 68* ambient should be closer to 300psi and the normal suction press should be closer to 110psi w/70* IDB.
