This calculates to Super Heat of 12 more or less.

Cooling. In the cooling mode, running in outdoor temperatures below 55 degree without a "low ambient control' will cause symptoms very similar to low refrigerant. The cold outside air will cause the head pressure to drop which, in-turn, causes the suction pressure to drop. Try blocking part of the outdoor fan discharge to increase head pressure.

What are normal operating pressures for 410A mini split? The low side pressure of a typical R410A mini split is between 110-140 psi depending on the operating conditions.
