This machine is not configured for automatically setting charge by superheat / subcooling based on real time feedback from wireless hygrometer?

[@NAVAC]

Hello. You cannot automatically charge by superheat/subcooling. You can only monitor the values. Then you will have to manually charge the unit based on your calculations. It would be very difficult to do automatically because very equipment is different while the machine doesn't know.

@@NAVAC I developed an app that measures indoor wet bulb, indoor and outdoor ambient and based on that calculates target superheat and target supply air temperatures.
I've been considering an interface of that with a solenoid operated manifold, suction and discharge transducers (both temp and pressure), to fully automate the entire process.
It would be even easier in the case of txv, the technician would only need to provide the specified target subcooling.
