No HVAC Buddy currently doesn't have settings for type of unit or mode setting. Perhaps an enhancement.
My understanding of the charge issues for an ASHP in heating mode:
1) For some manufacturers the subcooling target as well as the target tolerance can be quite different (higher) in heating mode.
2) Your measurements will be taken differently as the indoor coil now acts as the condenser. Instead of wet bulb you have to determine entering dry bulb at the return. Take liquid line temp at the liquid line leaving the indoor coil and take pressure at the service valves at the coil outside.
3) The calculation is still discharge saturation temp less liquid line temp
As far as "clear" that's easy to add and will be in the next update.
Thanks,
Kevin
