At least my AC indoor unit SRK 35 ZS-S doesn't support the PressureValues, HP and LP (25, 26).
Related to this Source https://www.researchgate.net/publication/225309224_Variable_fuzzy_control_for_heat_pump_operation discharge superheat (Tsh) equals discharge temperature (Td) - condenser temperature (Tc). Tsh = Td - Tc or for an SRK: TDSH = TD - THI-R1.
LP ≙ THI-R1 (Middle of the IndoorCoil/Evaporator in CoolingOperation) and HP ≙ THI-R1 (Middle of the IndoorCoil/Condensor in HeatingOperation).
THI-R1 is the condenser temperature (in HeatingOperation) and can be converted to HP by one of the following Tables: https://hvac-eng.com/refrigerants-p-h-diagram/
The Middle of the OutdoorCoil could be THO-R1. THI-R1 would than analogue HP in CoolingOperation or LP in HeatingOperation.
Closed because of no activity for a long time
Are the PressureValues, HP and LP (25, 26) available for maybe all SRKs or do they get calculated in f.e. the RC-E5 or RC-EX?
