Greetings
I am facing a problem in switching from heating to cooling in Ground source heat pump system and after connecting type 14 to Water-Water Heat pump , where the simulation goes through the heating season normally, but at the beginning of the cooling season, there is a warning at the beginning of operation, that is, every 24 hours until the matter ends with giving an error to increase the number of warnings.
Note: I used type 515 and the simulation did not succeed in switching from heating season to cooling season i.e the whole year the system worked was for heating only.Simulated by TRNSYS 17.
Best regards
