Hi,
I am trying to Simulate a heat pump assisted solar system but I am getting
error 427. I dont know how to figure it out. Could you please help me out.
Attached with this email are my project files. Also previously I was not
getting any flow through out my system (Any idea), I dont know what will
happen after figuring this error out? Last thing is there any other way I
can Simulate heat pump without having manufacture's data?
Looking forward to hearing from you.
Kindest Regards
