[TRNSYS-users] heat pump 927 error

[Swarnim Singh]

Dear makers,
the heat pump type 927 is not working according to its specifications.
Instead of upgrading the source heat it is returning it at  the same temp
it is entering where the load in and load out are equal to the input load
cold temp. Can you help me out why this is happening? I have already
checked the connections. The cold water is load in of HP and Load out goes
to the tank while Source in of heat is from Solar collector and source
out(which is supposed to be cold) is going back to collector i will attach
an image of the plotter output,..please help me out...

with warm regards,
TRNSYS 18 user from India
