Re: [TRNSYS-users] Problem with QHEAT

[hotline <hotline@Transsolar.com>]

Dear Wirich,

unfortunately I couldn't reproduce your problem with the attached files. NTYPE 30 - Qheat as well as Balance-4 varies to reach the set temperatures of 16°C and 22°C.
As weather file I used FR-Nice_76900.tm2. I have also tested it with limited/unlimited and with/without TRNFlow.

Best,
Christoph

Dear TRNSYS users,

I don't find any solution to get the real Qheat. Though in the SUMMARY.BAL file, the total Qheat changes when I change the heating system. So it definitely works.

I attach to this mail some files that could help you find the problem.

Thank you in advance

Best regards
