water loops to hot or to cold

I am a student working on my thesis, I must evaluated the robustness of a building with OS (using 2.7.0) The system is a ground heat exchanger with a heat pump (floor heating) and floor cooling with flow to flow heat exchanger. I have the following problem when I run my simulation with a maximum water flow of 0.0004m^3/s. image description

Water is becoming to hot by cooling and by heating to cold and I do not understand how that can be. (all pumps are set intermittent because that was a suggestion found on unmethours)

some one knows how to solve it? you can find the file here. this how the system is modelled image description image description image description

water loops cooling loop to hot or to coldwith heat exchanger fluid to fluid

I am a student working on my thesis, I must evaluated the robustness of a building with OS (using 2.7.0) The system is a ground heat exchanger with a heat pump (floor heating) and floor cooling with flow to flow heat exchanger.

I have the following problem when the water in the floor cooling loop exits his upper limit. I run my simulation with a maximum water flow of 0.0004m^3/s. image description

Water is becoming to hot by cooling and by heating to cold and I do not understand how 0.00038m^3/s. image description

I also get the error that can be. (all pumps are set intermittent there is condensation in my floors. (I think this is because that was a suggestion found on unmethours)of the error in the floor cooling loop) image description

If I run my weather file from April to October. I get the errors mentioned above but, if I run for a whole year then I get the following error. That the temperatures of glycol gets to low. image description

some one knows how to solve it? you can find the file here. and also the used weatherfile. this how the system is modelled image description image description image description
