Good morning, I am building a detached house with an installation of radiant floor heating and cooling. I have placed thermostats in the therma zone.

I have made these systems:

-A geothermal pump loop with horizontal ground heat exchanger (supply) and with two water-water heat pumps, one for hot water and one for cold water (demand).

-Hot water circuit connected to the radiant floor heating system.

-Cold water circuit connected to the radiant floor cooling system

I have placed thermostats in the thermal zones and all these circuits have setpoins, pre-circulation pumps and pipes.

When I start the simulation everything goes well but when I get to the results I do not see any heating or cooling consumption (this has never happened to me before and and I haven't found similar errors in the forum)

I attach some images and the file.

Can someone please help me?

Regards, Pablo
