thank you for your answers! the idea is that I have both technical floor space and heating and cooling in the concrete slab. so I designed a system in builder design, but I do not think it's correct because it gives me error when simulating: zone is specified as having a radiant surface but no radiant surface in the zone have an internal source set in their construction
