If there is more than one leaving water zone, ALWAYS install a mixing valve station in
the main zone to decrease (in heating)/increase (in cooling) the leaving water
temperature when the additional zone has demand.
Typical example:
Room (zone)
Living room (main zone)
Bed rooms (additional zone)

In cooling mode, you can allow the underfloor heating (main zone) to provide refreshment

temperature zone and the additional leaving water temperature zone in relation to
the required capacity of both water temperature zones.
