CAUTION
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)
Heat emitters: Design temperature
Living room (main zone)
Underfloor heating:
▪
In heating: 35°C
▪
In cooling: 20°C (only refreshment, no
real cooling allowed)
Bed rooms (additional zone)
Heat pump convectors:
▪
In heating: 45°C
▪
In cooling: 12°C

INFORMATION
A pressure regulating valve should be implemented before the mixing valve station.
This is to guarantee the correct water flow balance between the main leaving water
temperature zone and the additional leaving water temperature zone in relation to
the required capacity of both water temperature zones.
