6.2.3 Multiple rooms – Two LWT zones
If the heat emitters selected for each room are designed for different leaving water
temperatures, you can use different leaving water temperature zones (maximum
2).
In this document:
▪ Main zone = Zone with the lowest design temperature in heating, and the highest
design temperature in cooling
▪ Additional zone = Zone with the highest design temperature in heating, and the
lowest design temperature in cooling
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
