▪ Which heat emitter types are used in each room and what is their design leaving
water temperature?
Once the space heating requirements are clear, we recommend to follow the setup
guidelines below.
NOTICE
If an external room thermostat is used, the external room thermostat will control the
room frost protection. However, the room frost protection is only possible if the
leaving water temperature control on user interface of the unit is turned ON.
INFORMATION
In case an external room thermostat is used and room frost protection needs to be
guaranteed in all conditions, then you have to set auto emergency [A.6.C] to 1.
NOTICE
An overpressure bypass valve can be integrated in the system. Keep in mind that this
valve might not be shown on the illustrations.
5.2.1 Multiple rooms – Two LWT zones
This unit is designed to deliver water at 2 different temperatures. A typical
installation consists of underfloor heating at a lower temperature and radiators at
a higher water temperature.
In this document:
▪ Main zone = Zone with the lowest design temperature
▪ Additional zone = Zone with the highest design temperature
Typical example:
Room (zone) Heat emitters: Design temperature
Living room (main zone) Underfloor heating: 35°C
Bed rooms (additional zone) Heat pump convectors: 45°C
