# Code Description

[4.4] [7‑02] ▪ 1: Dual zone

Two leaving water temperature zones. The

main leaving water temperature zone consists

of the higher load heat emitters and a mixing

station to achieve the desired leaving water

temperature. In heating:

a Additional LWT zone: Highest temperature

b Main LWT zone: Lowest temperature

c Mixing station

CAUTION

NOT configuring the system in the following way can cause damage to the heat

emitters. If there are 2 zones, it is important that in heating:

▪ the zone with the lowest water temperature is configured as the main zone, and

▪ the zone with the highest water temperature is configured as the additional zone.

CAUTION

If there are 2 zones and the emitter types are wrongly configured, water of high

temperature can be sent towards a low temperature emitter (underfloor heating). To

avoid this:

▪ Install an aquastat/thermostatic valve to avoid too high temperatures towards a

low temperature emitter.

▪ Make sure you set the emitter types for the main zone [2.7] and for the

additional zone [3.7] correctly in accordance with the connected emitter.
