NOTICE
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.
NOTICE
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.
