Under floor heating systems
The external circulation pump is dimensioned for the
under floor heating system's demand.
To ensure a heating supply during hot water production,
the heating system can be supplemented with a NIBE
UKV vessel, e.g. when there is a water coil in the FTX
ventilation.
Two or more climate systems
When more than one climate system, with a lower tem-
perature, is to be heated up, the following connection
can be used. The shunt valve lowers the temperature to,
for example, the under floor heating system.
The ECS 40/ECS 41 accessory is required for this connec-
tion.

Charging of the pool is controlled by the pool sensor. In
the case of low pool temperatures, the shuttle valve re-
