Leaving water temperature: Delta T emitter
Temperature difference for entering and leaving water. The unit is
designed to support under floor loops operation. The recommended
leaving water temperature (set by the user interface) for under floor
loops is 35°C. In such case, the unit will be controlled to realize a
temperature difference of 5°C which means that the entering water
to the unit is around 30°C. Depending on the installed application
(radiators, heat pump convector, under floor loops) or situation, it
can be possible to change the difference between entering and
leaving water temperature. Note that the pump will regulate its flow
to keep the Δt.
