Leaving water temperature: Delta T source
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, under floor loops) or situation, it can be possible to
T a
change the difference between entering and leaving water
temperature. Note that the pump will regulate its flow to keep the Δt.

Leaving water temperature: Modulation
Only applicable in case of room thermostat control. When using the
room thermostat functionality, the customer needs to set the desired
room temperature. The unit will supply hot water to the heat emitters
and the room will be heated. Additionally, also the desired leaving
water temperature must be configured: when turning on the

In case a minimum temperature
difference is required for the good
operation of the heat emitters in heating
mode.
Range: 3°C~10°C (in steps of 1°C;
default: 5°C)
Cooling: required temperature
difference between entering and
leaving water.
In case a minimum temperature
difference is required for the good
operation of the heat emitters in cooling
mode.
