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, 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.

Description
[A.3.1.3.1]
[9-09]
Heating: required temperature
difference between entering and
leaving water. Range: 3°C~10°C (in
steps of 1°C; default value: 5°C).
[A.3.1.3.2]
[9-0A]
Cooling: required temperature
difference between entering and
leaving water. Range: 3°C~10°C (in
steps of 1°C; default value: 5°C).
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
modulation, the desired leaving water temperature will be calculated
automatically by the unit (based on the preset temperatures, if
weather-dependent is selected, modulation will be done based on
the desired weather-dependent temperatures); when turning off the
modulation, you can set the desired leaving water temperature on
the user interface. Moreover, with the modulation turned on, the
desired leaving water temperature is lowered or raised in function of
the desired room temperature and the difference between the actual
and the desired room temperature. This results in:
▪ stable room temperatures exactly matching the desired
temperature (higher comfort level)
▪ less On/OFF cycles (lower noise level, higher comfort and higher
efficiency)
