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

Q
[0-03]: Low outdoor ambient
temperature. –20°C~5°C (default:
–10°C)
Q

Q
[0-01]: Desired leaving water
temperature when the outdoor
temperature equals or drops below
the low ambient temperature.
Between minimum and maximum
leaving water temperature (default:
40°C).
Note: This value should be higher
than [0-00] as for low outdoor
temperatures warmer water is
required.
Q
[0-00]: Desired leaving water
temperature when the outdoor
temperature equals or rises above
the high ambient temperature.
Between minimum and maximum
leaving water temperature (default:
25°C).
Note: This value should be lower
than [0-01] as for high outdoor
temperatures less warm water is
required.
