INFORMATION

The  leaving  water  is  the  water  that  is  sent  to  the  heat
emitters.  The  desired  leaving  water  temperature  is  set  by
your  installer  in  accordance  with  the  heat  emitter  type.

water  temperature  than  radiators  and  heat  pump
convectors  and/or  fan  coil  units.  You  only  have  to  adjust
leaving water temperature settings in case of problems.

For  more  information  about  the  leaving  water  temperature,  see  the
